Drive transmitter, driver, and image forming apparatus
A drive transmitter is provided that includes an electromagnetic clutch, an energization part integrated with the electromagnetic clutch and to be electrically connected to a connection part of a device body, a field core integrated with the energization part, a rotor boss part, and a tilt restrictor in engagement with the energization part. The tilt restrictor restricts tilting of the field core to the rotor boss part when an external force is applied to the energization part from the connection part in electrical connection with the energization part.
1 . A drive transmitter comprising:
an electromagnetic clutch;
an energization part integrated with the electromagnetic clutch and configured to be electrically connected to a connection part of a device body;
a field core integrated with the energization part;
a rotor boss part; and
a tilt restrictor in engagement with the energization part, the tilt restrictor configured to restrict tilting of the field core to the rotor boss part when an external force is applied to the energization part from the connection part in electrical connection with the energization part.
2 . The drive transmitter according to claim 1 ,
wherein the tilt restrictor includes:
an opposed part facing the energization part from a side in a direction orthogonal to the external force; and
a biasing member configured to bias, toward the opposed part, the energization part from another side in the direction.
3 . The drive transmitter according to claim 2 ,
wherein the tilt restrictor further includes another opposed part facing the energization part from the another side in the direction, and
the biasing member is between the opposed part and the another opposed part, the biasing member being a damping material having a thickness larger than a clearance between the opposed part and the another opposed part between which the energization part is interposed.
4 . The drive transmitter according to claim 2 ,
wherein the biasing member includes a resin material having flexibility or elasticity.
5 . The drive transmitter according to claim 4 ,
wherein the resin material is in a plate shape and has a face inclined in the direction, the face configured to bias the energization part toward the opposed part.
6 . The drive transmitter according to claim 1 ,
wherein the tilt restrictor further includes a contact part configured to have contact with the energization part against the external force in a direction orthogonal to the external force.
7 . The drive transmitter according to claim 1 ,
wherein the tilt restrictor includes:
an opposed part facing the energization part from a side in a direction orthogonal to the external force; and
another opposed part facing the energization part from another side in the direction,
wherein the energization part is press-fitted between the opposed part and the another opposed part.
8 . The drive transmitter according to claim 1 ,
wherein the tilt restrictor is configured to restrict the tilting of the field core due to a clearance between the field core and the rotor boss part.
9 . A driver comprising:
the drive transmitter according to claim 1 ; and
a drive source.
10 . An image forming apparatus comprising the driver according to claim 9 .
