PROBLEM TO BE SOLVED: To provide a high-performance and inexpensive shaking table device in spite of its simple structure. SOLUTION: Two pairs of direct acting block mechanisms 3 moving in one horizontal direction are installed on the upper surface of a base trestle 2, and an intermediate trestle 4 is supported by the direct acting block mechanisms. Two pairs of direct acting block mechanisms 5 moving in another horizontal direction perpendicular to the one horizontal direction are installed on the upper surface of the intermediate trestle, and a vibrating table 6 thereon is supported by the direct acting block mechanisms. The two pairs of direct acting block mechanisms on the base trestle and the two pairs of direct acting block mechanisms on the intermediate trestle are arranged on the same position in a top view. Each one exciting actuator 8 operating in the two perpendicular directions relative to the vibrating table is arranged respectively in the horizontal direction, and each actuator is connected to the vibrating table through the direct acting block mechanisms.
