Abstract: A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

Abstract: A method for forming tear lines in the rear side of an automobile interior article having a cover portion being developed from which an airbag inflates. When either an automobile interior article body having an integrally molded surface portion or an automobile interior article surface portion is to be molded, the mold is opened after tear line forming projections are moved forward and backward with the mold closed. Thus, the tear lines can be formed at the molding time without any visible extrusion marks of the tear line forming projections on the front surface side (the design face).

Abstract: In order to enhance the fatigue resistance and the anti-seizure property while maintaining the embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer is provided with a recess “a” and protrusions “b”, thereby being made into a textured uneven surface. The protrusion has the shape of a oblique square at 45° relating to the circumferential direction, so that when a foreign particle X introduced between sliding surfaces of a shaft and the plain bearing is moved in the circumferential direction in accordance with the rotation of the shaft, the foreign particle X runs against a side edge of the protrusion “b” and moves along the side edge, thereby the embedding of the foreign particle X is promoted. If the foreign particle fails to be adequately embedded, the foreign particle leaves the side edge again.

Abstract: In order to provide a plain bearing excellent in the anti-seizure property, a bearing metal layer is provided with a plurality of recesses different in depth on the inner surface thereof so as to form an uneven textured portion thereon, the recesses being filled with a soft overlay layer. At the beginning of the use, the overlay layer develops the conformability. When the wear proceeds to the wear level I so that the shallow recesses disappear, an intermediate layer or the bearing metal layer forming protrusions is exposed and form a condition in which the overlay is mixed. Furthermore, when the wear proceeds to the wear level II, the shallow recesses disappear while the deep recesses remain, so that the condition hardly to cause the seizure is maintained.

Abstract: In order to enhance the fatigue resistance and the anti-seizure property while maintaining the. embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer which are formed on the inner surface of a back metal in this order. The inner surface of the bearing alloy layer is provided with a recess groove “a” extending in the circumferential direction, so that the inner surface is made into a textured uneven condition. The recess groove “a” has a bent portion which is bent relative to the circumferential direction, so that a foreign substance X entering between a mating shaft and the plain bearing is moved in the circumferential direction owing to the rotation of the shaft, the foreign substance X runs against a side edge of the recess groove “a” and moves along the side edge, thereby the embedding of the foreign substance into the overlay layer is promoted.
