1. A stereo camera comprising:
- a first imaging element;
a second imaging element;
a stay;
a first mount surface which is integrally provided with the stay and on which the first imaging element is mounted;
a second mount surface which is integrally provided with the stay and on which the second imaging element is mounted;
a first holding plate, which pushes the first imaging element against the first mount surface; and
a second holding plate, which pushes the second imaging element against the second mount surface;
wherein each of the first and second imaging elements has reference surfaces on adjacent sides for positioning, the stay has positioning surfaces at positions opposed to the reference surfaces, and the first mount surface and the second mount surface are included in substantially the same plane or in substantially parallel planes;
wherein the first and second holding plates are respectively clamped against the first and second mount surfaces integrally provided with the stay and have multiple pawls that push the first and second imaging elements against the positioning surfaces of the stay by contacting adjacent intersecting sides of the first and second imaging elements; and
wherein the first and second holding plates have additional pawls that push the imaging elements against the mount surfaces integrally provided with the stay.

Abstract
Although a conventional method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay. According to this invention, mounting surfaces for mounting left and right imaging elements to a stay are provided to directly position left and right imaging elements to the stay, whereby built-up tolerance between components is reduced and the positional mounting precision between imaging elements is improved.
