る自動変速機のクリープ防止装置。 a starting clutch which is provided in the engine driving force input system via a fluid coupling and is engaged by supplying line pressure when the gear shift position is in the traveling position; a starting clutch hydraulic pressure control means for controlling hydraulic pressure to the starting clutch; and a shift control means for controlling the shift by engaging or releasing a fastening element including a clutch, and when a signal indicating release of the accelerator pedal is input from an input sensor to the shift control means at a predetermined vehicle speed or less at a traveling position, the shift control means shifts to a second or higher speed. 1. A creep prevention device for an automatic transmission, characterized in that the automatic transmission is switched to a creep prevention gear position, and at the same time the starting clutch, which is already engaged, is slidably engaged.
