CLUTCH, DRIVE TRANSMISSION, AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2018204785
Kind Code:
A
Abstract:
To provide an easy and low-cost configuration of a clutch.SOLUTION: The present invention includes: an input member; a rotational output member to which an input torque from the input member is transmitted; a stationary member having a cylindrical inner wall face surrounding the input member and output member and attached to an attached part by restricting a rotation thereof; and a contact member which can be in contact with the input member, output member, and stationary member. The output member has an output contact part which is in contact with the input member, and the contact member is positioned between the output member and the stationary member and includes: an arc-shaped first contact face that contacts with the cylindrical inner wall face of the stationary member; and a second contact face that contacts with the output contact part. When the input torque for rotating the input member is input, the output member and the contact member contacts with the input member to rotate. When a reverse input torque for rotating the output member is input, the output member moves apart from the input member and the output contact part of the output member stops a rotation of the output member by pressing the second contact face of the contact member to press the first contact face against the stationary member.SELECTED DRAWING: Figure 10
