The present invention provides a production method and an apparatus for double curve formed products for producing double curve formed products easily at low cost, stabilizing an accuracy in configurational dimension of the double curve formed product and improving an accuracy in assembly thereof, the production apparatus being of a simple construction apparatus. Around an inner die in which an end portion of a treatment product is engaged, an outer die in which the other end portion of the treatment product is engaged is rotated relative to each other at predetermined angles. At this time, a side face of the treatment product is curved so that it is successively folded back. By a deformation reaction caused at this time, the side face of this curved portion is pressed against a processing curved surface of the inner die such that the side face is deformed along the processing curved surface. Another side face of the treatment product is pressed against a processing curved surface of the outer die such that it is deformed along the processing curved surface. As a result, in the treatment product, one curved surface is formed along the processing curved surface of the outer die and the other curved surface which is continuous from the one curved surface which is folded back is formed along the processing curved surface of the inner die.

The present invention provides a grease for a slide contact which comprises 100 parts by weight of a synthetic base oil which contains synthetic poly-.alpha.-olefin oil mixture as a main ingredient consisting of synthetic poly-.alpha.-olefin oil having a low viscosity of from 8 to 30 cSt (40.degree. C.) and synthetic poly-.alpha.-olefin oil having a high viscosity of 470 cSt (40 .degree. C.), 0.1-10 parts by weight of fine particulate clay mineral having micropores and/or fine particulate clay mineral structure having monolayers capable of intercalating water or anions, 5-25 parts by weight of thickener consisting of 12-hydroxy lithium stearate and lithium stearate in a weight ratio of from 20:1 to 5: 1, and 0.1-2.0 parts by weight of a phenolic primary antioxidant. The grease according to the present invention is particularly suitable as a grease for a slide contact of the sliding switch of vehicles such as an automobile.

A sideview mirror for automobiles includes a half mirror, a regulating filter mounted in opposed relation to a backside of the half mirror and a light-emitting diode for applying light to the regulating filter. The half mirror has both light reflecting and transmitting characteristics. The regulating filter is so arranged that only part of the light from the light-emitting diode is allowed to pass through the regulating filter to be thereby directed toward a following vehicle and that the remainder of the light from the light-emitting diode is prevented from passing through the regulating filter. Since an image reflected on the half mirror is overlapped with the part of the light from the light-emitting diode, the contrast of the image is reduced.
