PROBLEM TO BE SOLVED: To easily provide a required light distributing performance and enhance the appearance observed from the outside by providing such a structure as to vertically and laterally diffuse and reflect the light from a light source bulb toward the front. SOLUTION: The surface of each reflecting surface element (s) constituting a lamp body inner surface is made into a saddle form (a sectional form having a vertically recessed curve and a horizontally protruding curve) (a). The thicknesses in the central part and peripheral part (particularly, corner part) of the reflecting surface element (s) can be thus uniformed, compared with a case (b) having a protruding surface form (or recessed surface form) as in the past, and the flow of a fused resin in the molding of the lamp body is improved, whereby each reflectting surface element (s) can be precisely formed. When the lamp observing angle is changed from the lamp front view, the bright part (spotliahted part) of the reflecting surface element (S) is moved in a different direction according to the moving direction of the point of view, whereby the novelty in design is ensured. |
