Abstract: One embodiment provides a damping force generator. The damping force generator includes: a valve body having a compression-side inlet port into which the oil pushed by the piston flows; and a compression-side damping valve provided so as to block a port outlet and elastically deformed according to pressure of the oil flowing into the compression-side inlet port to thereby exhibit damping force. An opening cross-sectional area of a port inlet opening is larger than a passage cross-sectional area of the compression-side inlet port.

Abstract: One embodiment provides a shock absorber. The shock absorber includes a reservoir communication path through which a damping force generator and a reservoir communicate with each other, a compression-side communication path through which a piston-side oil chamber and the damping force generator communicate with each other, and a compression-side inlet port which is provided in the damping force generator and into which oil flows from the compression-side communication path and which has a compression-side valve that generates damping force. The cross-sectional area of the reservoir communication path is smaller than the cross-sectional area of the compression-side inlet port.
