Abstract
A shaft-receiving device connects a rotating member and a frame. The rotating member has a rotational axis extending in a first direction and at least one end in the first direction. The frame extends in a second direction perpendicular to the first direction and is formed with a through-hole having an inner peripheral surface. The shaft-receiving device includes a shaft-receiving portion and a pressing member. The one end is inserted into the shaft-receiving portion in the first direction. The shaft-receiving portion is inserted into the through-hole in the first direction and opposes the inner peripheral surface in the second direction. The pressing member opposes the inner peripheral surface in the second direction to press the rotating member toward the inner peripheral surface.

A shaft-receiving device for connecting a rotating member and a frame, the rotating member having a rotational axis extending in a first direction and at least one end in the first direction, the frame extending in a second direction perpendicular to the first direction and being formed with a through-hole having an inner peripheral surface, the shaft-receiving device comprising:
- a shaft-receiving portion into which the one end is inserted in the first direction, the shaft-receiving portion being inserted into the through-hole in the first direction and opposing the inner peripheral surface in the second direction;
- and
- a pressing member opposing the inner peripheral surface in the second direction to press the rotating member toward the inner peripheral surface.
A drum unit comprising:
- a photosensitive drum having a rotational axis extending in a first direction and at least one end in the first direction;
- a frame extending in a second direction perpendicular to the first direction and being formed with a through-hole having an inner peripheral surface;
- a shaft-receiving device comprising:
- a shaft-receiving portion into which the one end is inserted in the first direction, the shaft-receiving portion being inserted into the through-hole in the first direction and opposing the inner peripheral surface in the second direction;
- and
- a pressing member opposing the inner peripheral surface in the second direction to press the photosensitive drum toward the inner peripheral surface.
An image-forming device comprising:
- a photosensitive drum having a rotational axis extending in a first direction and at least one end in the first direction;
- a frame extending in a second direction perpendicular to the first direction and being formed with a through-hole having an inner peripheral surface;
- and
- a shaft-receiving device comprising:
- a shaft-receiving portion into which the one end is inserted in the first direction, the shaft-receiving portion being inserted into the through-hole in the first direction and opposing the inner peripheral surface in the second direction;
- and
- a pressing member opposing the inner peripheral surface in the second direction to press the photosensitive drum toward the inner peripheral surface.
