Abstract
A steering apparatus (2, 202) of the invention of the present application is disclosed, which includes an electrifying plate (40, 240) secured to an inner column (11, 211) and received within a guide groove (25, 225) of an outer column (10, 210). The electrifying plate contacts an electrifying cover (15, 215) of the outer column, and configures part of an electrifying path leading to the outer column from the inner column. The invention of the present application enables a new electrifying path to be ensured, which extends from a steering wheel (101) to a car body (100).
Claims20
A steering apparatus comprising:
- a steering shaft having conductivity and transferring a steering force;
- an outer column having the conductivity, including a guide groove extending in an axial direction and receiving insertion of the steering shaft on the radially inner side;
- an inner column having the conductivity, being fitted in the outer column to enable a relative movement in the axial direction, and supporting the steering shaft rotatably on the radially inner side;
- a guide member being received in the guide groove and fitted to the inner column;
- a fixture securing the guide member to the inner column;
- an electrifying cover having the conductivity and covering at least part of the guide groove from the radially outer side of the outer column;
- and
- an electrifying plate having the conductivity, being fixed to the inner column in contact with at least one of the fixture and the inner column, and having at least a portion becoming elastically deformed to contact the electrifying cover under a predetermined contact pressure.
