Abstract
In a front fork in a two-wheeled vehicle or motor vehicle, a partition wall member sectioning an oil reservoir chamber into upper end lower sides is provided in an upper portion of a hollow pipe. A center hole and an expansion and compression common flow passage are formed in the partition wall member. The expansion and compression common flow passage is provided with a deflection valve in a state of being supported in an inner periphery, and a check valve in a state of being supported in an outer periphery, in such a manner that an outer periphery of the deflection valve and an inner periphery of the check valve are at least partially overlapped. A first spring supporting the deflection valve in a back surface and a second spring supporting the check valve in a back surface are provided. A small gap is provided in the overlapping portion between the deflection valve and the check valve.
