Claims

[Claim for Utility Model Registration] In an inner joint mounting structure for installing an inner joint at the end of a rack shaft of a rack and pinion steering device for automobiles, etc., a threaded portion is formed on the inner and outer periphery of the shaft end, and a threaded portion is formed at a predetermined position on the shaft end. A rack shaft having an engagement recess formed therein, a tapered lock nut that is screwed onto the outer circumferential thread of the rack shaft, forms a tapered pressing surface on the socket side, and has an engagement recess cut out at a predetermined position on the outer circumference; A taper washer that has a tapered surface that matches the tapered pressing surface of the baroque nut and has protrusions integrally formed at two locations on the outer periphery and one location on the inner periphery, and a male thread that connects to the rack shaft at one end of the socket. and a tapered recess on which the tapered washer is fitted on the male screw forming end, and further engages one of the external protrusions of the taper washer at a predetermined position of an outer peripheral protrusion forming the tapered recess. It has an inner joint with a mating recess cut out, and after inserting the tapered lock nut and taper washer together and tightening the male thread of the inner joint to the inner threaded part of the rack shaft, insert the tapered lock nut on the socket side. Press the taper washer into the taper recess of the socket by turning it counterclockwise, and in this pressed state, engage one of the external protrusions of the taper washer with the engagement recess of the socket, and also engage the other of the retaining protrusions with the engagement recess of the taper lock nut. An inner joint mounting structure characterized by having a fixing structure in which the tapered washer is bent and engaged, and an internal protrusion of the taper washer is engaged with an engagement recess formed at the end of the rack shaft.
