Claims

[Scope of utility model registration request]

In a steering device including a pinion gear that rotates in conjunction with a steering wheel, and a rack gear that meshes with the pinion gear and slides left and right, a pinion shaft extending from the pinion gear is provided with a pinion gear that rotates in response to rotation of the pinion shaft. A guide that moves forward and backward is provided, pistons facing each other are arranged between the guide and the shaft housing, a spring is elastically loaded between the inner end surfaces of the piston, and a stopper that comes into contact with the pair of pistons is provided between the guide and the shaft housing. By providing it in the shaft housing, a reaction force chamber is formed whose volume changes according to the amount of rotation of the pinion shaft when it rotates from the straight-ahead neutral position, and the reaction force chamber is pressurized in accordance with the vehicle speed. A steering force control mechanism for a steering device, characterized in that it is configured to introduce a medium.
