PURPOSE:To make disassembling, internal inspection and repair easy by approaching the bottom surface of a sliding plate fitting to the bottom surface of a spring case by means of a screw mechanism, thereby compressing springs and releasing the interface press-contacting force between the under surface of a stationary plate brick and the top surface of a sliding plate brick. CONSTITUTION:This is the sliding opening-closing device which press-contacts the top surface of a sliding plate brick 3 to the under surface of a stationary plate brick 2 by the force of springs 17 wherein the sliding plate fitting 18 containing the brick 3 and the spring case 14 containing the springs 17 are approached by screwing bolts, whereby the springs 17 are compressed. Thereby, the interface press-contacting force between the brick 2 and the brick 3 is released. Hence, the load of a pin 15 is only the own-weight of the part riding thereon and this facilitates removing the pin 15 and disengaging the detention between the pawl 16 and pawl hook 12 of a hinge. |
