Claims

[Scope of utility model registration request]

a main body built into and fixed to the door; a shaft provided inside the main body so as to be rotatable relative to the main body facing in the vertical direction with one end protruding from the main body and fixed to a bearing on the building side; a pair of spring bearing members externally fitted on the shaft at intervals vertically; and a coil spring fitted externally on the shaft, located between the pair of spring bearing members, and having both upper and lower ends locked to the upper and lower spring bearing members, respectively. One spring receiving member of the pair of spring receiving members has a protrusion that comes into contact with a pressing part provided inside the main body and receives rotational force only when the main body rotates in one direction, and In order to stop the spring receiving member from rotating in the opposite direction, a protrusion that comes into contact with a stopper provided on the shaft is provided, and the other spring receiving member is provided inside the main body only when the main body rotates in the opposite direction. A hinge device comprising a protrusion that abuts a pressing portion and receives rotational force, and a protrusion that abuts a stopper provided on the shaft to stop the other spring receiving member from rotating in one direction.
