Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a work vehicle capable of suppressing occurrence of shock.SOLUTION: A work vehicle includes: a hydraulic static transmission provided in a travel transmission device configured to transmit power from an engine to a drive wheel; an actuator configured to rotate a trunnion shaft of the hydraulic static transmission; a brake pedal sensor configured to detect a depressed amount of a brake pedal; and a control unit configured to, when the brake pedal is depressed, make a position of the trunnion shaft close to a neutral position where power is not transmitted in the hydraulic static transmission, and as the depressed amount of the brake pedal is made larger, make a rotational speed of the trunnion shaft higher.SELECTED DRAWING: Figure 11 【課題】ショックが発生することを抑制する作業車両を提供すること。【解決手段】エンジンから駆動輪へ動力を伝達する走行伝達装置に設けられた油圧式無段変速装置と、油圧式無段変速装置のトラニオン軸を回動させるアクチュエータと、ブレーキペダルの踏み込み量を検出するブレーキペダルセンサと、ブレーキペダルが踏み込まれた場合に、トラニオン軸の位置を油圧式無段変速装置において動力伝達が行われない中立位置に近づけ、ブレーキペダルの踏み込み量が大きくなるほど、トラニオン軸の回動速度を大きくする制御部と、を備える。【選択図】図１１
