发明名称 Shock absorber
摘要 Provided is a shock absorber that includes a disk support section protruding between an intermediate seat and an inner seat, having a tip height position in a protruding direction higher than that of the inner seat and lower than that of the intermediate seat, and continuously or discontinuously disposed in an annular shape. In a state in which a first disk is pressed against the inner seat and placed on an outer seat, the intermediate seat and the disk support section, in the first disk, a first bending section bent in a convex shape toward a valve main body side is formed between the inner seat and the disk support section, and a second bending section bent in a convex shape toward a side spaced apart from the valve main body is formed between the disk support section and the outer seat.

主权项 1. A shock absorber comprising: a cylinder in which a working fluid is sealed; a piston slidably inserted into the cylinder and configured to partition the inside of the cylinder into two chambers; a piston rod connected to the piston and extending to the outside of the cylinder; a plurality of paths through which the working fluid flows due to sliding movement of the piston; and a damping force generating mechanism installed at a portion of the path and configured to suppress a flow of the working fluid to generate a damping force, wherein the damping force generating mechanism comprises: a valve main body through which the path passes; an annular outer seat protruding to the valve main body; an inner seat protruding into the outer seat of the valve main body; an annular intermediate seat protruding to surround an opening section of the path between the outer seat and the inner seat of the valve main body; a disk support section protruding between the intermediate seat and the inner seat, having a tip height position in a protruding direction higher than that of the inner seat and lower than that of the intermediate seat, and continuously or discontinuously disposed in an annular shape; and a first disk placed to be capable of sitting on the outer seat, the inner seat, the intermediate seat and the disk support section, and wherein, in a state in which the first disk is pressed against the inner seat and placed on the outer seat, the intermediate seat and the disk support section, in the first disk, a first bending section bent in a convex shape toward the valve main body side is formed between the inner seat and the disk support section, a second bending section bent in a convex shape toward a side spaced apart from the valve main body is formed between the disk support section and the outer seat, and the shock absorber sits on the intermediate seat and the outer seat.
