A vehicle body includes a vehicle body frame and a steering rotation unit that is supported on the vehicle body frame and that rotates about a steering axis. The vehicle includes a variable trail length mechanism. The variable trail length mechanism varies a trail length of a front wheel and includes an oscillation unit and a torsion reduction portion. The oscillation unit is connected with the steering rotation unit so as to be oscillatable in a fore-aft direction and supports the front wheel. The torsion reduction portion reduces torsion of the oscillation unit in a vehicle width direction through the oscillation unit combined with the steering rotation unit under a condition in which the trail length is changed such that the front wheel is disposed at a rearmost position.
