Steering apparatus
First Claim
1. A steering apparatus comprising:
- a steering shaft having an end portion coupled to a steering member;
a first housing for rotatably supporting the steering shaft; and
a second housing engaged with the first housing via two impact energy absorbing rings formed separately from each other in an axial direction, so as to be relatively movable in an axial direction, wherein one of the first housing and the second housing has first and second impact energy absorbing protrusions which are projected from positions between the impact energy absorbing rings separately from each other in an axial direction and contact with circumferential surface of the other of the first housing and the second housing.

Abstract
A first housing 3 for rotatably supporting a steering shaft having an end portion coupled to a steering wheel, or a second housing 5 engaged with the first housing 3 via two impact energy absorbing rings 6 and 7 separated in the axial direction so as to be relatively movable in the axial direction, has first and second impact energy absorbing protrusions 8 and 9 projected from positions between the impact energy absorbing rings 6 and 7 separately in the axial direction so as to contact with the circumferential surface of the other of the first housing 3 and the second housing 5. The impact energy absorbing protrusions 8 and 9 therefore can reduce the load applied to the impact energy absorbing rings 6 and 7 in usual steering and the impact energy absorbing rings 6 and 7 can reduce the load due to frictional resistance in impact energy absorption.
