PURPOSE: A checker for a hinged door is provided to be easily mounted on a narrow hinge device and to minimize the deformation due to abrasion and friction in a long-term usage. CONSTITUTION: A checker for a hinged door comprises a hinge hole (31), a guide slot hole (32), a first expansion and contraction hole (33), a V-shaped elastic piece (34), an inner side elastic piece (35), a pressing unit (36), and a second expansion and contraction hole (37). The hinge hole is hinged to a checker shaft. The guide slot hole is attached with a control rod with a predetermined distance to guide the control rod. The first expansion and contraction hole is formed on a predetermined position in the guide slot hole in vertical and longitudinal directions. The V-shaped elastic piece is formed on the top end of the first expansion and contraction hole towards the inside bottom. The width of the inner side elastic piece becomes gradually narrow. The pressing unit is formed at the tip end of the inner side elastic piece to press and cover the control rod. The second expansion and contraction hole is formed at the tip end of the guide slot hole and is extended to the bottom of the inner side elastic piece by making a circle with the pressing unit. |
