Abstract:
A hinge assembly comprising a pair of abutment members arranged in mutually opposing relation and capable of making relative rotation, and bias means for biasing said pair of abutment members, so as to be press contacted with each other, one of said pair of abutment members having a projection formed on an opposing surface thereof and extending radially of said abutment member, the other abutment member having a recess formed on an opposing surface thereof and allowing said projection to be brought therein and out in accordance with the relative rotation of their said abutment members,said hinge assembly being characterized in that said recess comprises an inner recess at an inner side and an outer recess at an outer side in a radial direction of said abutment member, and one side surface of said inner press is parallel to a radial line of said abutment member and one side surface of said outer recess is slanted with respect to one side surface of said inner recess such that an inner end portion thereof is crossed with an outer end portion of one side surface of said inner recess and an outer end portion thereof is away from said inner recess in a circumferential direction towards an outside in the radial direction of said abutment member, so that the one side surfaces of said inner and outer recesses which contact one end portion of said projection, when viewed in a direction of axes of said abutment members, exhibit a substantially dogleg like configuration as a whole.
