Claims

[Scope of utility model registration request]

A pinion rotatably supported by a pinion casing, a rack rod having rack teeth that mesh with the pinion, a plunger inside the casing that slides and supports the rack rod, and a spring that presses the plunger toward the rack rod. In the rack-mounted steering device, the plunger is composed of a sliding surface material made of a synthetic resin having self-lubricating properties and a plunger base holding the sliding surface material, a sliding surface for slidingly supporting the rack rod; and a surface opposite to the sliding surface that is orthogonal to the axial direction of the rack rod, and has an apex in the center, and a peripheral edge extending from the apex in the axial direction of the rack rod. A chevron-shaped surface portion is formed on the plunger base, and the plunger base is perpendicular to the axial direction of the rack rod and is deep in the center and gradually becomes shallower toward both sides.
1. A rack and pinion type steering device, characterized in that a concave surface portion having a shaped bottom is formed, and the sliding surface material is held by fitting the chevron-shaped surface portion into the concave surface portion of the plunger base.
