Abstract
PURPOSE:To reduce the axial size of a piston of a hydraulic servo for driving a multiple disks engaging apparatus, by forming on the outer circumferential side a projected annular plane as a pressing part to said engaging apparatus, and mounting oil seals on the outer and inner circumferential sides. CONSTITUTION:A piston 1 consists of an annular plate 2, inner and outer seal support plates 4, 3, an outer back-up ring 5, an outer lip seal 6 and an inner lip seal 7. The annular plate 2 has on the outer circumferential side the projected annular plane 21 projecting toward the clutch side and acting as a pressing part to the engaging apparatus such as a multiple disks clutch or the like, and also has an annular recess 22 inside of the plane 21 that acts as a return spring anchoring section, and the annular recess 22 is formed with a plurality of return spring holding projections 24 that are shaped by pressing. Lip seals 6, 7 are clamped by fitting seal support plates 3, 4 to said annular plane 21 and an inner end 23.
