Abstract
An optical distance measuring equipment in which light from a light emission element is transmitted to an object through a light transmission lens, and light reflected on the object is received by a light reception element through a light reception lens so that a distance to the object is measured on the basis of light transmitting timing and light receiving timing. In the optical distance measuring equipment, a lens holding member for disposing the light transmission lens and the light reception lens substantially at the same distance relative to the light emission element and the light reception element respectively is provided in front of a light transmission/reception board on which the light emission element and the light reception element are installed.
