Abstract

A starting device (1) comprises a damper mechanism (10), a single-plate lock up clutch (8) that can execute lock-up to couple a front cover (3) and an input shaft of a transmission via the damper mechanism (10), and a centrifugal pendulum vibration absorber that comprises a driven member (15) of the damper mechanism (10) as a supporting member and a plurality of pendulum mass bodies (21). A lock up piston (80) of the lock up clutch (8) and a driving member (11) of the damper mechanism (10) are coupled to each other at a position more to the inside in the radial direction than the plurality of pendulum mass bodies (21) so as to rotate unitedly.

Description

technical field [0001] The present invention relates to a starting device including a vibration damping mechanism, a lock-up clutch, and a centrifugal pendulum type vibration absorbing device. Background technique [0002] In the past, as this starting device, there is known a starting device provided with the following parts: comprising: a multi-disc lock-up clutch comprising a friction plate with a friction plate pasted on both sides of the front and back; The output element of the vibration damping mechanism and the centrifugal pendulum type vibration absorbing device supported by the output element as a vibrator-mass body that freely swings (for example, refer to Patent Document 1). In this starting device, the outer peripheral portion of the friction plate of the lock-up clutch is fitted and connected to the outer peripheral portion of the ring-shaped connecting member (reference numeral 36 ) fixed to the input element of the damping mechanism via rivets. From a fricti...
