の安全装置。 In the power transmission path of the winch, the torque transmission member for transmitting torque from the driving side to the driven side is rotatable with respect to either the driving side member or the driven side member and in the axial direction. While they are slidably fitted, they are opposed to the other member with a plane orthogonal to the axis, and one of the opposing planes between the torque transmission member and the other member is fitted in the circumferential direction. Several engagement grooves are formed, and the other is provided with an engagement member that can be engaged and detached from the engagement groove, and the torque transmission member is always pressed axially toward the other member by an elastic member. By doing so, the engagement of the engagement member with the engagement groove is maintained, and when an overload is applied to the driven side member, the torque transmission member is retracted in the axial direction against the elastic member, so that the engagement member is A mechanical winch safety device configured to escape from the engagement groove.
