To obtain, as one example, a rotation/linear motion conversion device which can suppress the tight fastening of a rotating member and a linear motion member.SOLUTION: This rotation/linear motion conversion device comprises, as one example: a rotating member which is rotationally driven around a rotation center by a motor; a linear motion member which linearly progresses to a direction along the rotation center according to the rotation of the rotating member; and a friction part having a first face which is formed at either of the rotating member and the linear motion member, and oriented to either of a direction approximating the rotation center and a direction separating from the rotation center. A second face which is oriented to the other of the direction approximating the rotation center and the direction separating from the rotation center is formed at the other of the rotating member and the linear motion member, and a friction force is generated by the linear progress of the linear motion member in a state that the first face pressure-contacts with the second face.SELECTED DRAWING: Figure 1
【課題】一例として、回転部材と直動部材とが固く締まり合うことを抑制できる回転直動変換装置を得る。【解決手段】実施形態に係る回転直動変換装置は、一例として、モータによって回転中心まわりに回転駆動される回転部材と、前記回転部材の回転に応じて前記回転中心に沿う方向に直進する直動部材と、前記回転部材と前記直動部材とのうち一方に設けられ、前記回転中心に近づく方向及び前記回転中心から遠ざかる方向のうち一方に向く第1の面を有する摩擦部と、を備え、前記回転部材と前記直動部材とのうち他方に、前記回転中心に近づく方向及び前記回転中心から遠ざかる方向のうち他方に向く第2の面が設けられ、前記第1の面が前記第2の面に圧接する状態で前記直動部材が直進することで、前記第1の面と前記第2の面との間で摩擦力が生じる。【選択図】図1
