<p>PURPOSE:To simplify the structure of an unlocking device by having its unlocking operation of a door lock of a combine or the like performed so lightly by both outer and inner handles. CONSTITUTION:A handle arm 4 is attached to an outer handle 3 operable to open, against a spring 2, from the outside of a door 1. An unlocking arm 8 of a door lock 7 is interlocked by an inner handle 5 from the inside of the door 1 via a link rod 6. Those of handle arm 4 and unlocking arm 8 are pivoted around two shafts 9, 10 orthogonal with each other. In addition, an interval between these arms 4 and 8 is connected to be unlocked by a rod 13 whose one end is attached to the handle arm 4 and the other end is guided and engaged in a long hole 12 of the unlocking arm 8.</p> |
