Abstract:
1. A tilt hinge for connecting a first member and a second member which are opened and closed with respect to each other in a manner to be friction-rotatable, said hinge comprising: a holder composed of an attachment portion, a case portion having a cavity portion with a locking groove mounted on said attachment portion, and a sidewall with a bearing hole mounted on one side of said cavity portion, said bearing hole having the same axis with said cavity portion, and attached to either one of said first member or said second member; a shaft composed of a deformed small-diameter portion, a flange portion and an attachment portion, which shaft is rotatably mounted on said bearing hole with its small diameter portion penetrating in an axial direction of said cavity portion, and said attachment portion of said shaft being attached to either the other one of the first member or the second member; a plurality of first friction disks with locking portions, said first friction disks being engaged on the small-diameter portion of said shaft in an axial direction by a circular through-hole of each one of said first friction disks, and said first friction disks being held in said cavity portion of said holder, and said locking portions being engaged with said locking groove; a plurality of second friction disks having deformed through-holes in the central axial direction, the shaft extending through said deformed through-holes of each one of said second friction disks, and thus connecting with said deformed through-holes, and being interposed between said first friction disks, and held in the cavity portion of said holder rotatable along with said shaft; an elastic means provided on said shaft for press-contacting with each other the first friction disks and the second friction disks; and fastening means attached on an end of said small diameter portion of said shaft in order to create elasticity in said elastic means.
