And a pedal arm 53 extending upwardly having a lower end 2. The upper end of the pedal arm 53 is tightened with a bolt 54 and a nut 55 via a bush 56, a spacer 57, and a return spring 58. It is rotatably supported by a pedal bracket 59 having a substantially U-shaped cross section with its portion arranged downward. The upper part and the front part of the pedal bracket 59 are attached to the inside of the vehicle compartment 61 of a dash panel 62 that separates the engine compartment 60 and the vehicle compartment 61. For this reason, the pedal bracket 59
Bolt holes 62 and 63 are formed in the upper part and the front part, respectively. The dash panel 62 is provided with a support bracket 65 having a welding nut 64, and a pair of right and left fastening bolts 66 are protrudingly provided. I have. In such a pedal bracket 59, the upper mounting portion 59 a is configured such that the tightening bolt 67 is inserted from below into the welding nut 64 through the bolt hole 62.
The front mounting portion 59b is fixed by screwing a nut 68 to a tightening bolt 66 through the left and right bolt holes 63 toward the front, and is mounted on the dash panel 62. The arrow X in FIG. 5 indicates the load direction.

The pedal bracket 59 is provided with a stay 70 to which a bracket-side fully-closed stopper 69 is fixed and a fully-opened stopper bracket 71. The stay 70 and the fully-opened stopper bracket 71 have both right and left end walls. It is mounted on and suspended. On the other hand, a pedal-side stopper stay 73 to which a cushion 72 is fixed is attached to the pedal arm 53 of the clutch pedal 51. Therefore, when the driver operates the clutch pedal 51
When the pedal step portion 52 is depressed forward (in the direction of arrow Y in FIG. 5), the upper end of the pedal arm portion 53 comes into contact with the fully-open stopper bracket 71, and the clutch pedal 51
Will be restricted from moving forward. When the driver releases the pedal depression portion 52 of the clutch pedal 51, the resilient force of the return spring 58 causes the pedal arm portion 53 to release.
Returns to the rear, and the pedal-side stopper stay 73 fixed thereto abuts the bracket-side fully-closed stopper 69 of the pedal bracket 59, thereby restricting the rearward movement of the clutch pedal 51.

Further, a clutch cable 74 composed of a double cable is provided at a lower portion on the front side of the pedal bracket 59.
