  Fig.7 (a) is a top view which shows the cover body 89, (b) is a right view of (a). 7 (a) and 7 (b), the cover 89 is formed by press-molding a metal plate material, and a coupler cover 93 is continuously provided via an inclined portion 92 upward from the ECU cover 91. A tip end portion of the coupler cover portion 93 is bent downward to form a coupler retaining piece 94. On the opposite side of the ECU covering portion 91 from the coupler covering portion 93, mounting pieces 97 and 98 are extended from both sides. The right end of the coupler cover 93 shown in FIG. 7 (a) and the tip of the mounting piece 98 are bent upward, as shown in FIG. 7 (b). 102 is formed, and an insertion hole 90 is formed in the attachment portions 101 and 102. An insertion hole 90 is also formed in the left end of the coupler cover 93 and the tip of the mounting piece 97.

  As shown by a two-dot chain line in FIG. 6, lid 89 is placed on the upper surfaces of ECU 68 and couplers 72A and 72B. That is, the cover 89 has two attachment pieces 97 and 98 positioned on both front and rear sides of the relay box 83, and a part of the ECU cover 91 is below the three connection parts 83 a protruding from the main body part of the relay box 83. The tip of the coupler retaining piece 94 is located close to the upper part of the connecting portions 72a and 72b of the couplers 72A and 72B.

Placed on. Accordingly, the rear frame 21 is formed with an insertion hole 103 at a position that matches the right rear mounting hole 90.

  When the lid 89 is arranged in the above-described arrangement, the four locking bolts (one-way bolts) 107 in FIG. 5 are screwed into the rubber nut 88 through the insertion hole 90 of the lid 89. Accordingly, the lid 89 is attached to the rear fender 27. The locking bolt 107 can be rotated only in one direction to be fastened to the rubber nut 88 and cannot be removed by reverse rotation.

  In the electrical component removal preventing structure, the ECU 68 and the couplers 72A and 72B connected thereto can be prevented from being removed. That is, the ECU 68 is covered with the ECU cover portion 91 of the lid 89 that is fixed to the three bosses 69 and the single hook 70 of the rear fender 27, which is a vehicle body constituting member, by the locking bolt 107, and further, Since it is pressed against the bottom wall 58 of the rear fender 27, it is difficult to remove.

  Further, one coupler 72A is prevented from moving in the horizontal direction by a restriction wall 71 formed integrally with the rear fender 27, and access to the coupler 72A is made possible by a coupler retaining piece 94 formed integrally with the lid 89. It is difficult to remove because it is blocked. In general, the ECU 68 can be prevented from being replaced if the removal of the at least one coupler 72A is prevented. However, the other coupler 72B may be similarly provided with a restriction wall to prevent the coupler 72B from being removed.

  Further, the removal preventing structure is different from the existing structure in that the resin rear fender 27 is changed to a shape in which the restriction wall 71, the boss 69, the hook 70, and the locking piece 74 are provided, and the metal lid. Since it is obtained by attaching 89, the cost is not increased as compared with a case where a dedicated electrical box for storing electrical components is separately provided. Further, since the lid 89 separate from the rear fender 27 is provided, the shape does not increase as in the case where the lid and the regulating wall are integrated, and the regulating wall 71 is made of a resin mold. Since it is integrally formed with the rear fender 27, which is a molded product, it is easy to form a shape with rounded corners, whereby the connecting portions 72a and 72b of the couplers 72A and 72B hit the corners of the regulating wall 71 and wear. Is prevented.

  The lid 89 may be attached to the rear frame 21, that is, the vehicle body frame FR. In addition, an electrical component such as the ECU 68 may be attached to the vehicle body frame FR. In this case, the lid 89 is a rear frame 21 that is a part of the vehicle body frame FR or a rear fender that is one of the vehicle body components. 27.

  FIG. 8 is a perspective view showing the electrical equipment removal preventing structure according to the second embodiment of the present invention. This embodiment is provided with a double locking device for the seat, and a rear fender 109 is combined and fixed to each other inside the rear frame 108 in substantially the same manner as in the first embodiment, and the rear frame 108 is spaced apart in the front-rear direction. A front seat lock mechanism 112 and a rear seat lock mechanism 113 are provided on the front cross member 110 and the rear cross member portion 111, respectively, which are provided so as to extend in the left-right direction. The front seat lock mechanism 112 and the rear seat lock mechanism 113 are operated via the two operation cables 117 by the key operation of the key device 114.

  On the bottom wall 115 of the rear fender 109, four bosses 118 are formed at positions on the rear side of the front seat lock mechanism 112, and the mounting holes of the bosses 118 are the same as those used in the first embodiment. After the rubber nut 88 (FIG. 5) is fitted, the tool box 119 indicated by a two-dot chain line, which is an example of a vehicle component, is the same as the rubber nut 88 (FIG. 5) of the locking bolt 107 (FIG. 5) used in the first embodiment. It is fixed so as not to be removed by screwing to FIG. On the other hand, as shown in the plan view of FIG. 9, the rear fender 109 includes an ECU 68 and a relay box 83 on the front side of the rear seat lock mechanism 113 and on the rear side of the tool box 119, as in the first embodiment.

As described above, the tool box 119 is fixed to the boss 118 of the rear fender 109 by the screwing of the locking nut 107 as described above. Since it is close to the upper side of 72B, access to the couplers 72A and 72B located below the tool box 119 is blocked, so that it is difficult to remove the couplers 72A and 72B. Therefore, replacement of the ECU 68 can be prevented. On the other hand, the portion of the ECU 68 opposite to the couplers 72A and 72B is adjacent to the lower portion of the rear cross member 111 of the rear frame 108 constituting the rear half of the vehicle body frame with the relay box 83 interposed therebetween. Since the ECU 68 cannot be lifted because the cross member 111 is in the way, the replacement of the ECU 68 is more effectively prevented.

  The detachment preventing structure of this embodiment secures the disposition position of the couplers 72A and 72B below the tool box 119 only by providing four bosses 118 for supporting the tool box 119 at a required position of the rear fender 109. In addition, the structure of the ECU 68 can be simplified because it is only necessary to change the mounting position so that the portion of the ECU 68 opposite to the couplers 72A and 72B is positioned below the rear cross member 111 of the rear frame 108. The cost is not high.

  The tool box 119, which is an example of the vehicle accessory, may be attached to the rear frame 108, that is, the vehicle body frame FR. In addition, an electrical component such as the ECU 68 may be attached to the vehicle body frame FR. In this case, the vehicle component such as the tool box 119 is a rear frame 108 that is a part of the vehicle body frame FR, or a vehicle body component. It is attached to the rear fender 109 which is one of the above.

  The present invention can be applied not only to motorcycles but also to tricycles and rough terrain vehicles.
