<p>PURPOSE:To obtain a biaxial type hinge having the stability of operation and excellent durability by conducting the revolution of an intermediate connecting plate to a fixing side blade and the revolution of a rotary side blade to the intermediate connecting plate in specified order. CONSTITUTION:The arcuate projecting edge surface section 10 of a fixing side blade 2 is engaged and disengaged with and from the arcuate recessed edge surface section 9 of a rotary side blade 4 in response to the places of the rotation of an intermediate connecting plate 7 to the fixing side blade 2 and the rotary side blade 4. The intermediate connecting plate 7 is constrained to the rotary side blade 4 or the fixing side blade 2 by engaging and disengaing the arcuate projecting edge surface section 8 of the rotary side blade 4 with and from the arcuate recessed edge surface section 11 of the fixing side blade 2.</p> |
