A hinge device with improved durability for the direction of a rotary shaft is provided to reduce the frictional force occurring in the direction of a rotary shaft between a shaft and a rotation member effectively. The hinge device(20) with improved durability for the direction of a rotary shaft contains a main body(30) attached to a fixed object such as a wall(100), a rotation member(40) installed to be rotatable against the main body and fixed to a movable object such as a door(110), a shaft(50) placed on a rotary shaft of the rotation member and provided with a male thread, an insertion and a hexagonal wrench groove to connect the main body and the rotation member, and a thrust bearing placed in a housing of the rotation member, fitted to an insertion of the shaft and provided with a primary plate member, a secondary plate member, a support plate and balls to reduce frictional force occurring in the direction of a rotary shaft between the shaft and the rotation member. |
