Abstract
A moving body reciprocation mechanism has a rotation shaft and a moving body that engages with a spiral ridge part of the rotation shaft and reciprocates along an axial direction. The state of the moving body changes among: a first state in which the moving body moves in a first movement direction; a second state in which the moving body releases the engagement; and a third state in which the moving body reengages with the spiral ridge part and moves in a second movement direction. The rotation shaft has a planar part and a cylindrical protrusion part. A cylinder part of the moving body has: a first end part that fits onto the cylindrical protrusion part in the second state; and a second end part that radially faces an outer circumferential surface of the spiral ridge part in the second state.
