SHOCK ABSORBING ELECTRIC POWER STEERING DEVICE FOR VEHICLE

摘要

An annular dust seal (30) sliding against the outer peripheral surface of a large diameter section (4b) of a lower shaft (4)(input shaft) is installed in the inner peripheral wall of a lower column (2). In the inner peripheral wall of the lower column (2), there is no annular positioning section (31), constructed as a projection, a shoulder, a step, or other form, or the annular positioning section (31) is provided spaced from a dust seal or is provided in contact with the vehicle front side of the vehicle. In a secondary collision, the dust seal (30) can move to the front of the vehicle together with an upper column (1), etc. even after the upper column (1) comes in contact with the dust seal (30), and impact energy can be absorbed by rigidity of the dust seal (30).
