PROBLEM TO BE SOLVED: To suppress the movement of a pedal device by making the displacement of a lever portion to a rotation fulcrum side small in an operation forward stroke.SOLUTION: A lever portion 30 is supported by a support post portion 12 in a freely rotational manner centering around a rotation fulcrum J and a tip portion 32 of an extension portion 32 is depressed and operated by a sole 22a. The extension unit 32 is always biased upward by a spring 14 and the extension unit 32 comes into contact with a stopper portion 13a, and thereby the initial position of rotational movement of the extension portion 32 is regulated in a non-operation state. The height HA of the rotation fulcrum J in the case where a base portion 11 is installed on a floor 20 is higher than the height HB of a force point (contact point P) where the sole 22a in the non-operation state engages with the tip portion 32b.SELECTED DRAWING: Figure 1 |
