On the other hand, the fixing holder 18 is formed in a substantially cylindrical shape having an outer peripheral surface 18a aligned with the inner hole 16b so that it can be fitted into the inner hole 16b of the base end portion 16a of the stay portion 16, and FIG. As shown in FIGS. 4A and 4B, a stepped portion 21 to which the locking hook 19 can be engaged is formed over substantially the entire circumference when they are fitted together (see FIG. 4A). As shown in FIG. 4A, the step portion 21 is stepped inward from the outer peripheral surface 18a of the fixing holder 18 and is arranged at a position where it overlaps with the locking hook 19 in the insertion direction of the fixing holder 18. Thus, the locking hook 19 projecting inwardly of the base end portion 16 a is engaged with the stepped portion 21 exactly.

  Further, as shown in FIG. 4 (A) or the like, the outer peripheral surface 18a which is a side surface of the fixing holder 18 extends over the entire circumference in a direction orthogonal to the insertion direction (FIG. 4 (A), arrow Y). A plurality of ribs 22 are provided intermittently. In this example, a plurality of rows or a plurality of steps of ribs 22 are formed along the insertion direction of the fixing holder 18, and appropriately protrude from the outer peripheral surface 18 a of the fixing holder 18. The rib 22 directly contacts the inner peripheral surface of the inner hole 16b of the base end portion 16a. Further, as shown in FIG. 4A and the like, a taper 23 that is tapered toward the front end side is attached to the front end side of the fixing holder 18 in the insertion direction. In this example, the front end side of the fixing holder 18 to which the taper 23 is attached has four faces, and the faces facing each other among them are tapered as shown in FIGS.

  Further, as shown in FIGS. 3 and 4, the outer periphery of the base end portion 16 a of the stay portion 16 is formed so as to be inserted into the opening 120 of the mounting portion 112 </ b> A over the entire periphery. Insertion ribs 24, 24 'are provided. An engagement groove 25 for the opening 120 is formed between the inner surfaces of the insertion rib 24 and the insertion rib 24 ′. The engagement groove 25 has a groove width that is substantially the same (or moderately small) as the plate thickness of the attachment portion 112 </ b> A that forms the opening 120. When the base end portion 16 a of the stay portion 16 is inserted into the opening 120 of the attachment portion 112 </ b> A, the inner peripheral edge of the opening 120 is engaged with the engagement groove 25. Of the insertion ribs 24, 24 ′, the insertion rib 24 ′ is partitioned similarly to the adjacent locking hook 19 by the plurality of slits 20 (see FIG. 4 etc.).

  Further, among the plurality of slits 20 provided in the base end portion 16a of the stay portion 16, in the present embodiment, as shown in FIG. 4A, it is preferably fixed to a pair of slits 20A that are disposed opposite to each other in the front-rear direction. The holder 18 is engaged. Here, as shown in FIG. 4 and the like, the fixing holder 18 has a pair of front and rear knob portions 26 protruding in the right direction in this example. As described above, when the fixing holder 18 is inserted into the base end portion 16a of the stay portion 16 from the inside of the mounting portion 112A, the knob portion 26 is picked so that the work can be performed. By inserting the fixing holder 18, the base portion 26a of the knob portion 26 is engaged with the front and rear slits 20A.

In this case, referring to FIGS. 5 and 6, the slit width W (FIG. 6) of the slit 20 </ b> A is formed wider than the slit width w (FIG. 5) of the other slits 20. The slit width W of the slit 20A is set to be the same as the width (plate thickness) of the base portion 26a of the knob portion 26.
Further, the slit depth D (FIG. 6) of the slit 20 </ b> A is formed deeper than the slit depth d (FIG. 5) of the other slits 20. In this case, as shown in FIG. 6, the slit 20 </ b> A is deeply formed to the insertion rib 24 on the deep side in the engaging direction of the knob portion 26.

  In the above case, a lead wire 27 for power supply (see FIG. 2B) is connected to the valve 14. The lead wire 27 passes through the stay portion 16 and is fixed to the stay portion 16. It is pulled out from the opening 18b (FIG. 4B) of the holder 18 for use. Thereafter, as shown in FIG. 2B, the lead wire 27 is routed around a suitable position on the back side of the rear fender 112 and connected to an electric circuit configured on the vehicle body side. In that case, the lead wire 27 is guided by being passed through the inside of the substantially ring-shaped knob portion 26, and thus the knob portion 26 has a function of holding the lead wire 27 and restricting the direction of the lead wire 27. To contribute to convenience.

