摘要:
A drive frame 34 as a cylindrical molded article has a drive frame main body 34a, three first cam grooves 34c, three second cam grooves 34d, three high-density regions H, and three cam pins 43. The cam pins 43 are disposed in the circumferential direction between first center lines X1 which are positioned in the center in the circumferential direction between adjacent high-density regions H, and the high-density regions H.

An injection mold 70 includes a first portion 71, a second portion 72, a third portion 73, and a fourth portion 79. The first portion 71 has three high-density regions H in which there is the highest proportion of the axial direction dimension accounted for by the portion corresponding to cam grooves with respect to the axial direction dimension of a cavity 71a. First gates 74b are disposed at locations corresponding to the high-density regions H, or closer to the high-density regions H than second gates 75b. The average channel sectional area of first runners 74a is larger than the average channel sectional area of second runners 75a.

Provided is a flat display device comprising an outer cabinet in a frame shape, wherein at least one side of a frame section of the outer cabinet includes a decorative bar, which is formed by sequentially laminating a second member transmitting light and a third member having a smaller refractive index than that of the second member on a first member having a reflecting surface to reflect light, and is provided with a light-emitting unit, which emits light, in a portion opposed to an end surface of the second member of the decorative bar.

A drive frame 34 serving as a cylindrical molded article includes a drive frame main body 34a, three first cam grooves 34c, three second cam grooves 34d, three first gate portions 84b, and three high-density regions H. The first gate portions are formed at the end of the cylindrical portion, and are vestiges of gates in injection molding. The high-density regions H are regions in which there is the highest proportion of the axial direction dimension accounted for by the first cam grooves 34c and the second cam grooves 34d with respect to the axial direction dimension of the drive frame main body 34a. The first gate portions 84b are disposed at a location closer to one of two adjacent high-density regions than the other in the circumferential direction of the two adjacent high-density regions H.
