Zusammenfassung:PURPOSE:To smooth inching at an easy drive system carrying fork lift track, by arranging so that the liquid pressure retaining valve of a slope start auxiliary device may be opened and braking may be released when the stepping on of a clutch pedal is detected. CONSTITUTION:When a slope start auxiliary means 10 detects the release of an accelerating pedal 1, the release of the drive of a clutch 7, the stepping on of a brake pedal 4 and the neutral range shift of a select bar, a brake retaining signal is outputted to a slope start auxiliary device 6. As a result, a liquid pressure retaining valve 5 comes into a closing posture and liquid pressure is retained, and the force of braking is retained even if the brake pedal 4 is released. And when inching is made by stepping on a clutch pedal 8 before the stepping on of the accelerating pedal 1, a brake release means 11 output a brake release signal, and the force of braking is released. Thus, a start at a slope becomes smooth.
