As is clear from FIG. 2, the lever 9 is rotatably supported on the supporting body 6 side by a support shaft 10, and the lever 9 is fixed to the support shaft 10 at its base. A fan-shaped engaging body 11 protruding in the radial direction is fixed to the support shaft 10, and the engaging body 1
Reference numeral 1 also serves as a regulating member, and the engaging body 11 is in the illustrated position, which indicates a non-operating position of the parking brake. A main switch 12 is located at the rear adjacent to the engaging body 11.
The main switch 12 is provided with a keyway 13, and the keyway 13 is turned off in the horizontal position as shown in the figure.
The diagonally lower right position is the on position, which starts the engine and turns on various electrical systems, and the vertical position, rotated 90 degrees from the off position, is the lock position where the key can be inserted and removed. An engagement pin 14 is provided on the surface of the main switch 11 on the support shaft 10 side, and the pin 14 is connected to the key groove 10.
It advances and protrudes only at the locked position, and retreats at other positions as shown in the figure.

In the embodiment, a gap is provided between the pin 14 and the engagement body 11, and the lower half of the seat lock engagement claw 15 is exposed between the gaps. The engaging pawl 15 is pivotally installed on the support body 6 side via a support shaft 16, and has a pawl portion 15a at the upper tip and is an engaging piece 17 that hangs below the bottom plate of the seat 7.
The figure shows a released state,
The spring 18 urges the counterclockwise direction in the figure, which is the release direction, so that the contact edge 15b on the rear surface of the lower end of the lower half is pressed against the pin 14.
Abutting against the end surface, and the opposite side of the contact edge 15b is the regulating edge 1
5c, and the regulating edge 11a on the outer peripheral edge of the engaging body 11 faces the regulating edge 15c with a small gap maintained therebetween.

Next, to describe its function and effect, in Fig. 2, the main switch 11 is in the OFF state, and by rotating the keyway 13 clockwise, it becomes the ON position, starts the engine, turns on the electrical system, Drive. In the off position, the keyway 13 cannot be removed as described above. The key can be removed from the groove by rotating the key groove 13 counterclockwise and returning it to the locked position, but in the illustrated state where the parking brake lever 9 is in the non-operating position, the key is moved from the off position to the locked position. When trying to rotate the groove, the pin 14 advances to the left in the figure, and the claw 1
5 and press it to the left,
The regulating edge 15c is the regulating edge 11 that the engaging body 11 faces.
a, and the pin 14 is prevented from advancing, that is, the groove cannot be rotated to the locked position. Therefore, the key cannot be removed from the main switch, and the driver is forced to perform the parking operation described below.

When the lever 9 is lifted clockwise upward from the downward B position in FIGS. 1 and 2 to shift to the parking brake operating position, the support shaft 10 rotates in the same direction, and the The engaging body 11 also rotates in the same direction, the fan-shaped engaging portion 11b moves clockwise by a predetermined angle as indicated by the chain line C, and the lower end of the regulating edge 15c of the pawl 15 is released from regulation when the lever 9 is at the operating position A. It happens. When the lever 9 is in the operating position A, the parking brake is activated and the brake is locked. In this state, when the keyway 13 is rotated to the lock position,
The pin 14 advances, the pawl 15 swings clockwise about the support shaft 16, and even if the contact edge 15b is pushed, the restriction edge 15c moves in the opposite direction to the restriction edge 1 of the engaging body 11.
1a, it moves to the left in the figure, and the lower end edge 15 of the claw 15 moves onto the upper edge 11c of the fan-shaped engaging portion 11b of the engaging body 11.
d invades. Then, by the swinging of the claw 15, the claw portion 15a
engages with the window 17a of the locking piece 17 on the seat side, and the upward movement of the seat 7, that is, the opening movement of the upper surface of the seat support 6, is prevented, and the fuel tank, etc. in this area cannot be opened in a locked state. Can not. The locked state is shown by chain lines C, D, and E.

Even if you remove the key from the main switch 11 in the locked state and try to release the parking brake by lowering the lever 9, the lower end 15d of the pawl 15 and the upper edge 11c of the engaging body 11 will collide due to the advance of the pin 14 of the main switch 11. The collision prevents the support shaft 10 from rotating counterclockwise, and therefore the parking brake cannot be released. To release the key, insert the key into the groove 13 and set it to the off position, then the pin 14 will move back, the pawl 15 will swing counterclockwise, and the engaging body 11 will be released and the lever can be operated. Become.

In the example shown above, a seat lock mechanism is provided, but by removing this and bringing the pin 14 and the engaging body 11 closer together, or by lengthening the pin 14, the pin 14 and the engaging body 11 can perform the above operation. In this embodiment, the parking brake lock and seat lock can be performed in one operation, but they may be performed separately or only the parking brake lock can be performed.

As is clear from the above, according to the present invention, the operation of the parking brake is related to the operation of the main switch, and the key cannot be removed unless the parking brake is activated. Since the lock cannot be unlocked unless the switch is operated to release the lock, it prevents forgetting to release the lock, which is convenient for preventing theft, etc. In addition, it has a simple structure and can be done using the existing main switch, making it easy to use. It has many advantages, such as being able to plan the intended purpose.

In the embodiment, the engaging body 11 and pin 1 provided on the support shaft
4 was used, but it should be noted that the specific means are arbitrary.
