PROBLEM TO BE SOLVED: To prevent a substrate provided with a light emitting element and a cell structure provided with an opening part for passing light of the light emitting element through from being disabled to be assembled to a support body.SOLUTION: A headlight 4 for travel comprises: a support body 10; positioning pins 13, 14 provided to the support body 10; a substrate 50 mounted on the support body 10; a plurality of light emitting elements 21 to 29 mounted on the substrate 50; a first circular fitting hole 53 which is formed in the substrate 50 and in which a first positioning pin 13 is fitted; a second circular fitting hole 54 which is formed in the substrate 50 and into which a second positioning pin 14 is inserted; a cell structure 60 mounted on the support body 10 over the substrate 50; a third fitting hole 83 formed in the cell structure 60; and a fourth fitting hole 84 which is formed in the cell structure 60 and into which the second positioning pin 14 is inserted. The second positioning pin 14 has clearance with the fitting holes 54, 84 in radial directions of the engagement holes 53, 83.SELECTED DRAWING: Figure 4 |
