PROBLEM TO BE SOLVED: To provide a working vehicle equipped with a chemical-scattering device hardly having the risk of a boom being damaged by the contact of the tip part of a side boom with a wall or the like of a barn at such the time of going into or out of a barn which is a narrow space, even having the boom to be stored along the longitudinal direction of a vehicle body.SOLUTION: The traveling adaptability when going into or out of the narrow barn or when traveling on a narrow crank road is extremely improved than the conventional one because the side boom 9b can be turned by about 90° outward from a boom-storing position, and also the side boom 9b can be turned to the inside of the boom-storing position by an arbitrary prescribed angle from the boom-storing position, and the minimum turning radius of the working vehicle is made smaller while preventing the damage by the interference of the right and left side booms 9b and 9b with each other to enable the small turn because the angle of the maximum inward turning of the side boom 9b is restricted to the position at which the right and left side booms 9b and 9b are not interferes with each other.COPYRIGHT: (C)2011,JPO&INPIT【課題】車体の長手方向に沿って収納されるブームであっても、狭い空間である納屋での作業車の出入り時等においてサイドブーム先端部が納屋の壁等にブームが当たって損傷するおそれがない薬液散布装置を備えた作業車を提供すること。【解決手段】サイドブーム9bをブーム収納位置から外側に略90度回動させことと、サイドブーム9bをブーム収納位置からブーム収納位置より内側に任意の所定角度で回動させることができるため、作業車を狭い納屋への作業車の出入りや狭いクランク路の走行適応性が大幅に従来より向上し、またサイドブーム9bの最大の内回動の角度は、左右のサイドブーム9bが互いに干渉しない位置までとしたので、左右のサイドブーム9b,9b同士の干渉による損傷を防止しながら、より作業車の最小半径を小さくでき、小回りが可能となる。【選択図】図2
