そのときに「カチッ」というクリック音を発生する。Between the two bearing plates 4, a spring receiving base 19 is provided integrally with the bearing plates 4 on both sides at a position corresponding to the cutout portion 17 of the leg 5 (see FIG. 2). The curved click spring 8 is attached to the spring receiving base 19. The heel 17 of the leg 5 abuts and locks on the rear surface of the click spring 8 with the locking member 7 fitted in the valley 6 of the gear-shaped portion 2 (see FIG. 4). The locking member 7
In a state in which the click spring 8 has escaped from the trough 6, the click spring 8 comes into contact with the front side surface of the click spring 8 and is locked (see FIG. 2). The heel 17 of the leg 5 overcomes the click spring 8 by elastically deforming it.
At that time, a clicking sound is generated.

る。The present invention is as described above, and the pedal 10
The wheel 1 can be stopped and released only by the operation of stepping on the foot, so that the operation is much easier compared to the above-described conventional example in which the body must be bent to operate by hand. There is. Incidentally, a method of operating using a lever without providing the pedal 10 as in the present invention is also conceivable,
It is necessary to use both the sole and the instep of the lever to swing the lever, and it is difficult to operate the wheel when stopping and releasing the wheel because the operation of the foot is reversed. There is also a problem that, for example, when wearing a sandal or the like, raising the lever with the instep of the foot causes the lever to directly hit a finger or the like and hurt. On the other hand, in the present invention, even when stopping the wheel, when releasing it,
Since the same operation of depressing the pedal 10 with a shoe sole or the like, such a problem can be solved. Further, the present invention relates to a pedal 1
When the leg 5 is rotated, the click spring 8 is elastically deformed and generates a click sound.
Since the user can reliably detect the state of being inserted into and the state of being removed from the device, there is also an effect that erroneous operation can be prevented. Further, the present invention has the advantage that the structure is simple and the manufacture and assembly are easy as compared with the conventional example.
