機構。[Claims for Utility Model Registration] A damping force generating valve that causes hydraulic oil in a chamber that contracts in accordance with the compression stroke of a piston to flow out into an oil reservoir chamber;
A damping force adjustment mechanism for a shock absorber, comprising a detection spring that is deflected by the spring force when the suspension spring is compressed, and a control rod that moves according to the amount of deflection of the detection spring and increases the throttling resistance of the damping force generating valve. .

Claims

[Scope of utility model registration request]

A damping force generation valve that causes the hydraulic oil in the chamber whose pressure increases in accordance with the stroke of the piston to flow out into the oil reservoir chamber, a detection spring that deflects due to the spring force when the suspension spring is compressed, and a damping force generating valve that causes the hydraulic oil in the chamber to flow out into the oil reservoir chamber, whose pressure increases according to the stroke of the piston, and a detection spring that deflects due to the spring force when the suspension spring is compressed. and a control rod that moves to increase the set pressure of the damping force generating valve.
