As shown in FIG. 5, the engaging portion 60 is located on the inner side (right side) of the vehicle body with respect to the valve 35 (or the socket 34) attached to the bending portion 33 in the attached state. Furthermore, as shown in FIG. 7, the engaging portion 60 is located in front of the valve 35 attached to the bending portion 33 in the attached state. That is, the engaging portion 60 is located at a place where it is difficult to insert the tool by the bulging curved portion 33.

Specifically, the engaging part 60 has a hook part 20 provided on the front leg shield 10 and a receiving part 40 provided on the turn signal lamp unit 30.
First, the hook part 20 is demonstrated with reference to FIG.4, FIG.8, FIG.9. FIG. 8 is a view of the hook portion 20 as viewed from the arrow direction A shown in FIG. FIG. 9 is a view showing a state before the hook portion 20 and the receiving portion 40 are engaged, and is a cross-sectional view seen from the same direction as FIG. The receiving part 40 of the turn signal lamp unit 30 shown in FIG. 9 shows a state before being rotated by 90 °.

As shown in FIG. 4, the hook portion 20 is provided so as to protrude from the back side of the front leg shield 10 at a position close to the tip portion 13 in the periphery of the attachment portion 14.
As shown in FIGS. 8 and 9, the hook portion 20 is formed in a plate shape and has a base end portion 21, a support portion 23, a bent portion 24, and a distal end portion 25. The base end portion 21 is formed so as to protrude from the back side of the front leg shield 10 toward the vehicle body inner side (right side) and rear side. The base end portion 21 is formed with a support plane 22 extending in the left-right direction and extending in the up-down direction. The support plane 22 abuts on a projection surface 50 of a receiving portion 40 described later in the attached state.

The support portion 23 is formed to protrude from the base end portion 21 toward the rear side. The support part 23 supports the receiving part 40 by engaging with the receiving part 40 in the attached state. The bent portion 24 is formed to be bent in an arc shape from the support portion 23 toward the inside (right side) of the vehicle body by approximately 90 ° while maintaining the plate thickness t of the support portion 23. The center point O of the arc of the bent portion 24 substantially coincides with the rotation center when the turn signal lamp unit 30 is rotated and attached. The distal end portion 25 is formed so as to protrude from the bent portion 24 toward the vehicle body inner side (right side). A support plane 26 parallel to the support plane 22 of the base end portion 21 described above is formed on the front side of the distal end portion 25. The support flat surface 26 comes into contact with a contact surface 49 of the receiving portion 40 described later in the attached state.
The support portion 23, the bent portion 24, and the distal end portion 25 are formed with a groove portion 27 extending outside the vehicle body of the support portion 23, on the outer side of the bent portion 24, and on the rear side of the distal end portion 25 in order to prevent sink marks during manufacturing. ing. In addition, the plate | board thickness t mentioned above shall mean the plate | board thickness of the location in which the groove part 27 is not formed. Further, in FIG. 9, the width w in the left-right direction is determined by combining the support portion 23, the bent portion 24, and the tip portion 25.

Next, the receiving part 40 is demonstrated with reference to FIG.5, FIG.6, FIG.9.
As shown in FIG. 5, the receiving portion 40 is positioned at a substantially end portion on the tapered side of the housing main body 32 when viewed from the rear side of the vehicle body in the attached state. Here, as shown in FIG. 6, the substantially end portion refers to a corner portion 42 of the housing body 32 that is farthest from the end portion 41 when the tip end of the housing body 32 on the tapered side is the end portion 41. The imaginary line L1 connecting the two points is located on the farthest end 41 side of the bisector center point Q. As shown in FIG. 7, the receiving portion 40 is integrally formed so as to protrude from the outer shape of the housing main body 32 of the turn signal lamp unit 30 to the vehicle body inner side (right side) in the attached state.

  As shown in FIG. 6, the receiving portion 40 is formed with a rectangular slit portion 43 that is long in the vertical direction. The slit portion 43 is formed with a slit width into which the tip portion 25, the bent portion 24, and the support portion 23 of the hook portion 20 described above can be inserted. The slit portion 43 is located on the vehicle body outer side (left side) with respect to the vertical line L <b> 2 that passes through the endmost portion 41.

