Claims

[Claims for Utility Model Registration] (1) A rack shaft that is driven in the left-right direction of the vehicle as the pinion gear rotates connected to the steering wheel, a gear housing that movably houses the rack shaft, and the gear housing. and a support member that supports the gear housing on the vehicle body via an elastic member, the elastic member being a variable-rigidity elastic member whose supporting rigidity of the gear housing can be changed by an external control command to an actuator. The support rigidity control means outputs a control command to the actuator from the outside, and includes a steering wheel operation detection section that detects whether the steering wheel is being turned into a steering wheel, a steering wheel turning back, or a steering wheel is being held; A steering gear housing support device characterized by using a control means having a support rigidity control section that outputs a control command to increase the stiffness of the steering wheel, and a support rigidity control section that outputs a control command to lower the support rigidity when the steering wheel is turned back and when the steering wheel is held. (2) The variable rigidity elastic member defines the inside of the elastic body into left and right fluid chambers, and communicates the left and right fluid chambers through a solenoid valve as an actuator, and opens and closes the solenoid valve. 2. The steering gear housing support device according to claim 1, wherein the support rigidity is a member that can be switched between high rigidity and low rigidity. (3) The steering wheel operation detecting section is a detecting section that detects whether the steering wheel is being turned into the steering wheel, the steering wheel is turned back, or the steering wheel is being held by determining whether the steering angular velocity and the vehicle lateral acceleration are positive or negative. Item 2. The steering gear housing support device according to item 2.
