PURPOSE: A lock handle apparatus for rotary type door is provided to achieve prevention against corrosion at an outer surface of the handle and damage at a connecting axis portion of the handle CONSTITUTION: An apparatus an axis support cylinder portion(3) protruded at a rear surface of a fixing case(2), a primary axis(4) inserted into the portion(3), a secondary axis(5) inserted with the primary axis(4), an operation handle(8) having an end pivot-attached to the front end of the axis(5) by a pivot axis(9), a distance(D1) between a side surface of the handle(8) and the pivot axis(9) being arranged longer than a distance(D2) between an end(8b) of the handle(8) and the pivot axis(9), a restricting disk(10) inserted into an end of the axis(5), a spring(11) inserted between an inner bottom of the cylinder portion(3) and the disk(10), a plurality of protrusions(13), a plurality of stopper protrusions(14), and a detent(17) arranged at a rear end of the axis(5). When the handle(8) is laid down toward a recess portion(7) of the case(2), the handle(8) gets caught by the protrusions(13, 14) so that the handle(8) can be placed at a normal position in the recess(7).
