<P>PROBLEM TO BE SOLVED: To achieve a large stroke of slide while attaining miniaturization in relation to a spring unit using compression coil springs. Ž<P>SOLUTION: The spring unit includes: a slide case 20 and a guide case 30 which are mutually slidable; slide guide pins 40 whose one side ends are respectively fixed to slide guide pin fixing parts 22 formed on both side positions of the slide case 20; spring guide pins 50 whose one side ends are respectively fixed to spring guide pin fixing parts 23 formed at the slide case 20; compression coil springs 60 mounted on the spring guide pins 50 respectively; slide guide pin holding parts 32 formed at the guide case 30 to slidably hold the slide guide pins 40 respectively; and spring guide pin holding parts 33 formed at the guide case 30 to movably hold the spring guide pins 50 respectively. The slide guide pin holding parts 32 are constructed in such a way that they protrude toward the slide case 20 than the spring guide pin holding parts 33. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
