<P>PROBLEM TO BE SOLVED: To provide such a structure that a steering wheel can be smoothly displaced forward upon generation of a secondary collision even in the case where the structure has an electrically-driven motor 13a which is one component of an electric power steering device and is installed in a sideway projecting state. <P>SOLUTION: The dimensions of a pair of left and right mounting plates 17e, 17f mounted on a column-side bracket 10d supported on a steering column 6c are made different from each other on the right and left. More specifically, a distance Le between the center of the steering column 6c and the center of a bolt 34 for supporting the mounting plate 17f on the motor 13a side is set to be shorter than a distance Lf on the non-motor 13a side. The rate of a break-off load applied to the installation side of the motor 13a having the short distance Le is increased. The inertial mass of the motor 13a allows the installation side of the motor 13a to have difficulty in dropping off forward as compensation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
