Title:
DRIVE UNIT
Document Type and Number:
WIPO Patent Application WO/2015/111720
Kind Code:
A1
Abstract:
One side, in the axial direction, and the other side, in the axial direction, of a drum (50) around which cables (23, 24) are wound are rotatably supported respectively by a fourth circular-columnar part (39d) provided to a rotor shaft (39) and a cover circular-cylindrical part (32a) provided to a cover (32). Thus, even when a heavy load is applied to the cables (23, 24), the rotor shaft (39) does not tilt. Therefore, this drive unit (30) can operate smoothly, and it is possible to reliably prevent, inter alia, the generation of abnormal noise from the drive unit (30), and early damage to constituent components.
