Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a front fork mounting device suitable for mounting a mudguard fan on a front fork of a motorcycle or the like.

[0002]

[Prior Art]

 As shown in FIG. 5, a conventional attachment device of this type has a pair of outer tubes a, which are attached to the wheel side, into which an inner tube b attached to the vehicle body is slidably inserted. A pendant mounting boss c provided with two bolt holes c1 is assembled, and a ender e is mounted on the ender mounting boss c by using a bolt d.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional technique has a problem that the outer tube a is complicated in shape processing because the outer tube a has the structure for assembling the boss mounting boss c.

[0007] Fender e is assembled using a total of four bolts d on the left and right, so that there is a problem that it takes time to attach.

Further, there is a problem in that the outer tube a and the fan e are not positioned, and that the fan e must be supported by a hand and positioned before mounting when assembling.

Therefore, the present invention has been devised in view of the problems of the above-described conventional techniques, and an object thereof is to provide a front fork attachment device for improving the workability of the outer tube and the assembling property of the front tube. I am trying.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the front fork attachment device of the present invention, an inner tube attached to the vehicle body side is slidably inserted into a pair of outer tubes that are attached to the outer tube. In the front fork attachment device of the attached front fork, a protrusion or groove is provided in the circumferential direction on the upper part of the outer tube, and on both sides of the main body of the fander, a groove for engaging the above-mentioned protrusion or groove on the inner peripheral surface. Or, provide a convex part and extend a holding part that winds the upper part of the outer tube through a gap and tighten the end part of the holding part and the joint part of the opposing body with a bolt to attach the fender. It is characterized by

[0008]

[Action]

 Place the upper part of the outer tube inside the holding part, and at the same time engage the groove or the convex part of the holding part with the convex part or groove of the outer tube, and further align the end part of the holding part and the joint part of the main body, Tighten each with one bolt and assemble the ender between the pair of outer tubes.

[0009]

【Example】

 An embodiment will be described with reference to FIGS. 1 to 5. According to the present invention, a fan 3 is provided between a pair of outer tubes 1 mounted on a wheel side into which an inner tube 2 mounted on the vehicle body is slidably inserted. It is related to the front fork to which it is attached.

The inner tube 2 is connected to the vehicle body side via an upper bracket and an inner bracket (both not shown), and the outer tube 1 is connected to the axle via a bracket (not shown).

The upper portion 13 of the outer tube 1 is formed to have a large diameter, and the upper portion 13 is circumferentially formed with an annular convex portion 11 as shown in FIGS. 2 and 3 or an annular groove 12 as shown in FIG. Has been formed.

The fender 3 is composed of a main body 32 having a shape along the tire, and a holding portion 31 extending on both sides of the main body 32 with a gap 36 between the main body 32 and the upper tube. There is.

As shown in FIGS. 2 and 3, the holding portion 31 is formed in such a shape that the gap 36 is located substantially at the center line position of the outer tube 1, and the end portion 35 of the holding portion 31 contacts the main body 32. The joint portion 39 is formed in an overhanging shape, or the holding portion 31 is formed in a shape in which the end portion 35 reaches close to the side portion of the main body 32 as shown in FIGS.

A groove 33 or a convex portion 34 that engages with the convex portion 11 or the groove 12 is provided on the inner peripheral surface of the holding portion 31, a bolt hole 37 is provided at an end portion 35, and the end portion 35 is Bolt holes 38 are also provided in the joint portions 39 of the main body 32 facing each other so as to correspond to the bolt holes 37.

The end portion 35 and the joint portion are fastened with a bolt 4, and the ender 3 is fixed between the pair of outer tubes 1.

[0016]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

A. The outer tube is easy to process because it only needs to process the grooves or protrusions.

B. As the assembly of the Fender to the outer tube can be done with only one bolt on each of the left and right sides, the assembly work can be done in a short time and the work can be done easily.

C. At the time of assembling the fender, the groove or the convex part of the holding part is tightly engaged with the convex part or the groove of the outer tube for positioning, and the assembling is easy, and the fender does not move in the vertical direction.
