Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/132886
Kind Code:
A1
Abstract:
The present invention achieves restriction of the movement of a floating member in the axial direction and increased levels of torsional characteristics in a lock-up device with a simple configuration. Said device is provided with a drive plate (11), a hub flange (12), outer and inner torsion springs (16, 17), an intermediate member (14) for connecting the outer and inner torsion springs (16, 17) in series, a floating member (18), an angle-restricting part (22), and a movement-restricting part (24). The floating member (18) is capable of rotating relative to the outer torsion spring (16) and restricts the movement of the outer torsion spring (16) in the radial direction. The angle-restricting part (22) is formed on the drive plate (11) and the intermediate member (14) and restricts the relative angle of rotation between the drive plate (11) and the intermediate member (14) to a specified angle. The movement-restricting part (24) is formed on the intermediate member (14) and restricts the movement of the floating member (18) in the axial direction.
