Claims

[Scope of Claim for Utility Model Registration] (1) A steering shaft, which has a pinion gear fixed to its lower side and rotates in response to the steering force of the steering wheel, is inserted from above the steering gear housing and meshes with the pinion gear. A steering gear structure comprising a steering gear housing and a rack gear arranged to be movable back and forth in the vehicle width direction in a cylinder connected to the steering gear housing as the pinion gear rotates. A sealed gap is formed between the above-mentioned rack gear located at an appropriate position and the cylinder, and an end bush that abuts the outer peripheral surface of the rack gear, and an outer peripheral end bush located on the radially outer side of the end bush. A rack gear consisting of an end cover whose other end is fitted into the open end of the cylinder, and a resin mold layer injected and solidified into the gap formed between the end bush and the end cover. A steering gear structure characterized by having a supporting member. (2) A steering shaft, which has a pinion gear fixed to its lower side and rotates in response to the steering force of the steering wheel, is inserted from above the steering gear housing, and is meshed with the pinion gear to allow rotation of the pinion gear. Accordingly, in a steering gear structure comprising a steering gear housing and a rack gear arranged to be movable back and forth in the vehicle width direction within a cylinder connected to the terminal part of the steering gear housing, the terminal part of the steering gear housing and the cylinder. and the connecting portion are fitted together by forming a sealed gap in the radial direction of both, and a resin mold layer is injected and solidified into the gap formed between the terminal portion and the connecting portion. A steering gear structure featuring:
