摘要： A collapsible telescopic steering apparatus includes a steering column having an outer tube and an inner tube. The tubes can be switched between a press-fit state and a loose-fit state. The position of a steering wheel is adjusted by way of relative sliding movement of the loose-fitted tubes along an axial direction thereof. A shock absorbing projection is provided on at least one of an inner periphery of the outer tube and an outer periphery of the inner tube, as confronting to the counterpart tube. The shock absorbing projection is normally spaced away from the counterpart tube but is deformed as pressed against the counterpart tube in association with relative sliding movement of the press-fitted tubes upon collision, thereby absorbing the shock of the collision.

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 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： In a press belt (2), stepped portions are formed between an outer peripheral surface of a central region (A) and outer peripheral surfaces of end-corresponding regions (B) located so as to corresponding to both ends in a lateral direction of a press roll (1) or a pressure shoe (3), so that the end-corresponding regions have a smaller thickness than the central region. The outer peripheral surfaces of the end-corresponding regions are finished so that a processing flaw depth becomes 10 μm or less.

摘要： An electric power steering apparatus includes a reduction gear mechanism (17) for reducing the rotation speed of an output shaft (16) of an electric motor (15). The reduction gear mechanism (17) comprises an inscribed gear (39) rotatable interlockingly with the output shaft (16), and a circumscribed gear (40) in which the inscribed gear (39) is inscribed. An endless belt connects a driving pulley (41) integrally rotatable with the circumscribed gear (40) and a driven pulley (42) disposed so as to surround a steerable shaft. By heightening the reduction gear ratio by the speed reduction using the inscribed gear (39) and the circumscribed gear (40), the reduction gear mechanism (17) as a whole can achieve a high reduction gear ratio without making the diameter of the driving pulley (41) very small.

摘要： A detecting unit for detecting a torque applied to a rotor according to rotation of the rotor having an input shaft and an output shaft connected with each other by a torsion bar and a detection circuit board connected with the detecting unit are molded with synthetic resin material to form a mold member. The installation of the mold member into a housing, which has a cylinder portion to surround the rotor and a retainer having an opening formed at the peripheral wall of the cylinder portion, is achieved by inserting the mold member into the retainer from the radial direction through the opening of the retainer.
