Abstract

PURPOSE: To shorten the dimension in the axial direction of the automatic speed changing device by a method wherein an oil passageway for introducing a hydraulic pressure supplied from a hydraulic control device to the hydraulic servo of the automatic speed changer is formed in an intermediate supporting wall supporting the journal of an intermediate shaft for the planetary gear type speed changer.
CONSTITUTION: The oil passageway 67 of a radial direction, communicating the output hydraulic port 101 of a hydraulic pressure outputted from the hydraulic control device and the eccentric notch section 65 of a central hole 64, is formed in the intermediate supporting wall 60, and further, the eccentric notch section 65 is communicated with a hydraulic servo 48A through the oil passageway 68 of the radial direction provided in a central tubular section 61. Hydraulic fluid, supplied through the output hydraulic port 101, is supplied to and discharged from the hydraulic servo 48A through the oil passageway 67, the eccentric notch section 65 and the oil passageway 68. Further, the oil passageway 69, supplying the hydraulic fluid to the hydraulic servo 37A or discharging the same from the hydraulic servo 37A through a communicating port 102 provided from the hydraulic control device through a transmission case, is formed in the supporting wall 60.
