Provided is a valve mechanism which includes an orifice collar 80 having a hollow portion 82 penetrating in an axial direction, a plurality of valve bodies 70 including a spoke valve 71C arranged to be in contact with an axial end surface of the orifice collar 80, and a drive valve 61 arranged movably in the axial direction and disposed on a side opposite to the orifice collar 80 with respect to the plurality of valve bodies 70, where the drive valve 61 includes a shaft portion 61j and a step portion 61b extending from the shaft portion 61j to a radial outside and the shaft portion 61j has a tip portion 61e which extends further on the orifice collar 80 side than the step portion 61b and of which an outer diameter is smaller than an outer diameter of the step portion 61b, and further a gap between the plurality of valve bodies 70 is changed by elastically deforming an inner peripheral portion of the valve body 70 which comes into contact with the drive valve 61 which is moved in a direction approaching the valve body 70 in a direction approaching the orifice collar 80 with respect to an outer peripheral portion of the valve body 70.
