The teeth 47A and 47B can rotate to a position where the teeth 47A and 47B can be locked to the lock receiving piece 26. Thus, when the main brake pedal 38 is further depressed, the lock teeth 47A, 47B engage with the lock receiving piece 26 at a predetermined position (see FIG. 11.
FIG. 5 shows a state in which the lock teeth 47A on the distal end are engaged with the lock receiving pieces 26. However, when the depression of the main brake pedal 38 is increased, the lock teeth 47B on the proximal end side engage with the lock receiving pieces 26. . ). For this reason, even if the depression operation on the main brake pedal 38 is released, the brake does not return to the released state, and the electric vehicle 1 enters the parking brake state.

Next, the operation when the accelerator is operated while the vehicle is in the parking brake state will be described. When the accelerator pedal 14 is depressed, the accelerator shaft 11 rotates via the accelerator lever 15. Then, the rotation of the accelerator shaft 11 causes the connection groove 16 and the connection portion 31 to rotate.

The brake arm 23 rotates in the direction shown by the arrow F in FIG. By the rotation of the brake arm 23, the lock arm 25 also rotates in the direction of the natural state, and when the lock arm 25 reaches a predetermined position, the lock release projection 4
8 is kicked by the kicking bolt 49 and the interlocking piece 42
Protrudes from the interlocking recess 34. Thus, the brake device 3 returns to the original natural state.

According to this embodiment, since the brake device 3 is formed as a unit via the brake bracket 18, the work of assembling it to the vehicle body is simple. In addition, the work of removing the brake device 3 at the time of maintenance or the like is easy. Further, since the lock device 25 and the release arm 33 are incorporated in the brake device 3, the brake device 3 can be assembled in another place in advance. In comparison, both arms 2
The assembly accuracy between 5, 33 is easily ensured. further,
Since the accelerator shaft 11 and the lock release shaft 30 are connected via the misalignment absorbing portion 36 that absorbs the misalignment between the two shafts, for example, the mounting positions of the brake bracket 18 and the accelerator bracket 7 and the positions of these brackets High accuracy is not required for the mounting position of the members such as the lock release shaft 30 and the accelerator shaft 11, and the mounting performance is improved.
