The present invention reduces motor size in a steering device. To this end, this steering device () to be installed in a vehicle has: a power steering unit () positioned below the floor section () of the vehicle compartment (); and a coaxial motor () which is provided directly above the power steering unit () and in a manner such that the output shaft thereof is coaxial with the input shaft of the power steering unit ().

Steering device

A steering device () installed in a vehicle is equipped with: a steering wheel (); a steering shaft () having a first shaft part (), one end of which is directly connected to the steering wheel (), and a second shaft part () connected to the first shaft part () on the other end side thereof; a coaxial motor () which applies a rotational force to the first shaft part (), and has a motor housing () which supports the steering shaft () and surrounds the periphery of the first shaft part (); and a motor securing unit () which, in order to determine the support position of the steering wheel (), secures the motor housing () and a support bracket () secured inside the vehicle compartment.

A steering device () installed in a vehicle is equipped with: a steering wheel (); a steering shaft () having a first shaft part (), one end of which is directly connected to the steering wheel (), and a second shaft part () connected to the first shaft part () on the other end side thereof; a coaxial motor () which applies a rotational force to the first shaft part (), and has a motor housing () which supports the steering shaft () and surrounds the periphery of the first shaft part (); and a support bracket () which extends in the axial direction of the steering shaft () in a front region inside the vehicle compartment, is secured to the vehicle compartment on the bottom end side and top end side thereof, and at the top end side thereof, sandwiches the motor housing () from both the left and right sides in the vehicle widthwise direction.

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.
