式変速装置。 In a hydraulic clutch type transmission device in which a plurality of hydraulic clutches are disposed on a transmission path and the transmission is performed by selective engagement of the hydraulic clutches, a transition period control valve is provided between the hydraulic clutch and the transmission control valve V, The transition period control valve is composed of a control spool with a throttle that throttles the amount of return oil from the hydraulic clutch, and a control piston that prevents the control spool from moving in the closing direction due to the return oil, and the control piston has one end connected to the control spool. 1. A hydraulic clutch type transmission, characterized in that pressure oil from a clutch port of a low gear is introduced through an oil passage into an oil chamber at the other end.
