<p>PURPOSE:To obtain a biaxial type hinge improved in the stability of operation and durability by conducting the rotation of an intermediate connecting plate to a fixing side blade and the rotation of a rotary side blade to the intermediate connecting plate in specified order by the interposition of a lock lever. CONSTITUTION:The arcuate projecting edge surface section 10 and long linear edge surface section 11 of the bearing arm section 4a of a rotary side blade 4 and the short linear edge surface section 12, arcuate projecting edge surface section 13 and long linear edge surface section 14 of the bearing arm section 2a of a fixing side blade 2 are engaged and disengaged with and from the long linear edge surface section 15, first short arcuate recessed edge surface section 16, first short linear edge surface section 17, second short arcuate recessed edge surface section 18 of a lock lever 9 in response to the places of the revolution of an intermediate connecting plate 7 and the rotary side blade 4 to the fixing side blade 2. Accordingly, the intermediate connecting plate 7 is constrained to the rotary side blade 4 or the fixing side blade 2.</p> |
