Means provided with an actuating protrusion for standing and tilting the air guide against the biasing force of the means.

In addition, the above-mentioned fully opened region refers to a region near the fully opened position including the fully opened position.

Further, as one of the constituent members of the air guide tilting mechanism, a standing spring for constantly biasing the air guide in the standing direction is provided, and the fall biasing means is rotatably supported by the vehicle body. An operating lever capable of transmitting drive to the air guide in the tilting and tilting direction and a biasing force for turning the operating lever in the tilting and tilting direction are provided, and the biasing force thereof is larger than the biasing force of the upright spring. A set fallen spring is provided, and the actuating projection is a position that engages with the actuating lever and rotates the actuating lever against the biasing force of the fallen spring by sliding in the opening direction in the fully open region of the lid. It may be arranged at.

Further, as the fall biasing means, a fall spring provided at the tilt center of the air guide for biasing the air guide directly in the fall direction is provided, and the air guide is rotatable in conjunction with the air guide. The actuation link is connected to the actuation link, and the actuation projection slides in the opening direction in the fully open region of the lid to engage with the actuation link to tilt the air guide in a fallen state against the urging force of the fallen spring. Therefore, the operating link may be arranged at a position to rotate.

(Operation) In the air guide device configured as described above, when the lid of the outer slide device is slid in the opening direction to reach the fully opened region, the operation protrusion provided on the back surface of the lid is
The air guide is erected and tilted against the urging force of the fallen urging means, and the air guide closes the gap formed between the front end portion of the lid in the fully opened position and the vehicle body.

This operation will be described in detail. In the device according to claim 2 of the utility model registration claim, when the lid is slid to the fully open region, the actuating protrusion engages with the actuating lever to cause the actuating lever to fall over. Rotate against the biasing force of. As a result, the biasing force transmitted from the actuating lever to the air guide in the tilting and tilting direction ceases to act, and the air guide rises and tilts due to the biasing force of the rising spring to close up the gap. On the other hand, in the device described in claim 3 of the utility model registration claim, the operating protrusion engages with the operating link connected to the air guide to rotate the operating link, and the operating link interlocks with the operating link. The guide tilts upright against the biasing force of the fall spring.

On the other hand, when the lid is slid in the closing direction from the fully open position, as the actuating projection moves with the lid, there is no force against the biasing force of the fall biasing means, and the fall bias acts on the air guide. The biasing force of the means is strengthened, and the biasing force causes the air guide to fall and tilt and separate from the lid.

This operation will be described more concretely. In the device described in the second aspect of the utility model registration claim, when the lid is slid from the fully open position, the actuating lever moves with the fall spring as the actuating projection moves. Starting to rotate due to the force, the urging force is transmitted to the air guide.

When the actuating protrusion and the actuating lever are disengaged, the biasing force of the fall spring transmitted to the air guide exceeds the biasing force of the upright spring that biases the air guide in the upright direction, and the air guide falls down. It rotates in the direction and is kept in the prone state. Further, in the device described in claim 3 of the utility model registration claim, when the lid is slid from the fully open position, the operating projection and the operating link are disengaged, and the air guide falls down by the urging force of the fallen spring. Tilt until the state is reached.

Therefore, in the air guide device of the present invention, the air guide does not contact the lid when sliding outside the fully open region of the lid, and the air guide and the lid do not rub against each other.

Located at a distance from 14 and the rail roof rear
It is supported by a bracket 32 so as to be tiltable around a tilting shaft 31 until a fall state d in which the tip is close to 112.

A flange portion 33 is formed at the base end of the air guide 30 at an angle to the air guide 30.

The air guide tilting mechanism 40 is provided between the air guide 30 and the lid 14 and controls tilting of the air guide 30 from the standing state c to the fallen state d. The air guide tilting mechanism 40 includes a standing spring 41, The main components are a fall spring (falling biasing means) 42, a slide block (falling biasing means) 43, an operating lever (falling biasing means) 44, and an operating projection 45.

The upright spring 41 biases the air guide 30 in the upright tilt direction e, and is provided on the tilt shaft 31.

The slide block 43 is a flange portion of the air guide 30.
It is slidable in the front-rear direction, which is a direction orthogonal to the tilting shaft 31, with respect to 33, and is supported by a support bracket 431 so that its tip end abuts the flange portion 33 at the upper position of the tilting shaft 31. That is, the slide block 43 pushes the flange portion 33 by sliding forward and pushes the air guide 30.
By tilting and tilting and removing the pressing force on the flange portion 33 by rearward sliding, the upright tilt of the air guide 30 by the urging force of the upright spring 41 is allowed.

The actuating lever 44 is supported by a support bracket 441 on the rail roof rear 112 at the rear position of the slide block 43 so as to be tiltable about an axis parallel to the tilt axis 31, and is provided with a long hole 442 for the slide block 43. An output lever 443 connected to the output lever 443 and an input lever 444 forming a right angle with respect to the output lever 443;
The operating lever 44 is provided with a fall spring 42 that biases the lever forward.

The fall spring 42 is for biasing the operating lever 44 forward and biasing the slide block 43 forward so as to maintain the flat state of the air guide 30. For 30, a spring having an elastic force capable of obtaining a fall tilting biasing force stronger than the standing rotation biasing force of the standing spring 41 is used.

