いる。As shown in Figure 1, a known measure to eliminate the above discomfort is to drill an inner wire penetration hole 2 in the center of the inner wire 8 on the accelerator pedal side (operation side) near the terminal fitting 7 of the control cable for accelerator operation. In addition, a shock absorber 1 is provided, which is a short, small cylindrical rubber body having a window hole 3 passing through the inner wire penetration hole orthogonally to the inner wire penetration hole axis, and having a hemispherical convex portion integrally connected to the left side in the figure, that is, on the accelerator pedal side. and further fitting a bushing 5 adjacent to the buffer body 1, which has a spherical recess that fits into the hemispherical convex portion of the buffer body 1 and has a protruding leg 6 at the other end,
A structure is widely used in which the terminal fitting 7, the buffer body 1, and the bushing 5 are brought into contact with each other in the direction of the arrow shown in the drawing so that the terminal fitting 7, the shock absorber 1, and the bushing 5 are integrally connected, and the accelerator pedal end (not shown) is engaged and connected to the protruding leg 6.
