摘要： An image forming device includes a tripod type constant-velocity joint through which a rotary member shaft of a rotary member is connected to the drive shaft of a motor. The constant-velocity joint includes a pair of outer rings each having three axially extending track grooves in its inner periphery, and a tripod member having three protrusions formed on each of the axial ends thereof and axially slidably received in the corresponding track grooves. The outer rings and the tripod member are formed of synthetic resin. One of the outer rings and the tripod member are inseparably coupled to the drive shaft so that the other of the outer rings is always disconnected from the tripod member when the rotary member is pulled away from the motor.

摘要： A rotary drive device includes a drive motor and drive transmission portion, which transmits a rotational drive force of the motor to a driven rotor and includes three or more drive transmission members. A high stiffness member is attached to a low-stiffness drive transmission member, which is one, lower in stiffness, of two of the drive transmission members, to increase stiffness of the low-stiffness drive transmission member. The two form a drive transmission point corresponding to a resonant point of a lowest resonance frequency among frequencies at a plurality of resonance points in frequency response characteristics derived from rotation information. One drive transmission point, which is on either a drive-transmission input side or output side, other than the drive transmission point corresponding to the resonant point of the lowest resonance frequency, of the low-stiffness drive transmission member is configured to transmit the rotational drive force through the high stiffness member.
