Claims

[Claims for Utility Model Registration] A drive shaft that rotates in response to rotational torque from a drive source, a drum that is freely disposed on the drive shaft and has a rope wound around its circumference, and the drive shaft a spacer floatingly disposed on the drum and integrally fixed to the drum; a drive gear splined to the drive shaft to prevent rotation;
A winch brake device comprising: a snap spring that restricts axial movement of the drive gear; and a brake member that prevents the drum from idling of a clutch member that engages and disengages the spacer and the drive gear, The spacer includes a first member that contacts the side surface of the drum and a second member that engages with the clutch member, and the spacer is arranged on the drive shaft within a groove formed between the first and second members. A brake device for a winch, comprising a disk spline-coupled to prevent rotation, and a resilient member disposed with an expanding force so as to bring the disk into contact with a first rotating member.
