Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047546
Kind Code:
A1
Abstract:
Provided is a power transmission device wherein tooth contact noise is suppressed using a simple configuration. This device comprises an input plate (10), a flange (11), and a torsion spring (12). The input plate (10) has a catch (10b) and is adapted such that torque is applied thereto. The flange (11) has a groove (14e) which can engage with the catch (10b) with a predetermined gap therebetween in the rotational direction. The flange (11) is disposed next to the input plate (10) in the axial direction and outputs torque. The torsion spring (12) is disposed between the input plate (10) and the flange (11), can elastically deform an amount greater than the gap between the catch (10b) and the groove (14e), and presses the input plate (10) and/or the flange (11) in the rotational direction.
