Abstract
A support for an automatic transmission. The support has a tubular supporting portion having an inner peripheral surface supporting a transmission shaft and an outer peripheral surface supporting an inner cylindrical portion of a hydraulic servo drum of the transmission. The support has working oil passages formed therein and adapted for supplying and discharging a working oil to and from the hydraulic servo drum. The support has a support body including a first oil passage leading from an oil pressure controller for supplying and discharging working oil and communicating with the inner periphery of the tubular supporting portion, a second oil passage providing a communication between the outer periphery and the inner periphery of the tubular supporting portion and an inner oil groove providing a communication between inner peripheral openings of the first and second oil passages. The support further has an inner sleeve fitting on the inner peripheral surface of the tubular supporting portion to cover the oil groove thereby forming an oil passage for working oil, and an outer sleeve fitting on the outer periphery of the tubular supporting portion, the outer sleeve being provided with a sleeve hole aligned with a working oil port formed in the inner cylindrical portion of the hydraulic servo drum and communicating with an outer peripheral opening of the second oil passage. The outer sleeve is further provided in the outer peripheral surface thereof with ring grooves formed at both sides of the sleeve hole and adapted to receive seal rings.
