An operation device includes a main body, a lifting and lowering mechanism unit movably supported with respect to the main body and including a driven portion configured to receive driving force for movement of the lifting and lowering mechanism unit, a driving unit attached to the main body and configured to drive the lifting and lowering mechanism unit by a driving pin provided on a rotation gear. The lifting and lowering mechanism unit includes a groove portion into which the driving pin is accommodated by rotation of the rotation gear when the driving unit is mounted on the main body.

Operation device and method for manufacturing the same

An insulator includes a plurality of electrical conductors and a main body. One ends of the plurality of electrical conductors are electrically connected to a ground terminal or a plurality of input terminals of a motor. The main body includes an insulating material. Other ends of the plurality of electrical conductors are disposed adjacent to each other on the main body in a direction intersecting with a direction of an output shaft of the motor.

Motor insulator for reducing radiation noise

A gear drive device includes a first gear, a second gear that meshes with the first gear to allow torque transmission, and a biasing member that applies rotational torque in one direction to the first gear or the second gear. The first gear and the second gear are brought into contact at a contacting tooth surface thereof by the biasing member. At least one of the first gear and the second gear includes a non-contacting tooth surface that is on an opposite side of the contacting tooth surface and partially removed.

Gear drive device

A gear drive device includes a first gear, and a second gear that meshes with the first gear to allow torque transmission. At least one of the first gear and the second gear includes a fan-type gear. The first gear and the second gear each include a guide portion, and the guide portion is configured to position the first gear and the second gear in a gear rotation direction upon installation thereof.
