A tilt steering apparatus includes a steering column having a tube member housing a steering shaft and rotatably installed on a body frame for tilt about a steering column tilt axis. Between a steering gearbox and the steering shaft, the apparatus includes a first universal joint secured to the steering shaft, an intermediate shaft and a second universal joint. The first universal joint includes a swing center defining a steering shaft tilt axis. Bearings rotatably support the steering shaft within the steering column tube and elastic members engage with the bearings to flex for axial movement of the steering shaft in the steering column tube. This relative movement accommodates an offset between the steering shaft and steering column tilt axes, thereby avoiding an increase in thrust load between the shaft and column during tilt for improved steerability.

A steering system includes a column jacket including a lower jacket and an upper jacket; an engagement member; a retaining member; and a buffer member that is retained by the retaining member and contacts the engagement member in a contact direction at a time when the upper jacket is displaced to one sliding end. The retaining member includes a support surface that supports the buffer member; paired holding portions that are respectively disposed on both sides of the buffer member in a circumferential direction of the upper jacket and hold the buffer member toward the support surface; and a restriction portion configured to be engaged with an end of the butler member on a side toward which an opposite direction is directed, so as to restrict movement of the buffer member in the opposite direction, the opposite direction being opposite to the contact direction.

A steering device according to an aspect of the present disclosure includes: a column unit configured to rotatably support a steering shaft; a front bracket configured to rotatably support the column unit; a lock bolt configured to protrude in a right-left direction from the column unit; a rear bracket that includes a tilt guide hole and is attached to a vehicle body behind the front bracket, the tilt guide hole guiding the lock bolt to move upward and downward as the column unit rotates around an axis; and a connection piece bridged between the front bracket and the rear bracket in a state of being fixed to each of the front bracket and the rear bracket.

The invention aims at providing a work vehicle in which an operator can easily view each of switches in spite of the work vehicle in which a plurality of switches such as a DPF regeneration switch, a working switch and a one-touch automatic switch are concentrically provided on a front surface of a control seat. In a work vehicle having a cabin which is inward provided with a control seat installed in a travel machine body, a DPF regeneration switch, a working switch, and a one-touch automatic switch are provided. The DPF regeneration switch is provided on an upper surface of a steering column in a base portion of a control steering wheel, and the DPF regeneration switch is arranged in a field of vision of an operator under a straight moving work posture.
