Abstract: In an airbag-equipped steering wheel, a plurality of horn switch mechanisms assembled to a bag holder each have a securing pin, which is inserted into a corresponding one of through holes formed in a metal core. A clip is engaged with a locking groove of each securing pin, so that each horn switch mechanism is fastened to the metal core.

The inclination permitting portion permits the corresponding securing pin to be inclined about the corresponding clip 13 serving as a fulcrum. In the special through hole, the securing pin is permitted to be inclined about the clip serving as a fulcrum only when the clips are disengaged from the securing pin in all the normal through holes.

Abstract: A pupil detecting apparatus detects an edge of a pupil in an image of a face. An outline of an upper eyelid is also detected. The apparatus selects an effective edge extending along the pupil by removing a part of edge extending along the upper eyelid from the edges detected. Then, the apparatus applies the circle Hough transformation to the effective edge in order to obtain a center of the pupil and a radius of the pupil. Thereby, it is possible to detect the pupil accurately even if a part of the pupil is covered.

Abstract: An object of the invention is to reduce an influence of deviation in pressure increasing performance, which would be caused by individual differences of pressure increase valves, so that a desired braking force may be obtained. A moderate pressure increasing operation is carried out for wheel cylinder pressure of a wheel, which is on a high ?-road, wherein a demand differential pressure for a pressure increase valve is set at a first target pressure for a first time period and then switched to a second target pressure for a second time period. The influence of the deviation may be absorbed during the moderate pressure increasing operation, so that a difference of wheel cylinder pressure between front left and front right wheels may be reduced.
