PURPOSE:To prevent the occurrence of the slip of a belt, by a method wherein the hydraulic pump of a transmission is coupled to the engine of a vehicle through a first one-way clutch, and is coupled to a member to be driven in a power transmission route, running from a main clutch to driving wheels, through a second one-way clutch. CONSTITUTION:An engine 10 is coupled to a belt type transmission 16 through a main clutch 14, and a driving shaft 48 of a hydraulic pump 40 is operatively coupled to the engine 10 of a vehicle through a first one-way clutch 54. The driving shaft is operatively coupled to a rotary shaft 18 on the primary side, being a member to be driven, of a power transmission route, running from the main clutch 14 to driving wheels, through a second one-way clutch 56. This causes a hydraulic pump to be driven by the second one-way clutch even during release of the main clutch from engagement, maintains power transmission capability, and prevents the occurrence of the slip of a belt. |
