Title:
POWER TRANSMISSION MECHANISM AND MULTI-SHAFT DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/046868
Kind Code:
A1
Abstract:
The present invention makes it possible to reduce the force of an employed spring to thereby decrease the amount of abrasion of a power transmission member such as a gear and to control the generation of noise. When a concave part (51) of an outer circumferential surface (52) is placed at a position facing a tip end part (32a) of a pin (32) of a connection shaft (31) by rotating a dial cam (50), the connection shaft (31) which is biased by a coil spring (40) engages with a bevel gear (14) and connects to a rotating bevel gear (35) by way of clutch teeth (33, 36). The connection shaft (31) therefore rotates, and an output shaft (20) rotates together with the connection shaft (31). In other words, drive power is transmitted from a motor (10) to the output shaft (20). Since the coil spring (40) is used to connect the connection shaft (31) to the bevel gear (35), the force of the coil spring (40) can be reduced.
