A process cartridge includes a photosensitive drum and a coupling member operatively connected to the photosensitive drum, with the coupling member including an arm portion and a projection projecting from the arm portion. The arm portion of the coupling member extends from a point that is upstream in the rotational direction of the photosensitive drum towards a point that is downstream in the rotation direction of the photosensitive drum.

A cartridge includes a casing and a photosensitive drum rotatably supported by the casing, with the photosensitive drum having a first end and a second end. A coupling member is provided adjacent to the first end of the photosensitive drum, with the coupling member being operatively connected to the photosensitive drum. The coupling member includes (i) a cylindrical portion, (ii) a first projection at least partially positioned inside of the cylindrical portion, (iii) a second projection at least partially positioned inside of the cylindrical portion, (iv) an elastically movable projection at least partially positioned inside of the cylindrical portion, and (v) a wall extending in a direction perpendicular to the rotational axis and positioned between the second end of the photosensitive drum and the first and second projections.

A Process cartridge includes a photosensitive drum and a coupling member operatively connected to the photosensitive drum, with the coupling member including an arm portion and a projection projecting from the arm portion, the arm portion being capable of transmitting driving force from the projection towards the photosensitive drum. The arm portion of the coupling member extends from a point that is upstream in the rotational direction of the photosensitive drum towards a point that is downstream in the rotation direction of the photosensitive drum.

A drum unit for a cartridge includes a photosensitive drum and a coupling member provided adjacent to an end of the photosensitive drum. The coupling member includes an arm portion, and a projection projected from the arm portion in a direction towards a rotational axis of the coupling member, with a part of the projection inclined relative to the rotational axis of the coupling member. The arm portion extends in a circumferential direction of the coupling member, and, as measured in a direction perpendicular to the rotational axis of the coupling member, a distance between the inclined part of the projection and the rotational axis of the coupling member increases as the distance in the direction of the rotational axis of the coupling member to another end of the photosensitive drum decreases.

A propeller shaft (1), as a power transmitting shaft, of the present invention is configured such that a snap ring (8) as a retaining ring can be inserted inwards into a first penetration slot (31) formed at a tubular portion body (33) of a tubular portion (30) from a radial direction outer side. With this, good workability of assembly of the snap ring (8) is secured. Further, an engagement-stop state of a second shaft (3) by the snap ring (8) can be visually checked from the outside through the first penetration slot (31), then check of an engagement state by the snap ring (8) can be made.

A drive hub includes a body and lugs that extend radially from the body and are engageable with a primemover of a primary power source. The lugs have a fastening lug that includes a radially extending bore. A hybrid, single piece setscrew extends within the bore and has a hemispherical portion configured to apply pressure to engage the drive hub to a shaft of a secondary power source.

A tool assembly includes an elongated handle and a locking system for attaching a tool head to the handle. The tool head can be a floor care tool or other accessory that can be attached to the handle such that the elongated length of the handle can aid in the use of the tool attached. The locking system includes a keyed locking collar for engaging at least a first portion of the tool head, and a locking cap rotatably positioned on the handle for engaging a second portion of the tool head. The handle can be extendable, such as by telescoping, and can also be overmolded.

The torque transmission shaft includes: a shaft that is integrally formed and that has a yoke provided at one end portion in the axial direction and a female serration provided on the inner peripheral surface at the other end in the axial direction; and a clamp that is separate from the shaft and that is capable of reducing the diameter of the other end portion of the shaft in the axial direction; wherein the shaft and the clamp are fixed together.

A propeller shaft assembly comprises a first rotary component having a first splined portion and a first engaging surface arranged transverse to a longitudinal axis of the first rotary component and spaced from the first splined portion and a second rotary component having a second splined portion configured to engage the first splined portion. The second splined portion defines a second engaging surface arranged transverse to the longitudinal axis of the first rotary component. A shear component is disposed between the first engaging surface of the first rotary component and the second engaging surface of the second rotary component. The shear component forms a crash feature of the propeller shaft assembly configured to shear at an edge of the second engaging surface when the first shear component is compressed between the first engaging surface and the second engaging surface.

A quick connect assembly and a retaining member for use in a vehicle. The quick connect assembly includes a first splined member (712) drivingly connected to at least a portion of a second splined member (740). Circumferentially extending along at least a portion of an inner surface (718) of the first splined member is a first splined member retaining member groove (738). The second splined member includes a second splined member retaining member groove (758) circumferentially extending along at least a portion of an outer surface of the second splined member. The second splined member retaining member groove in the second splined member is complementary to and aligned with the first splined member retaining member groove in the first splined member. At least a portion of a retaining member (760) is received and/or retained within at least a portion of the first and second splined member retaining member grooves in the first and second splined members.
