Claims

[Scope of utility model registration request]

A variable damping force type shock absorber including a cylinder and a piston that is reciprocably inserted into the cylinder and cooperates with the cylinder to define two cylinder chambers of variable volume; A piston body having a first passage means for communicating and connecting the two cylinder chambers, a piston rod integrally supporting the piston body and having a second passage means for communicating and connecting the two cylinder chambers, and an axis line within the piston rod. a spool that is arranged to be reciprocally movable along the axis and controls an effective passage cross-sectional area of the second passage means according to a position along the axis, and an electromagnetic actuator that drives and positions the spool along the axis; selectively positioned in a first position to engage the spool and prevent movement of the spool along the axis; and a second position to disengage from the spool and allow movement of the spool along the axis. A variable damping force shock absorber with a stopper.
