Claims

[Scope of utility model registration request]

(1) A reciprocating element having a serrated cam feed surface formed on the end face is provided at the lower end of the operating iron connected to the movable iron core of the solenoid, and a reciprocating element is provided that allows only the reciprocating motion in the axial direction of the reciprocating element to be guided. A stator having guide teeth having the same inclination as the cam feeding surface is fixed to the inside of the piston rond, and a serrated opposing cam feeding surface is provided opposite to the cam feeding surface of the reciprocating child and the guide teeth of the stator. The rotor is equipped with an adjustment valve for adjusting the opening of the oil passage, and a rotor is provided with a rotor having an opening in the opposite cam feeding surface so as to cause the guide teeth to retract at one time. A damping force adjustment device for a shock absorber, characterized in that:

(2) A damping force adjustment device for a shock absorber according to claim 1 of the utility model registration claim, in which a limit switch (detection switch) is attached to the protruding end of the movable iron core in the piston rond.
