1. A slat having a truss structure moved along track belts, the slat comprising:
a main body comprising a stepping part configured to receive a load of a user and coupling parts formed at both ends of the stepping part so as to be fixed to the track belts; and
a truss part connected to the stepping part so as to distribute the load applied to the mart body,
wherein the truss part comprises a chord member part spatially spaced apart from the stepping part by a first designated distance, and a diagonal member part configured to connect the chord member part and the stepping part,
wherein the diagonal member part comprises first unit diagonal members configured to connect an inner surface of the chord member part to the stepping part, each of the first unit diagonal members comprising at least one first diagonal member inclined in a first direction and arranged in a length direction of the chord member part and the stepping part, and at least one second diagonal member inclined in a second direction opposite to the first direction and arranged in the length direction of the chord member part and the stepping part,
wherein one side of the least one first diagonal member is connected to one side of the at least one second diagonal member, and one sides and remaining sides of the at least one first diagonal member and the at least one second diagonal member are respectively connected to the stepping part and the chord member part so as to form a triangular truss structure,
wherein the diagonal member part further comprises second unit diagonal members provided adjacent to the first unit diagonal members and configured to connect ends of the chord member part to the stepping part and the coupling parts, and
wherein the outermost second diagonal member of the first unit diagonal member and the innermost first diagonal member of the second unit diagonal member are spaced apart from each other by a second designated distance to be opposite each other.
