A damping force generator comprising: a valve body having a port into which oil flows when a piston slides inside a cylinder of a shock absorber ; and a damping valve which is provided so as to block an end of the port and is elastically deformed according to pressure of the oil flowing into the port to thereby open and close the port , wherein an opening cross-sectional area (A1) of an inlet opening of the port through which the oil flows into the port is larger than a passage cross-sectional area (A0) of the port on a side on which the damping valve is disposed, wherein the damping force generating unit is configured such that the damping valve is provided on one end side of the valve body so as to block an outlet opening of the port ; a check valve is provided on the other end side of the valve body so as to block the port ; and the inlet opening of the port is formed to be open between the check valve and a recess which is formed in an outer circumferential surface of the valve body so as to be depressed from the other end side toward the one end side and communicates with the port , characterized in that the valve body integrally includes inner circumferential walls , outer circumferential walls formed on the outer side in the radial direction of the inner circumferential wall , and a plurality of connection walls formed at intervals in the circumferential direction so as to extend in the radial direction to connect the inner circumferential walls and the outer circumferential walls . a valve body having a port into which oil flows when a piston slides inside a cylinder of a shock absorber ; and a damping valve which is provided so as to block an end of the port and is elastically deformed according to pressure of the oil flowing into the port to thereby open and close the port , wherein an opening cross-sectional area (A1) of an inlet opening of the port through which the oil flows into the port is larger than a passage cross-sectional area (A0) of the port on a side on which the damping valve is disposed, wherein the damping force generating unit is configured such that the damping valve is provided on one end side of the valve body so as to block an outlet opening of the port ; a check valve is provided on the other end side of the valve body so as to block the port ; and the inlet opening of the port is formed to be open between the check valve and a recess which is formed in an outer circumferential surface of the valve body so as to be depressed from the other end side toward the one end side and communicates with the port , the damping valve is provided on one end side of the valve body so as to block an outlet opening of the port ; a check valve is provided on the other end side of the valve body so as to block the port ; and the inlet opening of the port is formed to be open between the check valve and a recess which is formed in an outer circumferential surface of the valve body so as to be depressed from the other end side toward the one end side and communicates with the port , characterized in that the valve body integrally includes inner circumferential walls , outer circumferential walls formed on the outer side in the radial direction of the inner circumferential wall , and a plurality of connection walls formed at intervals in the circumferential direction so as to extend in the radial direction to connect the inner circumferential walls and the outer circumferential walls . <EOS>
