Japanese Patent JP2020070185
Kind Code:
A
Abstract:
To provide a winding device that can reduce the device size along the axial direction of the drum and realize a smaller and lighter device.SOLUTION: The winding device is provided with a tubular connecting portion 53b having an outer circumference 53d and an inner circumference 53e at the center of rotation of a carrier 53, and is equipped with a needle bearing 54 that connects the outer circumference 53d to a drum shaft 63b of a drum unit 63 in such a way that power can be transmitted, and that rotatably supports a carrier support portion 46b of a motor shaft 46 in the inner circumference 53e. As a result, the carrier 53 and the drum unit 63 can be rotated in one piece, and the bearing between the drum and the rotating shaft, which was necessary in the conventional structure, can be omitted. Therefore, the dimensions of an electric winch 30 along the axial direction of the drum unit 63 can be shortened, and a smaller and lighter device size can be achieved.SELECTED DRAWING: Figure 4
