<P>PROBLEM TO BE SOLVED: To solve a problem that it requires a high assembly precision to assemble a lens to a case so that its light guide face may be in closely opposed state to an LED lamp fixed. <P>SOLUTION: A level difference portion 15 is provided on an inner circumference face of a side wall of a case 11, and an engaging portion of a light guide body 25 (for example, periphery portion of light guide face 27) of a lens 20 is engaged with this level difference portion 15, thereby, positioning of the lens to the axial direction of the case 11 is performed. Since the LED lens is fixed to the case, that is, it is positioned in the axial direction, positioning of the light guide face 27 of the lens 20 and the LED lamp 30 is made automatically, and it does not require a special alignment work when the lens 20 is assembled to the case 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
