PROBLEM TO BE SOLVED: To provide a planetary gear reduction gear or a planetary roller reduction gear having the function of accurately measuring load torque applied on a planetary gear reduction gear. SOLUTION: In a configuration in which load torque applied on a planetary gear reduction gear is taken out as a force in a normal direction applied on an internal gear 14, the internal gear 14 is received by a ball bearing 12 to reduce the rotation friction of the internal gear 14. The reduction gear is provided with a shaft 1 for transmitting the force in the normal direction of the internal gear 14. The shaft 1 is received by a needle roller bearing 4. The force in the normal direction of the internal gear 14 is detected by a load cell 2 through the medium of the needle roller bearing 4 and a lever 3. COPYRIGHT: (C)2004,JPO
