Abstract: An optical displacement sensor in an external-force detecting device comprises a light source, an optical sensor, and a light reflecting means. The light source and the optical sensor are disposed at an action section of the device adapted to receive an external force, and the light reflecting means is disposed at a support section of the device adapted to support the action section via elastic spoke sections, and light emitted from the light source is reflected at the light reflecting means and received at the optical sensor whereby displacement of the action section relative to the support section is detected for calculation of an external force applied.
