To provide a tank vehicle capable of suppressing the generation of defective changeover of a valve body.SOLUTION: A tank vehicle includes: a tank; a piping; a direction selector valve 31 disposed in the piping, and having a valve body 46 and a valve drive part for rotating the valve body; driving means having an engagement part to be engaged with the valve drive part, and rotating the valve drive part due to the rotation of the engagement part; a sensor for detecting a rotation quantity of the engagement part; and a control part for controlling the rotation of the engagement part according to a detection result of the sensor. The valve drive part includes a drive shaft part 470 to be rotated by the engagement part, and a guide part 471 for guiding the drive shaft part to a position corresponding to a stop position of the valve body. The drive shaft part is engaged with the engagement part so that the engagement part idles at a prescribed angle from each of a plurality of stop positions to the drive shaft part when being rotated. The guide part includes a fitting part 472 moving with the rotation of the drive shaft part, and a fitting recess having a guide inclined surface for guiding the fitting part, and allowing the fitting part to be fitted to when the valve drive part is positioned in a stop position.SELECTED DRAWING: Figure 6

    【課題】弁体の切替不良が発生することを抑制できるタンク車を提供する。【解決手段】タンクと、配管と、配管に設けられる方向切替弁31であって、弁体46及び、弁体を回動させる弁駆動部を有する方向切替弁と、弁駆動部に係合する係合部を有して、係合部が回動することで弁駆動部を回動させる駆動手段と、係合部の回動量を検知するセンサと、センサの検知結果に応じて係合部の回動を制御する制御部と、を備え、弁駆動部は、係合部によって回動させられる駆動軸部470と、駆動軸部を弁体の停止位置に対応した位置に案内するガイド部471と、を備え、駆動軸部は、回動した際に係合部が駆動軸部に対して複数の停止位置の各々から所定角度空回りするように係合部に係合し、ガイド部は、前記駆動軸部の回動に伴って移動する嵌合部472と、嵌合部を案内するガイド傾斜面を含み、弁駆動部が停止位置に位置したときに嵌合部が嵌合可能な嵌合凹部と、を備える。【選択図】図6
