Title:
DRIVING FORCE TRANSMISSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/038131
Kind Code:
A3
Abstract:
A driving force transmission apparatus includes a damper device (20) that includes: a plurality of elastic bodies (21) provided between a first member (10), to which driving force is transmitted from a driving source, and a second member (30) transmitting the driving force to a fluid transmission device (40); an outer coupling portion (25a, 26a) integrally rotatably coupled to a radially outer portion (12) of the first member (10); and an inner coupling portion (27a, 28a) integrally rotatably coupled to a radially inner portion of the second member (30). The damper device (20) transmits driving force, transmitted to the first member (10), from the outer coupling portion (25a, 26a) to the inner coupling portion (27a, 28a) via the plurality of elastic bodies (21) and then to the second member (30). One of the outer coupling portion (25a, 26a) and the inner coupling portion (27a, 28a) of the damper device (20) is fixedly coupled via a highly rigid portion (29) and the other one is axially movable along a rotation axis (X).
