Fig. 5 is a perspective view of the present invention. Of vehicle wheel speed detection sensor protection structure

The protection plate 51 is such that the lower end 52b of the protective body portion 52 is more prominent than the wheel speed = the lower end 40a of the sensor 40, and the lower portion 52b is provided with a bend toward the wheel speed detection sensor 40 side. Lower bend portion 55, lower bend portion] ^ The screw hole 55a and the slightly lower central portion 52c of the protective body portion 52 are provided with a central bend portion 56 that bends to the opposite sides of the two speed detection sensors 40. The central bent portion 56 forms a bolt hole 56a, and a slightly central upper portion of the protective body portion 52 is provided with a bent portion 53 bent toward the wheel speed detection sensor 40 side. On the side of the wheel speed detection sensor 40, the bend is slightly Π, <'', the upper end 52 &amp; the lower part extends the foot 54 to the gear box, and the front end 42a of the foot 54 is provided with a bending piece 54a. . When installing the protection plate 51, set the wheel speed detection sensor I 0 in the gear box 23, then set the protection plate 51 at the position shown by the imaginary line, insert the i-th bolt π into the bolt hole 55a, and insert the wheel speed detection sensor at the same time. In the mounting hole (not shown) of the tester 40, the second bolt 45b is inserted into the bolt hole 56a. Next, the first and second bolts 4 5 a, (not shown). The device 40 is fixed to the gear box 23 by tightening the first bolt 45. 45b is screwed into the bolt hole a ′ of the gear box 23 to detect the wheel speed

By using the first bolt 45a, the wheel speed detection sensor * and the retaining plate 51 can be tightened together, and the wheel speed detection sensor 40 can be saved. Bolting is used. "Time 0" = This, by using the first 1. The second bolts 45a and 45b attach the protection plate 51 to the gear box 23, so that the bending piece 5 of the leg portion 54 can be "abutted" to the gear box μ.

The wheel portion 'covers the side surface 4 3 on the 6 side with the protective body portion 5 2, and at the same time, the bendable portion 53 covers the upper portion 4 1 a of the wheel speed. The wheel speed detection sensor 4 is near the connecting portion 46a of the lead wire 46, and the protruding portion 4 1 of the degree detection sensor 40 is described here. The bent portion 53 covers only the upper portion of the protruding portion 41. "aj The reason is that when the protection of the wheel speed detection sensor 40 is considered, it is better to cover the entire upper side of the protruding portion 41 with the bent portion 53. * = Yes, if the entire upper side of the protruding portion 41 is covered, in case of bending Part 53 is not easy to remove when the gap between the outlet 41 enters the soil or dust

Invading dirt or dust. Therefore, only the important portion of the protruding portion 41 (i.e., the upper portion 41a) is covered with the bent portion 53, and it is easy to remove the invading dirt or dust. An example of the operation of the sensor protection structure will be described below. Fig. 6 (a) '(b) is an explanatory view of the function of the protective structure of the vehicle speed detection sensor of the present invention. In FIG. 6 (a), a hole 71 formed in the wheel fork 70 of the rear wheel 16 is used to install a U-shaped anti-theft lock 75. This prevents theft of the rear wheel 16 to prevent theft.

Here, in the case where the third person causes the automatic one-wheeler to enter for 10 hours in the state where the anti-theft lock 75 is installed, the rear wheel 16 rotates in the direction of the arrow, and the anti-theft lock 75 and the fork 70 rise simultaneously. In FIG. 6 (b), 'because the lower end 5 2b of the protective body portion 52 of the sensor protection structure 50 protrudes downward only by the protrusion amount L of the lower end 40a of the wheel speed detection sensor 40, the anti-theft The lower end 52b or the bent portion 53 of the protective body portion 52 is contacted by the lock 75. Therefore, the anti-theft lock 75 can be prevented from contacting the wheel speed 8 «

Even if the anti-theft lock is used, the 5th connection_ b is mounted on the tooth with the first bolt 4 5 a. The lock contact with the lower end 52b can also prevent the protective plate 51 from changing the shape of the protective plate 51 to the shape of the protruding portion 41. The wheel speed detection sensor 40 is also a bend detector using the protective plate 51. The upper part of the 40 protruding part 1 is covered with the wheel speed detection bending part 5 3 and the covering protruding part 4 is enlarged. The "effect of the invention" can also be used as a whole. According to the above structure, the present invention exerts the following patent application scope. The first item is to protect the driving wheel of the wheel speed detection sensor; otherwise, the bent portion formed by the J body cover V covering the car curve covers the wheel speed 1 '. j is folded from the protective body portion. The protruded end of the degree detection sensor is constructed so that the protruded end of the speed detection sensor of the protection wheel is simply constituted by only bending the plate ^ It can protect the invention of the second patent application scope of the car from exemption: two = shape, The front end is provided with a foot portion. The foot portion: open cm == can prevent the protection of the body portion :; the shape = curve only suppresses the deviation of the edge retaining plate.
