PURPOSE: A motion bed moves on a plane or in a space maintaining equal inertial load to each axis by combining single-shaft actuators driven independently to each other. CONSTITUTION: A motion bed comprises a bed(12), a first linear actuator(14), a first linear bearing(18), a second linear actuator(16) and a second linear bearing(20). The first linear actuator(14) moves the bed(12) by a first axis and comprises a fixed member(142) and a moving member(144) moving linearly to the fixed member(142). The first linear bearing(18) is installed between the moving member(144) of the first linear actuator(14) and the bed(12) to guide the bed(12) to move by a second axis. The second linear actuator(16) moves the bed(12) by the second axis and comprises a fixed member(162) and a moving member(164) moving linearly to the fixed member(162). The second linear bearing(20) is installed between the moving member(164) of the second linear actuator(16) and the bed(12) to guide the bed(12) to move by the first axis.
