[Prior art]

 An X-arm type window regulator for raising and lowering a window glass of an automobile door is known. This window regulator has an X-arm mechanism in which the middle part of the main arm and the sub-arm are rotatably connected via a support shaft, and the middle part between one end of the main arm (movable plate member) and the support shaft is hinged. It is rotatably attached to the base plate (fixed plate member) fixed to the automobile door through the device.

Conventionally, in this type of hinge device, a cylindrical bearing flange portion into which a shaft member is inserted is integrally formed on a base plate by press molding, and a supporting shaft (shaft member) is inserted from the tip end side of this bearing flange portion. After that, the main arm was fixed to the tip of the support shaft by caulking. In this case, grease is applied at the time of assembly to prevent wear of the hinge device and maintain smooth rotation. As a result, the main arm is rotatably supported by the base plate via the support shaft.

[0004]

[Problems to be solved by the device]

 However, in the conventional hinge device described above, since the tip of the support shaft is crimped during assembly, the grease existing between the base plate and the main arm diffuses to an unnecessary portion during caulking, resulting in hinges. There was a problem that caused insufficient grease in the device.

In order to solve this problem, in other technical fields, a hinge device provided with a recess for storing grease is also known, for example, from Japanese Patent Publication No. 35-15610, but the conventional hinge device is In all cases, it is necessary to cut and form the constituent members, and therefore, processing during manufacturing is not easy, and there is a problem that costs are increased.

The present invention has solved the problems existing in such conventional techniques, and an object of the present invention is to provide a hinge device for an automobile, which can reduce the cost at the time of manufacturing by facilitating the processing.

[Embodiments] Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, a schematic configuration of a window regulator including the hinge device 1 according to the present embodiment will be described with reference to FIG.

R is a window regulator built in the door of the automobile, and includes an X arm mechanism 10. The X-arm mechanism 10 includes a main arm 11 that constitutes the movable plate member 3 and a sub-arm 12. An intermediate portion between the main arm 11 and the sub-arm 12 is rotatably coupled by a support shaft 13. The sub arm 12 is divided into two parts, which are arranged on the front and back sides of the main arm 11. A sector gear 14 is fixed to one end of the main arm 11.

On the other hand, 15 is a base plate that constitutes the fixed plate member 2, and is fixed to the automobile door. An intermediate portion of the main arm 11 between the sector gear 14 and the support shaft 13 is rotatably attached to the base plate 15 via the hinge device 1 according to this embodiment. In addition, an operating portion 16 is provided at another position on the base plate 15. The operation unit 16 is provided with a pinion 18 which is rotated by operating the handle 17, and the pinion 18 meshes with the sector gear 14.

On the other hand, the other end of the main arm 11 and one end of the sub-arm 12 are slidably mounted on a movable rail 21 which can be raised and lowered, respectively, and the other end of the sub-arm 12 is fixed to a fixed rail 22 fixed to an automobile door. It is slidably loaded. Note that W indicates a window glass connected to the movable rail 21.

Therefore, when the handle 17 of the operation unit 16 is rotated, the sector gear 14 is displaced in the vertical direction via the pinion 18. As a result, the main arm 11 is rotationally displaced about the hinge device 1 as a fulcrum, the other end of the main arm 11 moves up and down, and the movable rail 21 and the window glass W also move up and down.

Next, the configuration of the hinge device 1 according to this embodiment will be specifically described with reference to FIGS. 1 to 3.

First, a cylindrical bearing flange portion 5 as shown in FIGS. 2 and 3 is integrally formed on the base plate 15 by press molding or the like. Further, a concave portion 6 for accommodating grease is formed on the root side of the bearing flange portion 5. In this case, the concave portion 6 can be formed together with the bearing flange portion 5 by press molding or the like. Specifically, the diameter of the bearing flange portion 5 on the root side is larger than that of the other portion, that is, it can be easily formed by providing a step, whereby the bearing flange portion 5 extends along the circumferential direction. A ring-shaped recess 6 is formed. In addition, the base plate 15 is integrally formed with a convex portion 31 for reducing a sliding surface with respect to the main arm 11, and a hook portion 32 protruding at a right angle for stopping one end of a spring described later.

After that, the mounting hole 36 of the main arm 11 is fitted into the fixing portion 35, the washer 37 is fitted into the tip of the fixing portion 35, and then the tip of the mounting hole 36 is caulked 38. Thus, the hinge device 1 is configured, and the main arm 11 is rotationally displaced integrally with the shaft member 4 with respect to the fixed base plate 15. Further, as shown in FIGS. 1 and 3, a spiral spring 39 is installed between the hook portion 32 and the hook portion 33. The spiral spring 39 functions as a balancer when the window glass W is moved up and down.

According to the hinge device 1 as described above, the recess 6 can be integrally formed with the bearing flange 5, so that the recess 6 can be easily machined and the manufacturing cost can be reduced. Further, since the grease is stored in the concave portion 6, a necessary and sufficient amount of grease can be secured, and the grease can be provided from the concave portion 6 to the peripheral surface of the shaft member 4 and further between the fixed plate member 2 and the movable plate member 3.
