Abstract
A motor device includes a base portion; a transmission portion that is formed with the base portion as one member and is wound around at least a part of an outer periphery of a rotator; and a driving portion which is supported by the base portion, moves the transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the transmission portion, and returns the transmission portion to a predetermined position in a state in which the rotation force transmission state is released.
Claims30
A motor device comprising:
- a base portion;
- a transmission portion that is formed with the base portion as one member and is wound around at least a part of an outer periphery of a rotator, the transmission portion and the base portion being formed in one plate shape member;
- and
- a driving portion which is supported by the base portion, moves the transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the transmission portion, and returns the transmission portion to a predetermined position in a state in which the rotation force transmission state is released.

A motor device comprising:
- a transmission portion that is wound around at least a part of an outer periphery of a rotator;
- a driving portion which moves the transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the transmission portion, and returns the transmission portion to a predetermined position in a state in which the rotation force transmission state is released;
- an elastic portion that causes an elastic force to act on the transmission portion in a direction that is separated from the rotator;
- and
- a base portion that surrounds an outer periphery of the transmission portion,
- wherein the elastic portion is disposed between the transmission portion and the base portion.
3 more elements
A motor device comprising:
- a base portion;
- a transmission portion that is formed with the base portion in one member and is wound around at least a part of a rotator, the transmission portion and the base portion being formed in one plate shape member;
- a driving portion that, while a rotational force is transmitted between the rotator and the transmission portion, moves the transmission portion by a certain distance, and that, while the rotation force transmission state is released, returns the transmission portion to a predetermined position;
- and
- a portion that is formed with the base portion in one member and supports the transmission portion.
2 more elements
A motor device comprising:
- a base portion;
- a transmission portion that is formed with the base portion as one member and is wound around at least a part of an outer periphery of a rotator, the transmission portion having at least one cut portion;
- and
- a driving portion which is supported by the base portion, moves the transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the transmission portion, and returns the transmission portion to a predetermined position in a state in which the rotation force transmission state is released.
1 more element
A motor device comprising:
- a first base portion;
- a first transmission portion that is formed with the first base portion as one member and is wound around at least a part of an outer periphery of a rotator;
- a first driving portion which is supported by the first base portion, moves the first transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the first transmission portion, and returns the first transmission portion to a predetermined position in a state in which the rotation force transmission state is released;
- a second base portion;
- a second transmission portion that is formed with the second base portion as one member and is wound around at least a part of an outer periphery of the rotator;
- and
- a second driving portion which is supported by the second base portion, moves the second transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the second transmission portion, and returns the second transmission portion to a predetermined position in a state in which the rotation force transmission state is released.