  The winker mounting structure of the present invention is configured as described above. Next, its characteristic operation effects and the like will be described. First, the base end portion 16 a of the stay portion 16 integrated with the winker lamp body 11 is inserted into the opening portion 120 of the attachment portion 112 </ b> A of the rear fender 112. Next, the fixing holder 18 is inserted into the base end portion 16a from the inside of the attachment portion 112A. At this time, the knob portion 26 can be grasped and the insertion operation can be performed easily and accurately. As shown in FIG. 4A and the like, the knob portion 26 has a rib shape in which the outer peripheral portion protrudes outward. That is, the knob portion 26 has a T-shaped cross-sectional shape, so that the fixing holder 18 can be easily attached and detached. It becomes the shape to do.

  Particularly in the present invention, when the fixing holder 18 is fitted into the inner hole 16b of the base end portion 16a of the stay portion 16, as shown in FIG. Since the locking hooks 19 are disposed so as to overlap each other, the locking hooks 19 on the side of the stay portion 16 are accurately engaged with the step portion 21 of the fixing holder 18. Thereby, the stay part 16 attached to the opening part 120 of the attachment part 112 </ b> A can be fixed with an appropriate and high holding force by the fixing holder 18. In this case, since the locking hook 19 is formed substantially over the entire circumference, it has a reliable holding shape, and the function of preventing the drop by the fixing holder 18 is greatly improved. Thus, since the winker lamp body 11, that is, the winker 10 can be accurately fixed to a predetermined portion of the rear fender 112, the winker 10 is always attached even when vibration or the like acts around the rear fender 112 in actual use of the motorcycle 100. It can be held properly and high safety can be ensured.

  Here, when the base end portion 16a of the stay portion 16 is inserted into the opening portion 120 of the attachment portion 112A of the rear fender 112, the base end portion 16a is inserted into the opening portion 120 while being narrowed and deformed. In this case, in this example, a pair of wide slits 20A are provided in the front-rear direction at the base end portion 16a, and the slits 20A are deeply formed to the insertion ribs 24 on the deep side in the engaging direction. Thereby, the base end part 16a side of the stay part 16 can be easily bent and can be easily inserted into the opening part 120, and the assembling property is improved. The inner peripheral edge of the opening 120 is accurately engaged with the engagement groove 25 between the insertion ribs 24 and 24 ′, and is engaged with the insertion ribs 24 and 24 ′. After the proximal end portion 16a side is inserted into the opening 120, the engaged state can be maintained.

  Further, since the tapered taper 23 is provided on the front end side of the fixing holder 18, the taper 23 serves as a guide when the fixing holder 18 is inserted. Accordingly, the fixing holder 18 can be easily inserted even from the inside of the mounting portion 112A having a relatively small space, which contributes to an improvement in assembling property. The fixing holder 18 can be inserted easily and accurately by picking the knob 26, and the assembling property is improved in this respect as well. In the present invention, unlike the shape of Patent Document 1, since there is no locking projection at the tip of the fixing holder 18, the insertion load is uniform and the load is not high.

  In the step of inserting the fixing holder 18, the portion of the outer peripheral surface 18 a is inserted next to the taper 23 portion, and ribs 22 are formed on the outer peripheral surface 18 a in a direction orthogonal to the insertion direction. These ribs 22 are in direct contact with the inner peripheral surface of the inner hole 16b of the base end portion 16a, and slipping when the fixing holder 18 is inserted into the stay portion 16 is improved, so that the assembling property is improved. That is, if the ribs 22 are not provided, the inner peripheral surface of the inner hole 16b of the base end portion 16a and the outer peripheral surface 18a of the fixing holder 18 are brought into full contact with each other, and the frictional resistance in this case is remarkably increased. In the present invention, the ribs 22 are provided to improve the slipperiness of the fixing holder 18 and greatly improve the assemblability.

  When the fixing holder 18 is inserted, the base portion 26a of the knob portion 26 engages with the slit 20A. In this case, as described above, the slit 20A is formed so that the slit width W and the slit depth D are wide and deep, and further, the slit width W is made equal to the width of the base portion 26a of the knob portion 26. In this respect as well, positioning is performed at the time of assembling the members, and assemblability and work reliability are improved.

  On the other hand, by pulling out the fixing holder 18 from the base end portion 16 a of the stay portion 16, the winker lamp main body 11, that is, the winker 10 can be removed from the mounting portion 112 </ b> A of the rear fender 112. At this time, the fixing holder 18 or the slit 20A contributes to the improvement of work.

As mentioned above, although this invention was demonstrated with various embodiment, this invention is not limited only to these embodiment, A change etc. are possible within the scope of the present invention.
For example, the present invention can be applied to the winkers 10 disposed on the left and right sides of the headlamp 119, and the same effects as those of the above embodiment can be obtained.
