Abstract: In a sheet bundle folding apparatus for folding a bundle of sheets in two, a stick-out plate for sticking the bundle of sheets is adapted to reliably stick the bundle of sheets folded while being held between rollers for folding the bundle of sheets in a folding position therefor. A first folding roller is positionally fixed. A second folding roller is movable toward and away from the first folding roller. The stick-out plate sticks the bundle of sheets and pushes it into between the first and second folding rollers. At this time, the rollers of the stick-out plate roll along a groove. The forward roller is fitted in the groove with a correction allowance above it, and is downwardly biased by a spring. The stick-out plate follows the folding position for the bundle of sheets.

Abstract: A collapsible steering column apparatus comprises a steering column capable of receiving, a steering shaft having one end to which a steering wheel is fixed; and an energy absorbing member composed of a plastically deformable material and having its front end joined to a partial outer peripheral surface of the steering column and its rear end joined to a portion fixed to a vehicle body. The energy absorbing member is formed by punching out a sheet of metal plate to achieve a laterally undulating configuration with the extent of the undulations laterally of the energy absorbing member varying along its length. When applying an impulsive force to thrust the steering column forward due to a secondary shock in a collision, the energy absorbing member permits a forward displacement of the steering column while being plastically deformed in such a direction as to extend the undulations thereof.
