While comprising filled minor compartments being filled with an inclusion in which a liquid makes the major component, and vacant minor compartments being filled with the air, at least one of the vacant minor compartments adjoins the filled minor compartments, and a fragile section is formed in at least one of ribs that demarcate the filled minor compartments and the adjoining vacant minor compartments. After the fragile section has fractured, shock energy can be absorbed furthermore by means of circulation resistance to the inclusion that flows from the filled minor compartments to the vacant minor compartments.

Shock absorbing apparatus

The present invention provides a radio wave transmission cover, which is provided in front of a radar device for vehicles, and a method of manufacturing the radio wave transmission cover. In the radio wave transmission cover, cover-side wall surfaces () are formed in a second cover layer () at positions adjacent to each other. Furthermore, substrate-side wall surfaces (), which have shapes complementary to the cover-side wall surfaces (), are formed in a substrate layer (), which is provided on the rear surface of the second cover layer (). The cover-side wall surfaces () and the corresponding substrate-side wall surfaces () are engaged to each other.

A bumper molding is fabricated by disposing segmented anodesandon surfacesandof a base material, which are to be plated, and performing electroplating so as to form metal films on the surfacesand, respectively. The curvature of a surface of a concave portion, which is formed in each part of the surfacesandso that the surface of the concave portion is away from the segmented anodesand, respectively, is larger than those of other portions at a part serving as a border between the second plated surfaceand the fourth plated surface. Accordingly, the distance from the part serving as the border between the second plated surfaceand the fourth plated surfaceto a metal casecorresponding to this part is set so as to be shorter than those from each of the other parts to the metal casesandrespectively corresponding to the segmented anodesand

Method for fabricating plated product

A second metal moldhas a through holethat extends in the movement direction of the second metal mold. A first metal moldhas an internal threaded portionthat extends on a common line with the through holeand has an opening at the surface of the first metal moldfacing the second metal mold. A boltformed by a shaftand a headis employed. The shaftis passed through the through holein such a manner that the headis arranged at the opposite side to the first metal moldwith respect to the second metal mold, and the distal end of the shaftis located at the same side as the first metal moldwith respect to the second metal mold. When the second metal moldis held in contact with the first metal mold, the boltis rotated by an electric motorthrough the head. In this manner, an external thread, which is formed at the distal end of the shaft, is threaded to the internal threadsof the internal threaded portion. This presses the second metal moldagainst the first metal mold
