PROBLEM TO BE SOLVED: To provide a snow sliding tool wherein traveling property is stable and durability of a board is improved by securing flexibility of the center part of a front board and a rear board. SOLUTION: On the upper surface of the front board 29, a connection member 10 with a shaft 31 as its front end and a shaft 32 as its rear end is fitted in the longitudinal direction of the board. The bearings 33 and 35 of the connection member 10 are rotatably fitted to the shafts 31 and 32. The connection member 10 has a structure of fitting a cylindrical body 10a where a rubber O-ring 2a is mounted to a cylindrical outer peripheral surface and a cylindrical body 10b where a rubber O-ring 2b is mounted a cylindrical inner peripheral surface to each other. A spring is mounted to the base of the cylindrical body 10b. The fitting part of the connection member 10 is movable so as to properly extend and contract forward and backward in the direction of an arrow in Fig. The extension and contraction of the connection member 10 can be adjusted by varying positions of fixing the shafts 31 and 32 to the board.
