The load detecting device according to the present invention has: a load input part having an input surface and an output surface; a strain body having an annular part provided with a contact part forcontacting the output surface, and a support part for supporting the annular part so as to be able to oscillate; an oscillating part for oscillating in response to inputting of a load, the oscillating part being provided to the annular part; an extending part continuous with the oscillating part and extending from the support part, the extending part being provided to the annular part; a sensor for detecting distortion corresponding to a load inputted to the load input part, the sensor being arranged on a back surface on which the contact part is provided in the annular part; and a restricting part at a proximal-end part of the extending part relative to the contact part, the restricting part for restricting deformation of the annular part exceeding a predetermined value when the load inputted to the load input p
