Work vehicle

A work vehicle comprising:

• an engine;
• and
• a transmission unit configured to subject power from the engine to speed change, and output the power,
• the transmission unit having;
• an input shaft to which rotational power is transmitted from the engine;
• a speed change shaft that can be interlocked and connected to the input shaft;
• a power transmission shaft that is interlocked and connected to the speed change shaft;
• a spline mechanism configured to switch, by an outer spline and an inner spline relatively sliding on the speed change shaft in an axial direction of the speed change shaft, between a non-engaged state, in which the outer spline and the inner spline are not meshed with each other and no rotational power is transmitted from the input shaft to the speed change shaft, and an engaged state, in which the outer spline and the inner spline are meshed with each other and rotational power is transmitted from the input shaft to the speed change shaft;
• a gear member that has an engagement recess;
• and
• a claw member that has an engaging claw that engages with the engagement recess and to which rotational power is transmitted,
• wherein both of the gear member and the claw member are disposed on either one of the power transmission shaft or an intermediate shaft provided in a power transmission path leading from the input shaft to the power transmission shaft;
• wherein there are gaps in a rotational direction between the engaging claw and both ends, in the rotational direction, of the engagement recess.
