Abstract
One object is to provide a speed reducer provided with a buffer mechanism for reducing an external force and capable of reliably measuring a load torque during an operation. A speed reducing device includes a speed reducing mechanism for reducing a rotation speed of an output with respect to an input between an input rotary shaft and an output rotary shaft, a housing that houses the speed reducing mechanism, and a buffer unit formed of an elastic member and having a cushion force acting mainly in a substantially rotational tangential direction. An amount of displacement of the housing generated by the buffer unit is measured by a measurement device.
