The bracket 36 that is used to support the V body of the small motorcycle type vehicle is to be supported in a manner that can swing in the front and rear direction by a laterally protruding pivot 38 at the rear end of a disc-shaped bracket bracket 37, and the above-mentioned disc-shaped bracket bracket 37 is welded on the vehicle body. On the middle cross member 5 of the frame F. The bracket 36 includes: a bracket cover 39 supported by a pivot 38 and a bracket body 40 welded on the rear surface of the bracket cover 39 . By the elastic force of the toggle spring 41 stretched between the bracket 36 and the bracket bracket 37, the bracket 36 is actuated and stably stopped at the folded position shown in FIG. 1 and the erected position shown in FIG. 7 . The stand is restrained in the erect position by the front of the stand cover 39 coming into contact with the rear wall of the stand holder 37 .

Reinforcing members 42, 43 are welded to the rear inner surface of the bracket bracket 37 and the back side of the bracket cover 39 respectively. When the support 36 was in the upright state, then the reinforcement 42, the support bracket 37, the bracket cover 39 and the reinforcement 43 were in overlapping positions in the front and rear directions. The bracket cover 39 and the long cutout 45 of the reinforcement 43 are in positions facing each other. A base plate 46 is fixedly installed in the support bracket 37 with a screw 47, and the finger-like protrusion 46 ₁ (see FIG. 8 ) at the rear end of the base plate 46 is matched with the groove 42 ₁ (see FIG. 9 ) on the reinforcing member 42 Then the base plate 46 stops rotating.

A cam plate 48 is pivotally supported on the upper surface of base plate 46 by bolts 49 . A spring 50 is arranged between the spring hook 481 on the cam plate ₄₈ and the spring hook 462 on the base plate 46, the elastic force of the spring ₅₀ will give the cam plate 48 a clockwise direction as shown in Figure 9, as shown in Figure 9 As shown by the dashed line in the middle, the cam plate 48 stops at an unlocked position where the brake head 48 ₂ on the cam plate 48 and the bracket 46 ₂ on the bottom plate 46 are on top. When the cam plate 48 is in the unlocked position, the cam plate 48 disengages from the bracket cover 39 and the long cutout 45 of the reinforcing member 43, allowing the bracket 36 to swing.

The storage box 21 covered by the lockable seat 20 is provided with a lever 51 that can rotate the cam plate 48 between the locked position and the unlocked position, which can prevent the motorcycle from being stolen. The steel wire sleeve stay cable 52 that connects control bar 51 and cam plate 48 is made of sleeve pipe 53 and interior steel wire 54, and one end of above-mentioned sleeve pipe 53 is fixed on the bracket ₄₆₃ of base plate 46, and one end of interior steel wire 54 is connected with cam. The spring hook ₄₈₁ of the plate 48 is connected. When the inner steel wire 54 is pulled, and the cam plate 48 overcomes the elastic force of the spring 50 and rotates counterclockwise as shown in FIG. 36.

As can be seen from FIGS. 7 and 10 , the control rod 51 pivotally supported on the rear wall of the storage box 21 with the pin 55 can swing within its left and right lateral swing range, which is limited by the upper surface of the bracket 57 . Restricted by the guide ₅₇₁ , the above-mentioned bracket 57 is fixed on the storage box 21 with screws 56, 56. Extending rearwardly through the glove box 21 is a pin 55 having a rear end at which an arm 58 is secured, the arm 58 being connected to the inner wire 54 of the wire sleeve cable 52 .

When the control lever 51 is operated at the position of the solid line in Figure 10, the inner steel wire 54 is subjected to tension, and at the same time overcomes the elastic force of the spring 50, so that the cam plate 48 is rotated to the position of the solid line shown in Figure 9, and the support 36 is locked in the vertical position simultaneously. starting position. At this time, the connecting point a between the arm 58 and the inner wire 54 moves upward beyond the center of the pin 55 which becomes the dead point b, and the lever 51 is stably stopped at the solid line position. On the contrary, if the control lever 51 is operated at the dot-dash line position in Fig. 10, the inner steel wire 54 is slackened, and under the elastic force of the spring 50, the cam plate 48 rotates to the dot-dash line position in Fig. 9, so the bracket 36 is unlocked. At this time, since the coupling point C between the arm 58 and the inner wire 54 moves toward the lower side beyond the dead point b, the lever 51 is stably stopped at the dotted line position.

As mentioned above because it is not the elastic force of the spring 50, but the inner steel wire 54 of the steel wire sleeve cable 52 is pulled by the operating force of the control lever 51 to make the cam plate 48 rotate along the direction of locking it, so even in the pivot of the bracket 36 If there is mud or the like near the bearing part, the cam plate 48 can be reliably engaged with the notch 45 to lock the bracket 36 by operating the control lever 51 vigorously.

The stopper 65 ₂ leans against the stopper 21 ₅ of the storage box 21, and then the pin 66 is rotated in the direction indicated by the arrow A, and the two pin joint protruding fingers 65 ₄ , 65 ₄ are engaged while making them elastically deform left and right. Between, it is preferable to keep the pins in contact with the pin-engaging projections ₆₅₃ of the remaining ten. In this state, when the driver's seat 20 is turned to the closed position _shown by the solid line in FIG. The lock 66 is rotated in the direction of the arrow B and cannot be disengaged from the pin engagement fingers 65 ₃ , 65 ₄ , 65 ₄ .

When the driver's seat 20 is locked in the closed position, it is impossible to pull out the above-mentioned pin 66. Therefore, any articles and clothing in the storage box 21 can be prevented from being stolen, and the locks located in the storage box 21 cannot be operated. The control lever 51 opens the bracket 36, thereby preventing the motorcycle from being stolen.
