Abstract
A motor may include a motor main body and an urging member. The urging member is provided with an end plate part having a plate spring part for urging the rotor and an engaging plate part which is extended along an outer peripheral face of a tube-like body part structuring an outer peripheral face of the motor main body. The engaging plate part is provided with a side plate part extended from the end plate part along the outer peripheral face of tube-like body part, a hook part which is bent from a tip end part of the side plate part to an inner side and is engaged with an opening part which is formed in the tube-like body part, and a pawl part which is bent from a tip end part of the hook part and is engaged with an inner peripheral face of the tube-like body part.
Claims13
A motor comprising:
- a motor main body comprising a rotor having a rotation shaft and a stator disposed on an outer peripheral side of the rotor;
- and
- an urging member configured to urge the rotor to one side in a motor axial line direction;
- wherein a tube-like body part structuring an outer peripheral face of the motor main body is formed with an opening part which is opened toward an outer side in a radial direction;
- wherein the urging member comprises:
- an end plate part which is provided with a plate spring part configured to urge the rotor and is located on the other side with respect to the tube-like body part in the motor axial line direction;
- and
- an engaging plate part which is extended toward the one side in the motor axial line direction from the end plate part along an outer peripheral face of the tube-like body part;
- and
- wherein the engaging plate part comprises:
- a side plate part which is extended from the end plate part toward the one side in the motor axial line direction along the outer peripheral face of tube-like body part;
- a hook part which is bent from a tip end part of the side plate part to an inner side in a radial direction and is engaged with a wall face of the opening part located on the other side in the motor axial line direction;
- and
- a pawl part which is bent from a tip end part of the hook part toward the other side in the motor axial line direction on an inner side of the tube-like body part.
