Abstract

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.

Claims2

Dependent claims

A steering device to be mounted on a vehicle having a tiltable vehicle cabin, the steering device comprising:

a first steering shaft connected at one end to a steering wheel;
a second steering shaft disposed below the first steering shaft and connected at one end to another end of the first steering shaft via a first joint part, the one end of the second steering shaft being located above a floor of the tillable vehicle cabin;
a third steering shaft connected to another end of the second steering shaft via a second joint part disposed below the floor;
and
a coaxial motor including an output shaft arranged coaxially with the first steering shaft, the coaxial motor applying a rotational force to the first steering shaft,
a cylindrical upper cover covering peripherally the first steering shaft;
and
a cylindrical lower cover having an upper end connected to a lower end of the upper cover and a lower end fixed to the floor of the vehicle cabin, wherein
the second steering shaft is extendible and retractable in an axial direction.
