The spring (18) is arranged between the sleeve case (11) and the fork stem (5). The free cushion bushing (20) is mounted to the lower edge of the sleeve case (11) and can be freely installed and removed as well as slide on the outer peripheral surface of the fork stem (5) controls relative movement of the handlebar stem (4) and the fork stem (5) caused by friction on the outer peripheral surface of the fork stem (5).
