A multi-piece gear shift knob and a gear shift lever assembly including the same are disclosed. TA is chosen from a unit obtained from an amino acid, a unit obtained from a lactam and a unit corresponding to the formula \xb7, with a representing the number of carbon atoms of the diamine and b representing the number of carbon atoms of the diacid, a and b each being between 4 and 36, advantageously between 9 and 18,X. Each of the first, second, and third mutually orthogonal axes may form an oblique angle with a longitudinal axis of the projectile body. An internal door part is connected to the outside door panel. A dielectric material 15 is arranged between a back face of a speaker 12 and a feed point 14 of an antenna 13, and electrical length between the human head and the antenna is increased as compared with the structure without the dielectric material 15. In particular, a method and apparatus for making the container are disclosed.
