PROBLEM TO BE SOLVED: To ensure safety at the time of starting while a steering handle is turned, without lowering operability and work efficiency. SOLUTION: It is determined whether a turning angle of a steering handle is larger than 45 degrees or not (S1). If the determined result is NO, the turning angle of the steering handle is within a range of 0 to 45 degrees in a right or left direction, and voltage according to an accelerator command value from an accelerator command value outputting portion is applied to execute starting acceleration control under normal condition (S2, S3). On the other hand, if the terming angle of the steering handle is a range not less than 45 degrees in the right or left direction (YES of S1), the accelerator command value from the accelerator command value outputting portion is reduced to half (S4, S5). Then, after shifting to a step S3, the voltage according to the accelerator command value after reduction is applied to a traveling motor (S3), a starting acceleration property is suppressed in generally half as compared with the normal condition.
