A gaming machine for playing a card-based wagering game. Each of coding units codes one of the component pictures into an intra-picture prediction coded picture or an inter-picture prediction coded picture, and outputs a bit stream corresponding to the component picture. At least one of the outer tubes is divided into a first tube and a second tube between which a length adjusting mechanism is interposed. Both ends of each of the protrusions 10 converge into an inlet port for high temperature fluid 58a and an outlet port for high temperature fluid 58b, respectively. The Ti\u2014Al\u2014V shell carries a UHMW polyethylene insert, which is locked by interference, a non-circular post mated with an elongated opening and a circumferential locking groove mated with an interior projection.
