  • Coupling/uncoupling device
    Patent number: 11518550
    Abstract: A coupling/uncoupling device includes a columnar member configured by a divided pair of semicircular members, and a pair of coupling members forming a circular holding section that holds the columnar member. The circular holding section includes a circular inner surface section with which an outer circumferential surface of the columnar member is in slide contact, the circular inner surface section being formed from inner circumferential surfaces of a semicircular section in one coupling member and a semicircular section in the other coupling member. The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position where a contact surface of the pair of coupling members and a dividing surface of the columnar member are flush with each other.
