Abstract
Claims
1. In a linear motion conversion device that converts the rotational motion of a rotating part into the linear motion of a linear motion part, and uses the linear motion part to cause a piston to move linearly inside a cylinder part, A restricted portion that displaces together with the linear motion portion and the piston, a guide member that restricts the rotational motion of the linear motion portion or the piston, and allows the linear motion of the restricted portion, the linear motion portion or the piston, The system includes a clamping portion that clamps the guide member between itself and the cylinder portion in the direction of linear motion of the linear motion portion, thereby restricting the movement of the guide member in the direction of linear motion of the linear motion portion. The clamping portion is, The bearing comprises an outer ring fixed to the cylinder portion and an inner ring through which the rotating portion is inserted, A linear motion converter comprising at least one of the linear motion unit or a buffer unit that buffers the impact caused by the linear motion of the restricted unit.
2. The guide member extends in the direction of linear motion of the linear motion section, with one end supported by the cylinder section and the other end supported by the clamping section. The linear motion converter according to claim 1, wherein the length between the one end and the other end of the guide member is shorter than the distance between the cylinder portion supporting the one end and the clamping portion supporting the other end.