  As shown in FIG. 9, the slit portion 43 has a first inner surface 45 and a second inner surface 46 that face each other with the space 44 interposed therebetween. The first inner surface 45 is formed in a substantially U-shaped arc shape protruding toward the space 44 side. The first inner surface 45 comes into contact with the inside of the bent portion 24 when the receiving portion 40 is engaged with the hook portion 20. In the present embodiment, the radius of curvature of the first inner surface 45 (the distance from the center point P of the arc of the first inner surface 45 to the first inner surface 45) is the radius of curvature (bent of the bent portion 24). The distance from the center point O of the arc of the portion 24 to the inside of the bent portion 24) is formed so as to substantially coincide.

Further, the second inner side surface 46 is formed with a first plane 47 and a second plane 48 which are inclined and adjacent to each other. The first flat surface 47 is formed on the front leg shield 10 side of the second inner surface 46, and is in the direction (arrow B shown in FIG. 9) in which the slit portion 43 is inserted into the distal end portion 25 of the hook portion 20. It is inclined in the direction in which the slit width widens. Therefore, even when the receiving part 40 is inserted obliquely with respect to the hook part 20, the tip part 25 of the hook part 20 can be easily inserted into the slit part 43.
Here, when a plane parallel to the first plane 47 and in contact with the first inner surface 45 is defined as a first virtual plane Sv, an interval S between the first plane 47 and the first virtual plane Sv is The thickness of the hook portion 20 is set to be equal to or greater than t.

  On the other hand, the second plane 48 is formed in parallel with the direction (arrow B shown in FIG. 9) in which the slit portion 43 is inserted into the tip portion 25 of the hook portion 20. Here, when a plane parallel to the second plane 48 and in contact with the first inner surface 45 is a second virtual plane Uv, an interval U between the second plane 48 and the second virtual plane Uv is The hook portion 20 is set to be equal to or greater than the plate thickness t and smaller than the width w described above. In addition, it is preferable that the space | interval U is a dimension slightly larger than the board thickness t.

  Further, in the attached state, when the side of the receiving part 40 that faces the back side of the front leg shield 10 is the front side and the opposite side is the back side, the back side of the receiving part 40 is connected to the first inner surface 45 described above. A continuous contact surface 49 is formed. The abutment surface 49 abuts on the support plane 26 of the tip 25 in the attached state. Further, a projection surface 50 adjacent to the first flat surface 47 is formed on the front side of the receiving portion 40. The projecting surface 50 abuts on the support plane 22 of the base end portion 21 in the attached state. Here, the distance X between the contact surface 49 and the projection surface 50 is set to be approximately the same as the distance Y between the support plane 22 and the support plane 26.

Next, the fastening part 61 and the fastening part 62 are located on the back side of the front leg shield 10 and in a position where the work is easy, near the rear end of the front leg shield 10. As shown in FIG. 5, in the present embodiment, the fastening portion 61 and the fastening portion 62 are located apart from each other up and down with the attachment portion 14 interposed therebetween.
Specifically, each of the fastening portion 61 and the fastening portion 62 includes a fastening hole 28 provided in the front leg shield 10, an insertion hole 51 provided in the turn signal lamp unit 30, and a fastening member 71 such as a screw. Have.

As shown in FIG. 4, the fastening hole 28 is integrally provided on the back side of the front leg shield 10 at a position close to the rear end that is separated from the front end portion 13 in the periphery of the attachment portion 14. The fastening hole 28 is formed so that the fastening member 71 can be screwed together.
As shown in FIG. 6, the insertion hole 51 is formed in a protruding portion 52 that protrudes in the vertical direction from the outer shape of the housing body 32 of the turn signal lamp unit 30 in the attached state. The insertion hole 51 is formed in a size that allows a part of the fastening member 71 to be inserted.
Therefore, in the fastening part 61 and the fastening part 62, the turn signal lamp unit 30 can be attached to the front leg shield 10 by inserting the fastening member 71 through the insertion hole 51 and fastening it in the fastening hole 28.

