More specifically, each side deflector 5 is made of a hard resin material or the like, and is bent outward at a substantially right angle from the outer wall 5a having a curved surface bulging outward and the upper portion of the outer wall 5a. The formed inner side wall 5b is formed into a three-dimensional cover shape having an opened lower surface. And
The pair of side deflectors 5 are arranged such that the inner side walls 5b face each other. Further, in the front portion of each side deflector 5, a part of the inner wall is cut out, and a partition wall 5c is continuously provided from the cutout portion to the inner surface of the outer wall 5a. 30 is made, and the pressing member 31, the control member 32, and the like are arranged in the space 30. Among these, the pressing member 31 is rotatably supported at its intermediate portion by a support shaft 33 fixed to the side deflector 5. In addition, one end 31a of the pressing member 31
When the pressing member 31 is rotated in the clockwise direction in FIG. 3, it extends so as to come into contact with the elastic sealing material 34, and a rubber sealing material is provided at the tip of the one end 31a. 35 is attached. On the other hand, a long hole 36 is formed on the other end 31b side of the pressing member 31, and a pin 37 is engaged with the long hole 36 to link the control member 32 to the link. The control member 32 is supported by the side deflector 5 so as to be horizontally movable, and the tip end portion protruding from the side deflector 5 onto the outer rail portion 2c is gradually protruded from the rear side to the front side. An inclined surface 32a (see FIG. 4) is formed in a rising state. Further, pins 38 and 40 are planted in the side deflector 5 and the pressing member 31, respectively, and a coil spring 39 is stretched between the pins 38 and 40. The pressing force of the coil spring 39 constantly urges the pressing member 31 in the counterclockwise direction in FIGS. 3, 5, and 6. Further, since the pressing member 31 and the control member 32 are linked to each other, the pressing member 31 is rotationally displaced in the counterclockwise direction and one end 31a is drawn into the space portion 30. As shown in FIG. 6, the control member 32 is largely projected on the outer rail 2c. On the contrary, when the control member 32 is pushed back against the urging force of the coil spring 39, the pressing member 31 is rotated in the clockwise direction, and the one end 31a is brought into contact with the elastic sealing material 34 as shown in FIG. The state of being contacted is obtained.

On the other hand, the canvas 7 is formed of a flexible cloth or a sheet material such as vinyl chloride, and at the time of forming the canvas 7, the shape-retaining wires 45 are provided inside the left and right sides.
Then, when the front end 7a side of the canvas 7 is moved to the rear end 7b side via a driving means (not shown), the predetermined numeral 8 (7th shape) is used for a shape-retaining aggregate (not shown). (See figure)
Bending is sequentially obtained at the portion indicated by, and the bellows are folded and retracted. Furthermore, on the front end 7a of the canvas 7,
A plate-shaped cover plate 9 connected to the front end 7a is provided. The cover plate 9 is made of a hard plate material, etc., and the rollers 20 are rotatably attached to both left and right ends via a support leg piece 21 and a support shaft 22.

Next, the guide rail 6 is provided on the roof 2 as shown in FIG. 3 which is an enlarged sectional view of an essential part taken along the line AA of FIG.
Are supported by a part of the inner wall of the opening 3 and are arranged along the inner surfaces of the left and right sides of the opening 3. Each of the guide rails 6 has a guide groove portion 6a that is open toward the inside, and the roller 20 is rotatably arranged in the guide groove portion 6a.
Then, by the rolling of the roller 20, the front end 7a of the canvas 7 can slide on the opening 3.
Further, when the canvas 7 is pulled forward and the opening 3 is closed, the front end portion of the cover plate 9 is attached to the inclined surface 32a of the control member 32 protruding to the outer rail 2 by the biasing force of the coil spring 39. Abut. Then, the control member 32 is moved to the inside of the side deflector 5 by a coil spring.
It is ready to be pushed against the urging force of 39. In FIG. 3, a member indicated by reference numeral 25 is a molded ceiling plate, a member indicated by reference numeral 26 is a garnish, and a member indicated by reference numeral 27 is a weather strip that seals between the door glass 28 and the roof 2.

In the automobile 1 configured as described above, when the canvas 7 is expanded as shown in FIG.

Further, in this state, the control member 32 is forcibly pushed into the side deflector 5 by the cover plate 9 that is in contact with the inclined surface 32a. At the same time, the pressing member 31 also controls the coil spring 39.
As shown in FIGS. 3 and 5, the displacement force from 32 causes the canvas 7 to be rotationally displaced to the “first position” in which the elastic seal member 34 is pressed against the elastic seal member 34. Then, the lower surface of the canvas 7 is pressed against the roof 2 by the pressing force of the pressing member 31 via the elastic sealing material 34,
The canvas 7 is firmly held on the roof 2.

Next, when opening the opening 3, the front end 7a of the canvas 7 is pushed rearward together with the cover plate 9 to move against the pressing force of the pressing member 31. Then, the canvas 7 is sequentially folded into a bellows shape and retracted to the rear end portion 7b side. Further, when the cover plate 9 comes out of the area corresponding to the control member 11, the control member 32 is moved from the inside of the side deflector 5 to the outer rail portion 2c by the urging force of the coil spring 39.
It sticks up. At the same time, the pressing member 31 is applied to the canvas 7.
The "second position" that is rotated in the direction in which the pressure contact with is released and retracted into the side deflector 5 as shown in FIG.
Is displaced to.

Next, when closing the opening 3 with the canvas 7 again, the front end 7a is moved forward together with the cover plate 9. Then, the canvas 7 folded on the rear side is sequentially delivered to the front side. Then, immediately before the cover plate 9 is pulled to completely close the opening 3, the cover plate 9 collides with the inclined surface 32 a of the control member 32. As a result, the control member 32 is pushed into the side deflector 5, and conversely, the pressing member 31 is rotationally displaced from the "second position" to the "first position", and is pressed against the canvas 7 at the final position. . Then, the state shown in FIGS. 1 and 5 is again established, and the canvas 7 is held with the opening 3 closed.

Therefore, in the canvas top structure of this automobile, the opening is closed by the canvas 7, and at the same time, the pressing member 31 forcibly presses and holds the canvas 7 toward the roof 2, so that the close contact between the canvas 7 and the roof 2 occurs. The sex is stronger. As a result, the cooling and heating effects, the watertightness and the sound insulation are improved, and the fluttering sound of the canvas during traveling is eliminated, and the riding comfort is improved.

In the above embodiment, the control member 32 has been described as a structure in which the opening / closing of the canvas 7 is detected and moved to automatically control the pressing member 31, but the operation of the control member 32 is performed by another driving means. The structure may be such that it can be operated freely. Of course, the present invention can be variously modified within the scope of the invention.

[Effects of the Invention] As described above, according to the canvas top structure for an automobile of the present invention, the pressing member is moved from the second position to the first position by the control of the control member after the canvas is closed. Can be made. By this movement, the pressing member is pressed against the canvas, and the canvas can be pressed against the roof side. As a result, the canvas and the roof are strongly adhered to each other, and the sealing property between the canvas and the roof is enhanced. At the same time, the fluttering sound of the canvas when driving is eliminated. As a result, the cooling / heating effect, watertightness, and sound insulation are improved, and the riding comfort is improved.
