Damper and valve device

A main valve (valve member) is configured so as to be in contact with only a ridge (second protrusion) on the inner peripheral side of a seat (first seat) in a state in which the main valve is assembled to a piston. Therefore, the radial contact width of the main valve and the seat part can be narro...

Summary:A main valve (valve member) is configured so as to be in contact with only a ridge (second protrusion) on the inner peripheral side of a seat (first seat) in a state in which the main valve is assembled to a piston. Therefore, the radial contact width of the main valve and the seat part can be narrowed, and the contact diameter of the main valve and the seat part can be kept constant by managing the radial dimension of the edge part on the inner peripheral side of the seat part, so that the deviation of the valve opening point and the damping force can be suppressed. 主阀(阀部件)在组装于活塞的状态下，仅与座部(第一座部)的内周侧的棱部(第二凸部)抵接而构成。由此，能够使主阀与座部的径向接触宽度变窄，通过对座部的内周侧的棱部的径向尺寸进行管理而将主阀与座部的接触直径保持为恒定，从而能够抑制阀开阀点以及衰减力的偏差。
