摘要： PURPOSE:To enable it to support a wheel at the specified position through a simple structure by interposing an expansion cylinder and a cushion unit between a trailing arm supporting the wheel free of rocking motion and a car body, and installing a mechanism locking an axial displacement and its releasing mechanism both in this expansion cylinder. CONSTITUTION:A wheel 40 is supported on a car body 50 free of rocking motion via a trailing arm 43, and an expansion cylinder and a compressed gas-filled cushion unit 16 both are interposed between the trailing arm 43 and the car body 50 in series. In addition, two segments 13 and 14 are installed in an inner part of this expansion cylinder as a mechanism locking the axial displacement of a piston 2 at both the expansion and contraction positions, through which the wheel 40 is locked to a lifting position and a traveling road surface (51) position. At the time of being locked, two subpistons 2B and 2A are displaced to some extent and operates as a lock releasing mechanism only when hydraulic pressure is supplied in an extension direction at the contraction position and in a contraction direction at the extension position.

摘要： PROBLEM TO BE SOLVED: To reduce any vibration produced in the case where a superoconductive magnet has received any dynamic external force by letting a truck frame connect both ends of each crossbeam laid between respective superconductive magnets direct to a part, where a load supporting body of an outer tank is connected, and supporting these superconductive magnets. SOLUTION: A sectional form of a crossbeam 5B of a truck frame supporting and locking both ends of an outer tank 4 is made larger than another ross 5A supporting and locking a center part of the outer tank 4, and also higher in terms of rigidity. The crossbeam 5A is installed in a position equivalent to the enter of a rectilinear part of to inner tanks in center, among four inner tanks, as many as four pieces in total at the outer tank 4. Likewise, the crossbeam 5B is installed in a position equivalent to the center of the rectilinear part of two inner tanks both ends, among four inner tanks, as many as four pieces in total at the outer tank. At this time, the crossbeam 5A of the truck frame comes to be installed in the rectilinear part center of the inner tank becoming a loop of a mode at a time when the inner tank is vibrated by a bending mode in consequence, and thus it is so structured as reducing any vibration in the inner tank.