As shown in FIG. 1, the actuating protrusion 45 is hung from the frame 141 on the rear surface of the front end portion of the lid 14, and
Of the operating lever 44 in contact with the input lever 444 of the operating lever 44 in the fully open region g which is the slide range immediately before the fully opening including the fully open position b of the operating lever 44.
Is arranged at a position where it can be tilted. still,
The fully open region g is equal to a range h in which the actuating protrusion 45 contacts the input lever 444.

Next, the operation of the embodiment will be described.

The operating lever 44 is normally tilted forward (when the lid 14 is not fully opened) by the biasing force of the fall spring 42, and the forward tilting causes the slide block 43 connected to the output lever 443.
Is slid forward so as to bring the air guide 30 into the lying state d against the biasing force of the upright spring 41, and is held at that position. The urging force of the fall spring 42 keeps the air guide 30 in the fall state d.

In this lying state d, the air guide 30 is at a position where its tip is close to the rail roof rear 112 as shown in FIG. 1, that is, when the lid 14 is fully closed and slid.
It is arranged at a position spaced apart from.

Therefore, when the lid 14 is closed or when sliding in a range other than the fully open region g, the air guide 30 does not come into contact with the lid 14, and the air guide 30 and the lid 14 rub against each other and wear or make a rubbing noise. I can't do it.

Next, slide the lid 14 in the opening direction,
When reaches the fully open region g, the following operation is performed in the air guide tilting mechanism 40 in conjunction with this sliding in the opening direction.

First, the operating protrusion 45 provided on the lid 14 is attached to the operating lever 44.
The operating lever 44 is tilted rearward by hitting the input piece 444 and moving backward. When the operating lever 44 tilts rearward, the slide block 43 is slid rearward, which removes the biasing force of the fall spring 42 that the slide block 43 has applied to the air guide 30, and the air guide 30 is attached to the upright spring 41. It is erected and tilted by the power, and its tip comes into contact with the front end of the lid 14 and the gap S is closed to be in an erected state.

Next, when the lid 14 is slid in the closing direction from the fully open position b by the slide mechanism 20, the air guide tilting mechanism 40 operates as follows in conjunction with this sliding.

When the operating protrusion 45 moves forward in response to the sliding of the lid 14, the operating lever 44 is tilted forward by the biasing force of the fall spring 42, the slide block 43 is slid forward with it, and the air guide 30 moves the upright spring 41. The flange portion 33 is pressed by the urging force of the lodging spring 42 which is higher, and tilted and tilted until the laid state d is reached.

Therefore, when the lid 14 slides in the closing direction after the fully open region g, the air guide 30 is arranged with a space from the lid 14 and does not rub against the lid 14. Further, the back surface of the lid 14 does not need to be smooth except for the front end portion provided with the actuating protrusion 45 that comes into contact with the air guide 30 in the fully open region g.

As described above, the air guide device of the first embodiment has the effect of being applied to the outer slide roof device unlike the prior art, and the slide except the fully open region of the lid 14 can be obtained. At this time, the effect that the air guide 30 does not rub against the lid 14 and the air guide 30 does not wear or generate a rubbing sound due to the rubbing.

Next, the air guide device of the second embodiment corresponding to the embodiment described in the third item of the claim for utility model shown in FIG. 4 will be explained.

The apparatus according to the second embodiment includes an air guide 201 and an air guide tilting mechanism 202. The air guide tilting mechanism 202 includes a fall spring 203, an operating link 204, and an operating lever (an operating protrusion).
205 is the main component.

The air guide 201 is biased in a tilting and tilting direction by a falling spring 203, and is supported by an operation link 204 on the lower side. Support bracket 2
It is regulated by a stopper 207 provided on 06.

The actuating lever 205 is hung on the frame 141 of the lid 14 and is interlocked with the slide in the fully open region g to actuate the link.
It is provided at a position where the air guide 201 can be raised and tilted by pushing up 204.

Therefore, also in this embodiment, the lid is the same as in the first embodiment.
The air guide 201 is erected and tilted in association with the opening direction slide in the fully open region g, and the air guide 201 is tilted and tilted in conjunction with the closing direction slide in the fully open region. In this fallen state, the urging force of the fallen spring 203 presses the operation link 204 against the stopper 207 to regulate the position, whereby the fallen state of the air guide 201 is maintained.

Therefore, the air guide 201 does not rub against the lid 14 when sliding with respect to the fully closed position of the lid 14, and an effect that no wear or rubbing noise is generated is obtained.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment. For example, in the case where the present invention is applied to a roof having a shape generally called a T-bar roof. , But is not limited to this. Therefore, an air guide having a width corresponding to the entire width of the lid may be provided instead of providing two air guides on the left and right with the center bar interposed therebetween as in the present embodiment.

(Effects of the Invention) As described above, the air guide device of the present invention is provided with the air guide tilting mechanism that tilts and tilts the air guide until it is arranged with a space from the lid outside the fully open region. Since the air guide does not come into contact with the lid when sliding outside the fully open region, it is possible to prevent the air guide and the lid from wearing and rubbing noise due to vibration during traveling. The effect is obtained.
