Claims

[Scope of Claim for Utility Model Registration] An internal sun gear 1, a planetary gear 2 that meshes with the sun gear, and fixed substrates 3 provided on both sides of the gear train consisting of the sun gear and the planetary gears, respectively. A main shaft 5 is rotatably supported between the two fixed substrates in a bilaterally supported manner, and a rotary shaft that coincides with the rotation center of the sun gear is a main shaft 5, a crank pin 6 is a rotary shaft provided at the rotation center of the planetary gear, A crankshaft 4 whose crank arm length is the eccentric distance S of the crank pin with respect to the main shaft, and three or more crankshafts arranged at equal intervals around the main shaft and which connect and fix the fixed boards on both sides together. The planetary gear is arranged at equal intervals on the circumference of a predetermined radius from the center thereof, and has a through hole 8 through which the corresponding fixing pin passes, and the radius of the through hole is equal to the corresponding one. The eccentric distance S is larger than the radius of the fixed pin, and one of the fixed base plates on both sides is fixed to a fixed member such as the building side, and the other fixed base plate is provided with a shaft that drives the main shaft. An electric motor with a reduction gear, characterized in that an electric motor 12 is installed.
