Abstract A transmission operating device comprises: a frame a change speed lever supported on the frame by a first ball joint, a first control cable and a second control cable extending in the plane crossing with an axis of the change speed lever and being arranged substantially parallel to each other, a bell crank being provided on the frame so as to rotate around a first axis extending substantially parallel to the change speed lever and having a first arm extending in the direction crossing with the first control cable and a second arm extending substantially parallel to the second control is connected with the change speed lever so as to rotate around a second axis crossing with the axis of the change speed lever, has the other end connected with the second arm by means of a second ball joint, and extends in the direction crossing the second arm. One end of the first control cable is connected with the first arm, and one of the second control cable is connected with the change speed lever. When operating the change speed lever in the direction perpendicular to the control cables, an inner wire of one of the control cables is smoothly pushed or pulled. When the operating in the direction parallel to control cables, an inner wire of the other control is smoothly pushed or pulled. The structure of the device is simplified and parts of the device are sporadically assembled.
A transmission operating device comprising: (a) a frame; (b) a first ball joint provided on a lowered portion of the frame; (c) a change speed lever supported on the frame by means of the first ball joint; (d) a first control cable and a second control cable extending in the plane crossing with an axis of the change speed lever and being arranged substantially parallel to each other; (e) a bell crank being provided on the frame so as to rotate around a first axis extending substatially parallel to the change speed lever and having a first arm extending in the direction crossing with the first control cable and a second arm extending substantially parallel to the second control cable; and (f) a connecting link of which one end is connected with the change speed lever so as to rotate around a second axis crossing with the axis of the change speed lever, and of which the other end is connected with the second arm by means of a second ball joint, and extending in the direction crossing with the second arm, wherein one end of the first control cable is connected with the first arm, and one end of the second control cable is connected with the change speed lever.
