摘要	PURPOSE: To eliminate a need or a pivot screw by providing a spring loaded hinge with two hollow members which have bores and joint faces in end parts and previously applying a stress to the spring so that joint faces are pushed to each other with the intermediate part of connection parts between them. CONSTITUTION: A spring loaded hinge 11 has two hollow members 12 and 13 which have bores 17 and 18 respectively and have joint faces 12a and 13a in end parts. Two bores 17 and 18 are opened in orifices 17a and 18a faving each other, and the spring loaded hinge 11 has connection parts 15 which is stored in two bores 17 and 18 and pierces orifices 17a and 18a and has an expanded end part brought into contact with the inside end face of one bore and has the other end connected to a spring 16 stored in the other bore. A stress is previously applied to the spring 16 so that joint faces 12a and 13a are pushed to each other with the middle part of the connection parts between them. Thus, two members are held by each other with the springe loaded means, which has a high resistance in the transverse direction, without pivot screws neither a fear of damage.
