Claims

[Scope of utility model registration request]

A push rod 3 is disposed in a case 1 so as to be retractable, and within the case 1 there are brush stands 4, 24 fixed to one end of the push rod 3 and provided with brushes 5, 25, and brush stands 4, 24 of the brush stands 4, 24. The brushes 5 and 25 are in sliding contact with each other, and resistors 11 and 31 are arranged to face the protruding and retracting direction of the push rod 3, and biasing members 7 and 27 are arranged to bias the brush stands 4 and 24 in the protruding direction of the push rod 3. established,
Furthermore, the stroke sensor is characterized in that lead wires 15 extending to the outside are provided at both ends of the resistors 11 and 31 and at the brushes 5 and 25, respectively.
