Abstract: A shock absorber varying damping force is provided to increase damping force by contracting mounting spaces of a moving unit narrow in an operation case when an operation unit bumps up and down. A shock absorber varying damping force comprises an operation case(200), an operation rod(300), and a moving unit(400). The operation case has an operation space whose upper and lower parts are inclined parts. The operation rod passes through the top of the operation case and reciprocates vertically in the operation space. The moving unit is located in the operation space of the operation case and attached to the end of the operation rod. The moving unit moves along the operation case vertically when the operation rod bumps up and down. The moving unit includes a fixed bodies(440a,440b), movable bodies(420a,420b), and springs(460). The movable bodies expand or contract inside the operation case, as moving along the operation space vertically.

Abstract: PURPOSE: A steering device is provided to improve the productivity by reducing shimmy vibration in a steering shaft. CONSTITUTION: A transferring unit of steering force connects or releases an upper steering shaft(10) and a lower steering shaft(12) selectively. A reducing unit of shimmy vibration isolates the shimmy vibration by installing between the upper steering shaft and the lower steering shaft. A realizing unit of operating force gives operating force to the transferring unit of the steering force. A detecting unit of the shimmy vibration detects the shimmy vibration to be transferred to the steering shafts. A control unit controls the realizing unit of the operating force when the shimmy vibration is detected. Thereby, the steering efficiency is improved and the shock through the steering shafts is relaxed.
