摘要： A collapsible telescopic steering apparatus comprises a steering column having an inner tube and an outer tube which are engaged with each other. The engagement state of the tubes is switchable between a press-fit state and a loose-fit state. Upon vehicle collision, the tubes in the press-fit state are slid relative to each other for shock absorption. For telescopic adjustment, the tubes in the loose-fit state are slid relative to each other to adjust the fore-and-aft position of a steering wheel.

摘要： A vehicular steering apparatus includes a column bracket secured to a steering column; and a fixing bracket secured to a vehicle body. The column bracket includes a top plate and a pair of side plates. The fixing bracket supports the column bracket via a support shaft. A support-shaft through hole formed in each of the side plates of the column bracket includes a slot extended along a longitudinal direction of the steering column. A resilient member is interposed between the top plate of the column bracket and a confronting portion of the support shaft. The resilient member biases the support shaft along a predetermined biasing direction to restrict play of the support shaft in the slot.

摘要： A power transmission apparatus for vehicle capable of obtaining a plurality of transmission characteristics by moving spools of variable throttle member 6 according to controlling current flowing to a driving coil 7 by steps, wherein a spool chamber 60 housing a first and second spools 61, 62 therein is communicated with discharge side of a vane pump 3 according to first and second communicating holes 54, 55. And by controlling current flowing to the driving coil 7 by steps, two kinds of magnetic fields, intense and weak are formed in the spool chamber 60. In the case where the first spool 61 moves to the position where it is contacted with the inside end of the spool chamber 60 by the action of the weak magnetic field, it closes an opening end of one communicating hole 54, and in the case where the second spool 62 moves to the position where it is contacted with the first spool 61, it opens an opening end of the other communicating hole 55. Three kinds of different transmission characteristics are obtained in the above mentioned cases and case of current cutoff, and the positions of the first and second spools 61, 62 do not vary in the respective cases. Thereby, positional variation caused at spools are prevented and the respective transmission characteristics are stabilized.
