However, in the present invention, the clutch pedal 3 is
This cable-operated clutch operating mechanism operates the clutch via the operating cable 6 by stepping on C and operates the clutch via the operating cable 6. A bracket 9 is attached to support an outer receiver 10 having a threaded portion 10a on the outer periphery and an adjustment body 10b screwed to the threaded portion 10a, and the supporting bracket 9
A contact portion 9a to the clutch pedal 3 is formed,
The support bracket 9 is attached to the depression limit position of the clutch pedal.

The support bracket 9 is a horizontal member 9b as shown in FIG.
Downward members 9C and 9d are provided from the front and rear edges of the horizontal member 9b, respectively, to maintain a constant distance between both downward members 9C and 9d, and a guide tube 9e is provided on the upper surface of the horizontal member 9b. It is shaped like a guide hole 9f passing through the guide tube 9e, and the guide 7L9f is formed to have a slightly larger diameter than the threaded portion 10a of the outer receiver 10.

The support bracket 9 also uses the outer surface of the downward member 9d as a contact portion 9a for the clutch pedal 3, and the depression limit position of the front end surface of the arm portion 3b of the clutch pedal 3 as shown by the imaginary line in FIG. It is attached to the stationary member 2 so that the contact portion 9a is located at the same position.

The adjustment body 10b of the outer receiver 10 has an upper half formed into a cylinder with a small diameter, a lower half formed into a substantially regular octagonal nut shape with eight side surfaces, and four parallel to each other. The distance between the side surfaces of each set is set to a fitting dimension corresponding to the facing distance between the inner surfaces of both downwardly directed members 9C and 9d in the support bracket 9, respectively.

Reference numeral 11 denotes a structure for setting the return limit position when the clutch pedal 3 returns, and an abutment member 11a is provided at the end of the arm 3b of the clutch pedal 3 in the return operation direction. A support plate 11b is attached to a stationary member 2 spaced a certain distance from the member 11a in the return movement direction, and a bolt 11c is screwed onto the support plate 11b so as to protrude in the direction of the abutting member 11a, nut 1
1d and 11d from the support plate 1l b to the contact member 11
The protrusion length in the a direction can be adjusted.
The clutch pedal 3 is connected to the contact member 11a by the bolt 11C.
It is made to stop when it comes into contact with the object.

In the above structure, the end of the operating cable 6 on the clutch side (opposite to the clutch side) can be attached by first rotating the adjusting body 10b, and then vertically moving the adjusting body 10b along the threaded portion 9a. to a certain position.

Next, in the deflected state, among the four sets of parallel side surfaces of the adjustment body 10b, the side surfaces of the set parallel to the downward members 9b, 9C are fitted between the downward members 9b, 9C. , the threaded portion 10a of the outer receiver 10 is guided upward from the guide hole 9e of the support bracket 9, the upper end of the adjusting body 10b is brought into contact with the lower surface of the horizontal member 9b, and the end of the inner cable 8 is connected to the clutch pedal 3. This is done by engaging the tip of the arm portion 3a.

When adjusting the vertical mounting position of the outer receiver 10 to the support bracket 9, adjust the adjustment body 10b of the outer receiver 10 by lowering it from the support bracket 9 and rotating it by an angle corresponding to the adjustment distance. Then, the support bracket 9 is forced to fit between the downward members 9C and 9d again.
