In addition, it is necessary to ensure a sufficient distance between the front and rear track vehicles (2) and (3) in order to ensure both of the above-mentioned steering actions. There are problems such as the guidance and steering device having a complicated structure and high cost.

(Objectives of the Invention, Means for Solving Problems) The present invention was developed to address the above-mentioned problems in conventional guidance and steering devices for rail vehicles. In the guidance and steering device installed between the rear track vehicles, there is a guide cross beam with common guide wheels at both ends arranged in parallel between the front and rear end surfaces of the front and rear track vehicles, and a guide cross beam with guide wheels at both ends, and a guide cross beam in front and rear from the guide cross beam. A running wheel rotation interlocking mechanism connected to the front and rear running wheels of the track vehicle and rotatably connected between both sides of the front and rear end surfaces to allow horizontal displacement as well as rolling and pitching of the front and rear track vehicles. It is characterized by a structure that includes a pair of guide cross beam support mechanisms that support both sides of the front raising guide cross beam, which is made up of front and rear connecting link members, and is a guide with guide wheels at both ends common between the front and rear track vehicles. A cross beam is provided, and a running wheel turning interlocking mechanism is connected from the guide cross beam between the front and rear running wheels of the front and rear track vehicles, and the front and rear wheels of the front and rear track vehicles are connected to each other.

Guide crossbeam (
20, 21) Although it is displaced relative to K, it can be absorbed structurally.

Furthermore, although Figures 8 and 9 show the curved guide rail (1) (1 case), the guide cross beams (20, 21) always maintain the posture of the front and rear track vehicles (2) and (3). It has the characteristic of maintaining the intermediate position of the angle θ, and the same effect as in the case of one straight guide rail (1) can be obtained.
