PROBLEM TO BE SOLVED: To solve problems in a hinge using a coil spring, wherein the energizing force of the coil spring is degraded under use for many years and its end may break depending on the case, and there is a danger of the broken end being mixed in food if the hinge is used for a food processing machine or the like and there is a risk of causing an accident if the hinge is used for automobile parts or the like. SOLUTION: The hinge formed by connecting connection parts of two blades in an openable/closable manner by a connecting shaft is constituted to energize an opening or closing direction force to both blades by a spring wound around the outer periphery of the connecting shaft. The spring is a spiral spring, and its inside locking part is locked to the connecting shaft, while its outside locking part is locked to one of the blades. COPYRIGHT: (C)2010,JPO&INPIT |
