A multiple disc clutch for an automatic transmission wherein overlapped clutch plates and a piston applying pressure to clutch discs, and a spring retainer supporting a distal end of a spring resiliently supporting the piston are all made of pressed steel, enabling them to reduce their thicknesses, while satisfying a required rigidity. This shortens the entire length of the multiple disc clutch. The entire length of the automatic transmission applied with a multiple disc clutch structure can be shortened to create more space in an engine room.
