Title:
DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2019127997
Kind Code:
A
Abstract:
To provide a driving device capable of reliably performing a turning on/off function of a coupling turning on/off transmission of a rotation force from a first rotation body to a second rotation body, and restraining collision noise of the coupling and the first rotation body during turning on/off.SOLUTION: A driving device comprises a first rotation body supported by a support shaft so that it can be drive-rotated in normal and reverse directions, a second rotation body, and a coupling 53. A first latchet claw 61 and a second latchet claw are respectively at a first opposite part 75 of the coupling 53 and a second opposite part of the second rotation body. A cam is provided at one of a third opposite part 76 of the coupling 53 and a fourth opposite part of the second rotation body, and a cam surface 74M is provided at the other of the parts. When the first rotation body is drive-rotated in a reverse direction, a state for turning off the transmission of the rotation force is set. A convex part 70 projects on one of an end surface 83 of the third opposite part 76 of the coupling 53 and an end face of the fourth opposite part, so that the convex part 70 comes into contact with the other end surface under a condition for turning off the transmission of the rotation force.SELECTED DRAWING: Figure 12
