Abstract

A washer (76) of thickness (t) is disposed between the locking piston (80) and the outer extension (71) of the output hub (7), and the opposite surface (30a) of the washer (76) from the front cover (3) ) and the third distance (L3) in the axial direction of the cover side contact surface (31a) of the cylindrical part (31) minus the front end surface (83a) of the friction member (83) and the surface of the lock piston (80) (80a), the first distance (L1) in the axial direction, the axial distance between the casing side abutment surface (40a) of the pump casing (40) and the surface (71a) of the outer extension (71) of the output hub (7) The value (L3-(L1+L2+t)) obtained by the sum of the second distance (L2) on the gasket (76) and the thickness (t) in the axial direction of the gasket (76) is within a predetermined range greater than zero.

Description

technical field [0001] The present invention relates to a starting device and a method of manufacturing the same. Background technique [0002] Conventionally, as such a starting device, a starting device including a front cover connected to an engine, a pump impeller rotating integrally with the front cover, a turbine wheel arranged opposite to the pump impeller and connected to an output hub, A damper for attenuating vibration between the output hub and a lock-up clutch for locking and unlocking the front cover and the output hub via the damper (for example, refer to Patent Document 1). The lock-up clutch is constituted as a single-plate hydraulic clutch, and has a lock-up piston supported by an output hub so as to be movable in the axial direction of the starter, and a friction member attached to the front cover-side surface of the outer periphery of the lock-up piston . In this starter device, a spacer is provided between the lockup piston and the output hub to adjust ...
