ABSTRACT:
A lift arm (9) includes a first arm (11) and a second arm (12). A pivot joint portion (32) where the first arm (11) is pivoted on a bracket (8) stood at a vehicle side portion substantially corresponds to the rear end of an operation control portion. A rod (15) as a swing motion-limiting member is interposed between the bracket (8) and the second arm (12). An angle of bend formed by the first arm (11) and the second arm (12) is set to be large at a lowered position of the lift arm and small at a lifted position.
