A cab mounting apparatus for a vehicle includes a front mount connecting between a front side of a cab and a chassis. A rear mount connects between a rear side of the cab and the chassis. The front mount includes a stabilizer link disposed on a front side of the vehicle, a pair of front brackets individually fixed to the front side of the cab, and a pair of connecting arms individually connecting between respective ends of the stabilizer link and the respective front brackets. Each connecting arm is pivotally connected to each front bracket by a hinge member and a bush. The bush has a pair of stopper members disposed on both ends thereof. The bush and the pair of stopper members are integrated into a single unitary body.

A steering device exhibiting improved layout properties around a steering shaft. A steering device installed in a vehicle, the vehicle compartment of which is capable of tilting, has: a first steering shaft, one end of which is connected to a steering wheel; a second steering shaft positioned below the first steering shaft and in a manner such that the one end thereof connected to the other end of the first steering shaft is located above the floor section of the vehicle compartment; and a coaxial motor which applies a rotational force to the first steering shaft and is provided in a manner such that the output shaft thereof is coaxial with the first steering shaft. Furthermore, the second steering shaft is capable of telescoping, because a shaft and a cylindrical member are connected so as to be capable of sliding relative to one another in the axial direction.

The steering angles of front wheels 3f and rear wheels 3r of a vehicle 1 can be respectively controlled by a front wheel steering angle control actuator 35 and a rear wheel steering angle control actuator 44. If a steering wheel 20 is operated in a turning direction of the vehicle 1 while the vehicle 1 is traveling in a straight line, then a controller 60 changes the steering angle of the front wheels 3f to approach to a steering angle specified on the basis of an operation amount after the steering wheel 20 is operated, and also controls the front wheel steering angle control actuator 35 and the rear wheel steering angle control actuator 44 to change the steering angles of the rear wheels 3r to the opposite direction of the turning direction of the vehicle 1 immediately after the steering wheel 20 is operated.
