PROBLEM TO BE SOLVED: To provide a working vehicle which improves vibration control property of a working section height adjusting mechanism.SOLUTION: A working vehicle includes a working section height adjusting mechanism 24 which is capable of adjusting a height in a gravity axis direction with respect to a chassis of a working section connected to a prime mover 22 mounted on a chassis 12a. The working section height adjusting mechanism includes: a tubular-shaped frame section 80 a prime mover housing 82 which can be inserted into the frame section and is constituted of an inside housing 82a and an outside housing 82b a plurality of guide plates 84 which can be respectively arranged in a space 841 which is formed by a pair of projection sections 82b1 and 82b2 formed at different positions in a circumferential direction in the radial direction of the outside housing and a projection section 801 formed at a corresponding position in the circumferential direction in the radial direction of the frame section and an energization member 86 which is arranged between the guide plate and the outside housing so as to energize the outside housing toward the guide plate.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】作業部高さ調節機構の防振性を向上させるようにした作業車両を提供する。【解決手段】シャシ12aに登載される原動機22に連結される作業部のシャシに対する重力軸方向の高さを調節可能な作業部高さ調節機構24を備えた作業車両において、作業部高さ調節機構が、筒状形状を呈するフレーム部80と、フレーム部の内部に挿入可能で、内側ハウジング82aと外側ハウジング82bからなる原動機ハウジング82と、外側ハウジングの径方向に周方向において異なる位置に形成される1組の凸部82b1,82b2とフレーム部の径方向に周方向の対応する位置に形成される1個の凸部801で形成される空間841にそれぞれ配置可能な複数個のガイドプレート84と、ガイドプレートと外側ハウジングの間に配置されて外側ハウジングをガイドプレートに向けて付勢する付勢部材86とを備える。【選択図】図5
