The arm portion 2 is composed of two left and right arms 9,
10 are overlapped with each other except for a part of the lower end, and the overlapping portions are joined by welding,
The combined plate thickness t ₂ of the arms 9 and 10 is thinner than the plate thickness t ₁ of the conventional arm portion (therefore, the plate thickness of each of the arms 9 and 10 is, for example, 2.0 mm). . A hook 12 for hooking and connecting the clutch cable 11 is provided on the upper end of the arm 2, and a tubular boss 3 is provided below the hook 12. A bolt shaft 13 that rotatably supports the clutch pedal 1 is inserted into the boss portion 3, and the bolt shaft 13 serves as a rotation center of the clutch pedal 1.

Further, as shown in FIGS. 1 and 2, beads 14 and 15 are provided corresponding to the middle part of the arm portion 2 by bending a part of the arms 9 and 10 outwardly. The beads 14 and 15 are formed in a substantially arcuate shape in a state of being combined with each other, whereby the sectional modulus of the arm portion 2 is improved and the strength of the clutch pedal 1 is increased. Moreover, a return stopper portion 6 projecting rearward of the vehicle body is joined to the rear side of the intermediate portion of the arm portion 2 by welding, and the return stopper portion 6 is provided on the pedal bracket 8 side.
