PURPOSE: To prevent a cable and a cord, even when loosened, from being interposed by providing a handle stopper between the upper end of a head pipe and the bottom surface of an upper side bracket.

CONSTITUTION: In a motorcycle, upper/lower brackets 4 are connected to the upper/lower of a steering shaft 3 turnably mounted and inserted through a head pipe 2 in the front end of a frame 1, to connect an upper part of right/left fork tubes 5 to both sides of the upper/lower brackets 4, and right/left movable stoppers 8 hit a stopper 7 so as to determine a steering angle of a handle 6 by protrusively providing the stopper 7 in an upper end front side of the head pipe 2 and the movable stoppers 8 right/left in the bottom surface of the upper side bracket 4.
