A valve mechanism includes: a cylindrical body; a plurality of valve bodies; and a drive valve. The drive valve includes a shaft portion having therein a flow path penetrating in the axial direction, and a step portion extending from an outer peripheral surface of the shaft portion to a radial outside of the shaft portion. The shaft portion has a tip portion which extends further on the cylindrical body side than the step portion. An outer diameter of the tip portion is smaller than an outer diameter of the step portion. A gap between the valve bodies is changed by elastically deforming an inner peripheral portion of the valve body, which comes into contact with the drive valve moved in a direction approaching the valve body, in a direction approaching the cylindrical body with respect to an outer peripheral portion of the valve body.
