Abstract

PURPOSE: To obtain an inexpensive, miniature and lightweight chassis while preventing its resonance, curvature and creep deformation by using two kinds of chassis, formed of different kinds of resin, superposing upon each other.
CONSTITUTION: Of a video tape recorder chassis of double-layer structure fabricated by forming main chassis 1 and subchassis 2 of different kinds of resin, chassis 1 and subchassis 2 come into direct contact only where screw 3 is fixed. Since chassis 1 and subchassis 2 are provided with ribs 8a and 8b and extremely small gap D is made between chassis 1 and 2, ribs 8a and 8b meet chassis 1 or subchassis 2 to provide reinforcement against deformation of larger than gap D even when either of chassis 1 and subchassis 2 causes creep deformation, thereby preventing the deformation.
