PROBLEM TO BE SOLVED: To provide reduction gears of eccentric rocking type that can detect load actually nearer than before. SOLUTION: This load sensing system is equipped with the eccentric rocking type reduction gears 100, and the load calculation part 320 which computes the load which joins the eccentric rocking type reduction gears 100. The eccentric rocking type reduction gears 100 is composed of the case with inside teeth in the inner circumference, the supporting body supported rotatably by the case, the external gearwheel with the outside gears engaged with the inside gears in the external circumference, the crankshaft which carries out the eccentric rotation of the outside teeth gears to the case according to the rotational movement supported rotatably by the external gearwheel and inputted from external side, and the distortion gauge stuck on the supporting body. Based on the output of the distortion gauge, the load calculation part 320 calculates at least one side of the load which joins the eccentric rocking type reduction gears 100 in the hand of cut around the axis of rotation when the case and the supporting body rotate relatively, and the load which joins the above-mentioned eccentric rocking type reduction gears 100 in the hand of cut centering on the axis of rotation which intersects perpendicularly with the axis of rotation.
