A skate board is provided to transfer a power perfectly by rotation of a short connection shaft without twist and elasticity of rubbers generated from a lower end of the board, and to reduce a manufacturing cost by differing a mounting position of a caster on the board manufactured by one forming unit. The skate board includes: a front board(10) and a rear board(20) formed to be separated by being mutually spaced; casters(50) rotatably mounted on a mounting part(51) of the bottom of the respective boards, and having respective bracket(50a) with a regular slope; and a short connection shaft(30) connecting the respective proximal ends of the front and rear board, and having locking parts(31) formed on both ends thereof. The connection shaft is unmovably fixed to the boards by wrapping the locking parts with rubbers(40,40a), inputting the rubbers in receiving parts(11) formed under the respective proximal ends of the boards, and covering them with caps(11a).
