A hollow structural component which includes an integral structure, partition walls intersecting each other within the integral structure, and a plurality of independent hollow portions formed as specified by the partition walls so as to be arranged within the integral structure. The integral structure is formed into one piece by one-shot molding or by one injection molding die which is caused to slide against each other between its stationary side and movable side for post-forming, whereby weight reduction of the hollow structural component, reduction in the amount of resin used, reduction in the number of parts involved, and improvement in the workability for assembling may be achieved with consequent cost reduction.

A vibration or shock absorbing member which is composed of a material capable of effecting injection molding such as plastics, rubber, ceramics, metallic powder mixed and kneaded with a specified binder, or glass powder mixed and kneaded with a specified binder, and includes an integral structure, a plurality of protrusions formed at least on one main flat surface of the integral structure, and a plurality of independent hollow portions provided symmetrically or in an aligned state within the integral structure through intersecting partition walls. Such integral structure is molded as one unit by one-shot molding (molding at one time) or by a single molding die for expanding the range of selection for materials and spring constants so as to achieve freedom in the choice of shapes and reduction in weight.

Vibration or shock absorbing member

The present invention relates to a structure of positioning a cathode ray tube in a cabinet of a television receiver. In the television receiver, at least one portion of each of front window frames of the cabinet for positioning the cathode ray tube therein is formed as to be elastically deformable outwardly due to a contacting relationship between the cathode ray tube and the cabinet when assembling them. Because at least one portion of each of the front window frames is elastically deformed, a variation in a dimensional relationship between the cabinet and the cathode ray tube caused when securing the cathode ray tube to the cabinet can be compensated. Preferably, the front window frame is formed in such a manner that a thickness thereof is gradually reduced from the proximal end toward the free end.
