Abstract
A rotating mechanism which includes a rail of a helical shape formed to be of uniform diameter, a column member disposed at an inner side of the rail, a rotating shaft inserted through and fixed at a center of the column member, a moving body attachable to the rail, and a magnet body disposed slightly separated from the column member.
Claims30
A rotating mechanism comprising:
- a first rail portion that is formed in a helical shape and is rotatable around an axial center;
- a moving portion that is attachable to the first rail portion and is movable along the first rail portion;
- a rail rotating force imparting means for imparting, to a first region of the moving portion, a first force that rotates the first rail portion in a first direction;
- and
- a moving force imparting means for imparting, to a second region of the moving portion, a second force that moves the moving portion from one side of the first rail portion towards another side of the first rail portion,
- wherein a movement of the moving portion relative to the first rail portion and a rotation of the first rail portion in the first direction are repeated by the first force and the second force to move the moving portion to the other side of the first rail portion.

A rotating mechanism comprising:
- a first rail portion that is substantially annular and is rotatable around an axial center;
- a moving portion that is attachable to the first rail portion and is movable along the first rail portion;
- a rail rotating force imparting means for imparting, to a first region of the moving portion, a first force that rotates the first rail portion to a first direction;
- and
- a moving force imparting means for imparting, to a second region of the moving portion, a second force that moves the moving portion in a direction opposite to one side along the first rail portion,
- wherein the first rail portion is restricted in rotation in a second direction that is a direction opposite to the first direction and/or the moving portion is restricted in movement toward the one side along the first rail portion, and
- wherein a movement of the moving portion relative to the first rail portion and a motion of rotating the first rail portion in the first direction are repeatable by the first force and the second force.
