Claims

[Scope of utility model registration request]

A cylinder equipped with a locking piece that can be moved in and out with a key and rotatably supported by a casing, and an intermediate cylindrical body that is fitted onto the outside of the cylinder and equipped with an engagement groove into which the locking piece fits. , the cylinder is fitted loosely so as to be movable in the cylinder axial direction between an operating position in which it engages with a transmission part provided on the cylinder and a non-operation position in which it separates rearward from the transmission part and can rotate relative to the cylinder; A locking part opening/closing operating lever that contacts the rear end of the intermediate cylindrical body, a spring that biases and stabilizes the locking part opening/closing operating lever in the operating position, and a spring that holds the intermediate cylindrical body in its normal position and It has a spring and a cam that allow the intermediate cylindrical body to move rearward and rotate integrally with the cylinder when excessive rotational force in the circumferential direction is applied to the intermediate cylindrical body via the locking piece. A cylinder lock comprising an intermediate cylindrical body holding means, wherein the locking portion opening/closing operation lever is pressed and moved from an operating position to a non-operating position by moving the intermediate cylindrical body rearward.
