The invneiton disclsoes a riding machine that includes: a base frame, a swinging mechanism, and a movable support, wherein the movable support is pivoted to the base frame through the swinging mechanism, so that the movable frame can move like wave front and back relative to the base frame through the swinging mechanism, that can form a movement like riding a horse. The base frame is incliend with a lower head and a higher tail, wherein included angle between the slope line of the base frame and horizontal surface is 3-15 degrees, so that due to the upwardly inclined included angle on the base frame backwardly, the gravity center of the whole riding machine is descended forwardly, and a vertical component force is generated so that a constrain force forms on the base frame of the riding machine. During movement, horizontal component force is reduced effectively, and a problem of raising of the base frame is prevented, what is more, damage on parts due to vibration displacement is avoided, so that the riding machine is more safe and comfortable.
