An annular gap between the seat pipe and the cylinder constitutes an oil reservoir chamber filled with gas, and a check valve is provided on the piston to allow hydraulic oil to flow from the curved chamber B into the oil chamber A. In the shock absorber, the shock absorber is equipped with a damping valve that causes hydraulic oil to flow out from the oil reservoir chamber while generating a damping force, and a check valve that causes hydraulic oil to flow from the oil reservoir chamber into the oil chamber B, the check valve provided on the piston. A shock absorber with a lock, characterized in that a shutoff valve that opens and closes according to pilot pressure is provided in series with the piston rod, and a pilot passage for guiding pilot pressure from the outside to the shutoff valve is formed vertically through the piston rod.
