MAGNETIC LEVITATION LINEAR MOTOR TRAIN TRACK JOINT GAP ADJUSTER

PROBLEM TO BE SOLVED: To provide a track joint gap device capable of absorbing a large amount of track beam expansion while finely maintaining vehicle roadability at low cost in a magnetic levitation linear motor train system. SOLUTION: A moving frame 70 is mounted on one of adjoining track beams capable of making displacement in the longitudinal direction of a track and in a state to control the displacement by friction. A first joint gap rail 3a is fixed to the moving frame 70. A second joint gap 3b is installed between a main rail 3 supported on the track beams and the end of the first joint gap rail 3a in a state to float from the track beams. Both ends of the second joint gap rail 3b are connected to the main rail 3 and the end of the first joint gap rail 3a with a connecting means 8 so as to enable them to relatively make displacement in the longitudinal direction of a rail and to disenable them to relatively make displacement in the latitudinal direction of the rail and in the vertical direction.
