Cover fixing structure and motor

A motor comprising:

• a cover fixing structure for fixing a cover to a support member;
• wherein the support member comprises a first support unit configured to support the cover on one side in a first direction, and a second support unit configured to support the cover at one side in a second direction orthogonal to the first direction;
• wherein one of the cover and the support member comprises a biasing force generation unit configured to generate, in a case that the cover is pressed against the first support unit, a biasing force for biasing the cover in an inclined direction inclined toward both an other side in the first direction and the one side in the second direction;
• and
• the second support unit comprises a first abutment unit configured to abut the cover from the one side in the second direction, and a second abutment unit configured to abut the cover from the other side in the first direction;
• a motor main body comprising a motor axis extending along the second direction;
• a frame comprising a first plate fixed to an end on an other side in the second direction of the motor main body, a second plate facing the first plate on the other side in the second direction, and a third plate configured to couple the first plate and the second plate at one side in the first direction;
• a rotation shaft arranged between the first plate and the second plate;
• a gear transmission mechanism configured to transmit rotation of a motor shaft of the motor main body to a gear unit of the rotation shaft;
• and
• a gear cover fixed to the frame to cover the gear transmission mechanism between the first plate and the second plate,
• wherein
• the frame is the support member,
• the gear cover is the cover,
• the third plate is the first support unit, and
• the first plate is the second support unit.
