Title:
ELECTRICALLY-OPERATED STEERING COLUMN DEVICE
Document Type and Number:
Japanese Patent JP2008302753
Kind Code:
A
Abstract:

To provide a compact electrically-operated steering column device that can secure the free movement of a steering column while improving supporting rigidity.

Since a first threaded shaft 12 and a second threaded shaft 22 are in parallel with a steering shaft S, the size of the electrically-operated steering column device can be made compact in a direction perpendicular to the steering shaft S. Since a first motor 11 and a second motor 21 are arranged between the first threaded shaft 12 and the second threaded shaft 22 so as to align axes of the motors, the compact steering column device can be provided. By arranging the axis-aligned two motors 12 and 22 below or above a column body 1, the compact steering column device can be provided eliminated in lateral hang-over from the steering shaft S.
