Claims

[Scope of utility model registration request]

A communication passage is formed in the piston rod of the shock absorber to communicate the piston upper chamber and the piston lower chamber that bypass the piston, and a leaf valve is provided at the lower end of the communication passage, and the operating range of the leaf valve is limited to a low piston speed range. An absorber valve characterized by being set in a region where damping force is generated.
