发明名称 FRONT FORK
摘要 A front fork has a damping variable leg including: an outer tube at an upper end side; an inner tube at a lower end side and inserted into the outer tube; a piston rod attached to the outer tube and extending toward the lower end side; a piston at a lower end of the piston rod; and a damping force variable device at the piston so as to generate variable damping force by controlling a flow of an operating fluid. The damping variable leg further includes: a conductor member attached to the piston; and a coil conductor covered with an insulating member and attached to the inner tube. The conductor member is configured to be inserted into the coil conductor. The damping variable leg detects a stroke amount of the damping variable leg based on a change in inductance of the coil conductor.

主权项 1. A front fork having a damping variable leg, the damping variable leg comprising: an outer tube provided at an upper end side of the front fork; an inner tube provided at a lower end side of the front fork and inserted into an inner circumference side of the outer tube; a piston rod, an upper end of which is attached to an upper end of the outer tube, the piston rod extending toward the lower end side along an axial direction of the outer tube; a piston provided at a lower end of the piston rod; and a damping force variable device provided at the piston so as to generate variable damping force by controlling a flow of an operating fluid enclosed in the damping variable leg, wherein the damping variable leg further comprises: a conductor member, an upper end of which is attached to the piston, the conductor member extending toward the lower end side along the axial direction; and a coil conductor covered with an insulating member, a lower end of the coil conductor being attached to a lower end of the inner tube, the coil conductor extending toward the upper end side along the axial direction, the coil conductor being configured such that the conductor member can be inserted into the coil conductor, and the damping variable leg detects a stroke amount of the damping variable leg based on a change in inductance of the coil conductor.
