Patent ID: 7410190

Claim:
A motor-driven position adjustment apparatus for a steering wheel comprising: a steering column with a steering shaft rotatably supported inside; a driven member joined to a part of the steering column; a push-pull rod which is arranged in the axial direction of the steering column in a state where one end is joined to the driven member; a driving member that is rotatably supported on the periphery of a part toward the other end of the push-pull rod, and that displaces the push-pull rod in the axial direction of the steering column as it rotates; and an electric motor for rotating and driving the driving member, and the steering column being displaced based on a relative displacement of the driving member and the push-pull rod based on a current supplied to the electric motor to adjust a position of a steering wheel supported on an end of the steering shaft, wherein at least either one of a joined part between the push-pull rod and the driven member, and a joined part between the driven member and the steering column, can be separated based on a shock load applied at the time of a collision, and wherein the separable joined part includes a pair of members to be joined, which are fitted via an elastic deformable spacer.
