Zusammenfassung:	Provided is a lens mounting structure capable of reducing the number of positioning holes (21) in an LED substrate (20) without increasing the center alignment error between an LED (10) on the LED substrate (20) and a lens (30) fixed to a housing (40). This lens mounting structure is provided with: an LED substrate (20) on which a plurality of LEDs (10) are mounted, the LED substrate (20) having positioning holes (21) of the same number as a plurality of housings (40); a plurality of housings (40) that are disposed on the LED substrate (20) and have protrusions (41) that engage with the positioning holes (21); a lens (30) fixed to the housing (40); and a cover (60) that holds the lens (30) and the light emission side of the housing (40), the housing (40) being connected to an adjacent housing (40) by means of connecting parts (42, 43), being positioned by the engagement of the positioning hole (21) and the protrusion (41) and the connection by means of the connecting parts (42, 43), and being held in a positi
