Abstract:
1. An optical distance-measuring device that measures a distance to an object subject to distance measurement, comprising: a light-emitting element mounted on a mounting member; a light-emitting lens that irradiates the object subject to distance measurement with light emitted from the light-emitting element; a light-receiving element, mounted on the mounting member, that detects a position of convergence of light reflected by the object subject to distance measurement; a light-receiving lens that causes the reflected light to converge onto the light-receiving element; light-transmitting resin members that causes the light-emitting element and the light-receiving element to be sealed therewith; a first light-shielding resin member that covers the light-transmitting resin member so as to form an interior space that allows the light emitted from the light-emitting element to reach the light-emitting lens and an interior space that allows the reflected light entered from the light-receiving lens to reach the light-receiving element; a lens frame, formed from the metal, that retains the light-emitting lens and the light-receiving lens; and a second light-shielding resin member that causes the first light-shielding resin member to be sealed therewith and retains the lens frame together with the first light-shielding resin member, the lens frame having through holes, one of the first light-shielding resin member and the second light-shielding resin member having projections that project toward the other resin member, the other resin member being connected with jutting parts of the respective projections in such a state that the projections pass through the corresponding through holes and jut from the lens frame.
