Claims

[Scope of Claim for Utility Model Registration] (1) A brake cover cylindrical part is formed on the brake cover attached to the side plate of the hoisting machine body, and an inner cylindrical part is supported on the brake cover cylindrical part. is formed at the inner end portion in the axial direction of the cover portion of the operating lever, and a synthetic resin annular member is provided between the inner circumferential surface of the brake cover cylindrical portion and the outer circumferential surface of the inner cylindrical portion. The annular member is slidably interposed, and both axial ends of the annular member are connected to a radially inward flange formed on an axially outer edge of the brake cover cylindrical portion and an axially inner flange of the inner cylindrical portion. A lever hoisting machine, characterized in that the operating lever is slidably engaged with a radially outward flange formed on an end edge, thereby restricting movement of the operating lever in the axial direction. (2) The brake cover cylindrical portion has a cylindrical inner circumferential surface that extends axially outward in parallel to the axis of the drive shaft, and the inner cylindrical portion of the operating lever has a cylindrical inner peripheral surface that extends parallel to the axis of the drive shaft. 2. The annular member according to claim 1, further comprising a cylindrical outer circumferential surface that extends in parallel in the axial direction, and the cylindrical annular member is slidably interposed between the two cylindrical circumferential surfaces. Lever type winding machine. (3) The lever type winding machine according to claim 1 or 2, wherein the radial dimension of the both radial flanges is substantially the same as the wall thickness dimension of the annular member.
