Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a push button device that implements a smooth button operation, and desired light shielding and mechanical strength by keeping clearance between light shield walls and button operation parts almost unchanged during button operations irrespective of part dimensional tolerance, assembly accuracy and the like. SOLUTION: The push button device 1 integrally comprises: a button base part 59 fixed to a housing 34; resilient elements 60 extended for flexible deformation from the button base part 59; and the button operation parts 42 attached to the tips of the resilient elements 60. The button base part 59 is integrated with the light shield walls 63 for preventing leakage of light emitted from LEDs 45 arranged behind the push button device 1. COPYRIGHT: (C)2007,JPO&INPIT
