<p>PURPOSE:To make the assembly space of a planetary gear device compact by arranging an elastic member enerigizing a bearing member to the steering shaft side in the recessed section of fitting recessed formed on the outer periphery of a boss plate or between the recess of the boss plate and the center of the steering wheel. CONSTITUTION:Fitting recesses provided at symmetrical positions on the outer periphery of boss plate 4 have a fixed width, and further a recessed section 13a is formed in the center of the bottom so that a bearing member 15 can be coupled. The bearing member 15 has a lub 20 protruding outward in the radial direction in its cener, and through holes are formed on both sides. A knock pin 22 and a bolt 23 are erected at the bottom of the fitting recesses 13 of the boss plate 4 by loosely penetrating the holes 21. Coil springs 24 are inserted outside the knock pin 22 and the bolt 23 and energize a planetrary shaft 14 via the bearing member 15 in the radial direction toward the steering shaft 2.</p> |
