ABSTRACT:
In a torque converter with a lock-up mechanism which can decrease a distribution of hydraulic pressure in the radial and circumferential directions of a frictional material, which can prevent the creation of any excess reaction by the distribution of hydraulic pressure, and which can efficiently give a fastening force to the frictional material to thereby improve transmission torque capacity, an oil groove for reducing the distribution of hydraulic pressure is provided on the frictional material or a piston. This oil groove is provided for depressurization at a location which does not hinder the fastening function.
