Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push / pull
The present invention relates to a sunroof device having an opening and closing panel connected to a slider driven by a cable. 2. Description of the Related Art There is known a sunroof device that opens and closes an opening provided in a vehicle body roof with a slide panel. In this sunroof device, generally, a flexible wire (hereinafter referred to as a push / wire) having a spiral strip around which a piano wire is wound is formed around the spiral strip.
The pull / cable is inserted into a substantially tubular guide hole, and the push / pull cable is linearly moved by rotating a pinion engaged with the spiral strip with a motor, thereby opening and closing the slide panel. The exercise is performed (Japanese Patent Laid-Open No. 2000-283256).
Reference). [0003] The push / pull as described above
In the case of a drive device that uses a pull cable to open and close the slide panel, there is no problem in pulling the cable because the cable is stretched. Contacting the inner peripheral surface of the In particular, when the slide panel stops at the tilt-up limit, which is the push-direction movement limit in the tilt-type sunroof device, the amount of flexure of the cable becomes excessive due to overrun of the motor, and a spiral streak is formed on the inner peripheral surface of the guide hole. Sometimes a popping sound was heard. [0004] The generation of such a popping sound is not preferable because it impairs the texture of the automobile. The present invention has been devised in order to solve such a problem of the prior art, and a main object of the present invention is to provide a push / pull cable when a slide panel stops at a tilt-up limit or the like. It is an object of the present invention to provide a sunroof panel driving device improved so as to be able to reduce the repelling sound generated by the sunroof panel. According to the present invention, there is provided an opening / closing panel connected to a slider (rear slider 15) driven by a push / pull cable (24). The sunroof device having the (slide panel 3) is placed on the push operation limit side of the cable guide hole (32) through which the push / pull cable is inserted,
Buffer (35) against which the tip of the push / pull cable abuts before the slider reaches the mechanical advance limit
Is provided. With this arrangement, the tip of the push / pull cable comes into contact with the buffer member before the slide panel stops, and the amount of bending of the push / pull cable increases slowly, so that a popping sound is generated. Is suppressed. The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a main part of a vehicle showing an outline of a sunroof device to which the present invention is applied. An opening 2 having a substantially rectangular shape is formed in a fixed roof 1 of the vehicle.
The opening 2 can be opened and closed by a slide panel 3 formed in a shape corresponding to the inner peripheral contour of the opening 2. As shown in FIGS. 2 to 4, the slide panel 3 is composed of a glass panel 4 and a metal plate-made glass holder 5 fixed below the outer periphery of the glass panel 4 with an adhesive. . Below the left and right sides of the glass holder 5, a pair of left and right side plates 11 is provided via stays 6 (see FIG. 5).
Are combined. A front slider 12 is connected to each front end of the both side plates 11 with a pin shaft 13.
In each intermediate portion of both side plates 11, a cam groove 14 formed to perform a tilt operation and a slide operation is provided.
The rear slider 15 is connected with a pin shaft 16. The front and rear sliders 12 and 15 are fixed roof 1
And slides back and forth with respect to a guide groove (to be described later) formed in a guide rail 17 fixedly provided in the inside. The front slider 12 has a slide panel 3
A lock lever 18 for restricting the forward and backward movement of the slide panel 3 at the forward movement limit of the slide panel 3 is connected.
The lock lever 18 is supported by a front slider 12 with a shaft 19 so as to be tiltable in a seesaw manner at an intermediate portion in the front-rear direction. The lock lever 18 has a downward engaging projection 20 projecting from its front end, and an upward pressing projection 21 projecting from its rear end. At the front end of the guide rail 17, there is provided a stopper 22 for defining a forward limit of the front slider 12, and this stopper 22 is engaged with an engagement projection 20 of the lock lever 18 which can protrude. A hole 23 is provided. The lock lever 18 is always resiliently urged by a torsion coil spring (not shown) wound around the support shaft 19 in a direction in which the engaging projection 20 at the front end thereof enters the engaged hole 23. When the slide panel 3 is closed, as shown in FIG. 2, the engagement projections 20 protrude into the engaged holes 23, and the locked state that regulates the forward and backward movement of the slide panel 3 is maintained. ing. In this state, the lower edges of the side plates 11 do not apply a pressing force to the pressing protrusion 21 of the lock lever 18. One end of a known push / pull cable 24 is connected to the outer surface of the rear slider 15 (see FIGS. 3 and 5). This push / pull cable 2
4 is driven by an electric motor (not shown) to move the rear slider 15 in the front-rear direction, thereby causing the slide panel 3 to perform a tilting motion and an opening / closing motion. The guide rail 17 which slidably supports the front and rear sliders 12 and 15 has a pair of guide grooves 31a and 3 whose open surfaces are opposed to each other and which has a U-shaped cross section.
1b, and a C-shaped cable guide 32 whose cross-sectional shape is open above the outer guide groove 31a (see FIG. 5). The rear slider 15 is provided with these guide grooves 3
1a and 31b are provided with laterally protruding portions 33a and 33b. Slide shoes 34a and 34b made of a synthetic resin material having a low coefficient of friction and hard to wear are fitted to these convex portions 33a and 33b. When the slide panel 3 is tilted up, the rear slider 15 is pushed forward by the push / pull cable 24 to be driven. Then, as shown in FIG. 3, the pin shaft 16 of the rear slider 15 moves forward on the forwardly inclined portion of the cam groove 14, raises the rear ends of both side plates 11, and moves from the pressing projection 21 of the lock lever 18. Side plate 1
1 apart. As a result, the lock lever 18 maintains the state in which the engagement protrusion 20 is protruded into the engagement hole 23, and thus the rear end of the slide panel 3 is raised in the locked state in which the longitudinal movement is restricted. When the slide panel 3 is opened, the rear slider 15 is pulled rearward by the push / pull cable 24. Then, as shown in FIG. 4, the pin shaft 16 of the rear slider 15 moves rearward on the upwardly inclined portion of the cam groove 14 and lowers the rear ends of both side plates 11. Thus, the slide panel 3 is first lifted down.
By this lift-down operation, the pressing projection 21 at the rear end of the lock lever 18 is pushed down by the lower edge of the side plate 11, and the engaging projection 20 at the front end comes out of the engaged hole 23.
The slide panel 3 is in an unlocked state in which it can be moved forward and backward. If the rear slider 15 is pulled and driven as it is, the slide panel 3 is housed in a housing portion defined between the lower surface of the fixed roof 1 and the upper surface of the inner frame supporting the guide rail 17. Push / pull cable 24 as described above
When the rear slider 15 stops at the tilt-up limit, which is the movement limit in the pushing direction, the deflection of the push / pull cable 24 becomes excessive due to the overrun of the motor, and the cable guide becomes excessively large. In some cases, a repelling sound was emitted when the inner peripheral surface of the P. 32 was hit. Since the generation of such a popping sound impairs the texture of the vehicle, in the present invention, as shown in FIG. 6, the cable guide 32 on the push operation limit side of the push / pull cable 24 is used.
A cushioning member 35 made of an elastomer material is provided inside the push / pull cable 24 defined by the front end of the cam groove 14.
The rear slider 15
The end of the push / pull cable 24 abuts on the cushioning member 35 before. As a result, before the rear slider 15 stops, the distal end of the push / pull cable 24 comes into contact with the buffer member 35, and the amount of bending of the push / pull cable 24 increases slowly, so that the sound is repelled. Is suppressed. As described above, according to the present invention, before the slide panel stops, the tip of the push / pull cable comes into contact with the cushioning member, thereby suppressing the generation of the repelling sound. A great effect can be achieved in improving the texture.