Next, a method for attaching the turn signal lamp unit 30 will be described with reference to FIGS. Here, the method for attaching the left turn signal lamp unit 30 will be described, but the method for attaching the right turn signal lamp unit 30 is the same.
First, the operator holds the turn signal lamp unit 30 so that the tip portion 25 of the hook portion 20 and the slit portion 43 face each other. That is, the operator holds the turn signal lamp unit 30 at a position rotated, for example, approximately 90 ° counterclockwise around the center point P with respect to the angle of the turn signal lamp unit 30 after the attachment. Here, the angle that is rotated in advance with respect to the angle after attachment is preferably an angle at which the bent portion 24 of the hook portion 20 is bent.

  The operator moves the turn signal lamp unit 30 and inserts the distal end portion 25 of the hook portion 20 into the slit portion 43. At this time, since the first inner surface 46 of the slit portion 43 is formed with the first flat surface 47 that is inclined in the direction in which the slit width is widened with respect to the arrow B direction, the distal end portion 25 can be easily inserted into the slit portion. 43 can be inserted. In addition, by forming the first flat surface 47, the angle rotated in advance with respect to the angle of the turn signal lamp unit 30 after mounting is set to be smaller than the angle at which the bent portion 24 bends. Even in this case, the distal end portion 25 can be inserted into the slit portion 43. Therefore, it becomes possible to assemble with a smaller rotation angle, and a required space is small, and workability when the turn signal lamp unit 30 is attached to and detached from the hook portion 20 can be improved.

  The operator rotates the turn signal lamp unit 30 clockwise from the state in which the distal end portion 25 of the hook portion 20 is inserted into the slit portion 43, so that the slit portion 43 moves to the bent portion 24. At this time, as shown in FIG. 10, the first inner side surface 45 of the slit portion 43 and the inside of the bent portion 24 rotate while being in contact with each other. As described above, the curvature radius of the first inner surface 45 and the curvature radius inside the bent portion 24 substantially coincide with each other. Accordingly, the turn signal lamp unit 30 has the center point P and the center point O as the rotation centers in a state where the center point P of the arc of the first inner surface 45 and the center point O of the arc of the bent portion 24 substantially overlap each other. It rotates with respect to the front leg shield 10.

The operator further rotates the turn signal lamp unit 30 clockwise to move the slit portion 43 to the support portion 23, and the turn signal lamp unit 30 is moved to the front leg shield by the engaging portion 60 as shown in FIG. 10 is engaged.
Here, for example, in order to slide the turn signal lamp unit 30 into engagement with the slit portion 43 as in the prior art, for example, the slit width (the interval U between the second plane 48 and the second virtual plane Uv). However, the width w in the left-right direction including the support portion 23, the bent portion 24, and the distal end portion 25 is required. Accordingly, a gap is generated between the slit portion 43 and the hook portion 20 when engaged. In this embodiment, the turn signal lamp unit 30 is rotated and engaged with the front leg shield 10, whereby the slit width U of the slit portion 43 can be made substantially the same as the plate thickness t of the hook portion 20. A gap between the portion 43 and the hook portion 20 can be reduced. That is, as shown in FIG. 11, the first inner side surface 45 is restricted by the support portion 23 and the bent portion 24, and the second inner side surface 46 of the slit portion 43 is restricted by the support portion 23. The backlash of the receiving part 40 in the part 60 can be prevented. Moreover, since the slit width U of the slit part 43 can be minimized, the hook part 20 and the receiving part 40 can be made small, so that the size of the engaging part 60 can be reduced.

Further, as shown in FIG. 11, the contact surface 49 of the receiving portion 40 contacts the support plane 26 of the distal end portion 25, and the projection surface 50 of the receiving portion 40 contacts the support plane 22 of the base end portion 21. Therefore, in the engaging part 60, since the receiving part 40 is regulated at a plurality of locations, it is possible to further prevent the receiving part 40 from rattling.
