Abstract
A chassis for video tape recorder molded integrally with a fiber-reinforced plastic composition is light in weight and can meet the requirements for attainment of high precision. It is possible to obtain a chassis with even higher precision and higher rigidity while preventing deformation with time as well as creep deformation, by properly selecting the components of the composition, the number and the position of the gates, and/or the reinforcing measures. In case of using glass fiber as the reinforcing fiber component of the composition, it is desirable to use the type in which 5% by weight or more of the whole glass fiber component is occupied by those glass fibers which have a length of over 1.0 mm and a diameter of 15 .mu.m or less.
