Claim:
1. A steering apparatus, comprising: a steering shaft made of a material having conductivity, the steering shaft including a fitting portion transmitting steering force and being extendable in an axial direction, the fitting portion being applied with a resin coating; an outer column made of a material having conductivity, the outer column rotatably supporting the steering shaft, the outer column being provided with a guide groove formed therethrough in a radial direction and extending in an axial direction and a pair of guide walls projecting outward in the radial direction and extending along the guide groove on both sides of the guide groove; an inner column made of a material having conductivity, said inner column being fitted in said outer column to enable relative movement to each other in said axial direction, and rotatably supporting said steering shaft; a resin coating applied to an inner peripheral surface of said outer column, or an outer peripheral surface of said inner column; a guide member made of a resin, the guide member being received in said guide groove and slidingly in contact with the guide walls, the guide member being attached to said inner column; an electricity-carrying plate made of a metal plate having conductivity, the electricity-carrying plate being attached to said inner column together with the guide member, the electricity-carrying plate having a pair of contact pieces elastically deformed and in contact with insides of said pair of guide walls at a predetermined contact pressure; and a metal fitting having conductivity, the metal fitting being in contact with the inner column and fixing the electricity-carrying plate together with the guide member to the inner column.
