ABSTRACT:
The combination of a cylindrical casing, a rod member axially reciprocable in the casing, a rotary member fitted in the casing and rotatable therein in relation with axial displacement of the rod member, an inertia member rotatably fitted in the casing opposingly to the rotary member, and a rotation control member interposed between the rotary and inertia members and adapted to rotate the inertia member with the rotary member in rotation at a low speed and to move the inertia member axially away from the rotary member in rotation at a high speed to abut the inertia member against a wall portion of the casing to restrict the rotation of the rotary member. An intermediate brake is provided between the rotary and inertia members to apply a force resistive to relative rotational displacement of the rotary and inertia members.
