A compression rod inserted in a hollow gearshift lever is pushed upward by a coil spring. The compression rod is moved downward against the coil spring when an operation button of an operation knob formed on an upper portion of the gearshift lever is operated. A stopper is attached on a lower end opening of the gearshift lever, and the stopper prevents the coil spring from falling out. In the stopper, a leg portion and a protrusion portion are inserted in the gearshift lever, and a tab portion is locked in a lock hole of the gearshift lever.
