The engagement pin 37a is disposed so as to come into elastic contact only with the groove surface of the cam groove 24, and is deviated from the movement locus of the engagement pin 37a.

Next, the action will be explained.

In FIG. 5, the opening/closing body 20 is fully opened, and the sliding shoe 37 of the movable member 36 is positioned at the end of the fully open guide portion 24a of the cam groove 24 and stopped. The holding hook member 35 engages with the side edge 14 of the roof opening 11 to restrict movement of the rear support base 33, and the moving member 36 in the fully open guide portion 24a of the cam groove 24
The restraining portion 25 rides on and presses against the engaging element 37b of the sliding shoe 37, suppressing rattling between the sliding shoe 37 and the cam groove 24, and the connecting spring 34
The opening/closing body 20 is also urged downward and held so that it does not wobble.

When the electric motor 12a of the drive unit 12 is operated and the geared cable 13 is moved vertically by the drive gear 12b, the moving member 36 fixed to the geared cable 13 is driven to move rightward in FIG. The sliding shoe 37 moves from the full opening guide part 24a of the cam groove 24 to the opening/closing guide part 24b, and pulls down the tilting arm 22 downward according to the inclination of the opening/closing guide part 24b. The support base 31 tilts around the pivot 32 to close the door, and the connecting spring 34
pushes the opening/closing body 20 slightly forward.

When the opening/closing body 20 is slightly closed and stopped, the sliding shoe 37 of the movable member 36 has moved to the beginning of the opening/closing guide part 24b, but there the restraining part 25 still rides on the engaging element 37b and presses against it. This reduces rattling. When the opening/closing body 20 is further closed, the sliding shoe 37 moves to a portion where the restraining portion 25 is not provided, so the sliding shoe 37 is loosely engaged with the cam groove 24 and slides smoothly.

Note that when the sliding shoe 37 moves with the restraining portion 25 in pressure contact with the engaging element 37b, the engaging pin 37a comes into contact with the lower groove surface of the cam groove 24, and the engaging element 37b restrains the upper side. Since they rotate while abutting on the portions 25, the operation is light and the opening/closing body 20 can be opened and closed smoothly.

As shown in FIG. 4, when the sliding shoe 37 of the movable member 36 reaches the fully closed guide portion 24c at the rear end of the cam groove 24, the sealing member 23 comes into close contact with the sealing surface 15 of the roof opening 11 and the opening/closing body 20 is fully opened. Even when the opening/closing body 20 is held in the fully closed state, the restraining portion 25 provided on the fully closing guide portion 24c
Since it rests on 7b and is pressed against it, rattling is suppressed.

When the movable member 36 is moved to the left in FIG. 4 from the fully closed state of the opening/closing body 20 and returned, the opening/closing body 20 and the cover plate 21 can be fully opened in the reverse operation.

When the moving member 36 is moved to the right in FIG. 4 from the fully closed state of the opening/closing body 20, the moving member 3
The sliding shoe 37 of No. 6 moves within the retractable guide portion 24d, the rear end of the cover plate 21 and the seal member 23 retract inward from the roof opening 11, and the sliding shoe 37 moves within the retractable guide portion 24d. Moving member 36 until
When the release end 36a moves, the holding hook member 3
5 to release the restriction state with the side edge 14, and the rear support base 33 is movable rearward.
The state shown in the figure will be reached. Even in this state, the cam groove 2
The restraining part 25 on the retraction guide part 24d of No. 4 rides on and presses against the engaging element 37b of the sliding shoe 37 of the moving member 36, thereby suppressing rattling between the sliding shoe 37 and the cam groove 24.

When the movable member 36 is further moved rearward, the rear support base 33 is pushed by the movable member 36 and slides rearward, and the opening/closing body 20 is stored under the roof 10 and the front part of the roof opening 11 is moved. open. When the movable member 36 is returned and the opening/closing body 20 is closed, the holding hook member 35 engages with the side edge 14 of the roof opening 11 to restrict the forward movement of the opening/closing body 20, contrary to the above case. After that, the opening/closing body 20 is fully opened.

In the above embodiment, the restraining portions 25 are separately provided at appropriate locations along the cam grooves 24 of the raising/lowering arm 22, but they may be provided all along the cam grooves 24.

Furthermore, in the above embodiments, the opening/closing body tilts to open/close and slides to open/close, but it goes without saying that the opening/closing body may open/close only by tilting.

"Effects of the Invention" According to the vehicle sunroof device according to the present invention,
Since we have provided restraining parts that come into pressure contact with the engaging elements of the sliding shoe that engages with the cam grooves at key points along the cam grooves, when the opening/closing body is stationary or in the vicinity,
The restraint part makes elastic contact with the engaging element of the sliding shoe and presses the engaging pin against either the upper or lower groove surface of the cam groove, so there is no rattling, providing comfort for the occupants and advantageous in terms of strength as no impact load is generated. It becomes a structure. Further, when the sliding shoe slides in the cam groove, the engaging pin contacts only the lower side and the engager rotates only the upper side, so that the opening and closing body can be opened and closed smoothly.
