A forklift includes a vehicle and a cargo handling device. The cargo handling device includes a mast, a lift bracket, and a pair of forks that includes claw portions, the forks being separated from each other in a vehicle width direction. The vehicle includes a vehicle main body, and a pair of straddle legs that is provided such that the straddle legs extend to the front side from a lower portion of the vehicle main body and the cargo handling device is interposed between the straddle legs in the vehicle width direction and that supports the mast such that the cargo handling device is movable forward and backward between an advance position and a retreat position, and front ends of the claw portions are positioned behind front ends of the straddle legs when the cargo handling device is at the retreat position.

In a scroll fluid machine, a thinned section () is provided in correspondence with a position at which the wrap height of a spiral wrap (B,B) changes due to a step part. The thinned section () is provided on the front-side surface or the rear-side surface of a tooth tip section of at least one of the spiral wraps (B,B) of at least one of partner scrolls () respectively engaging with scrolls (). The thinned section () is provided in the direction in which the wrap thickness decreases so as to extend over at least a reduced-machining-accuracy area (), which is an area where the machining becomes discontinuous due to at least a change in the wrap height. Thus, a contact failure between the spiral wraps (B,B) is avoided in the area where the machining accuracy relatively decreases as a result of increasing the machining speed, thereby achieving both improved productivity and maintained performance.
