A door panel of a side door of a machine has a latching mechanism, and a frame of the machine includes a striker. The striker includes a pair of vertically arranged mounting base portions, a pair of slanted shimmy-stopping surface portions formed on the mounting base portions so as to protrude in a V-like shape towards the latching mechanism, and a metal hooking portion protruding from a flat end portion that is provided between the slanted shimmy-stopping surface portions. The latching mechanism includes a mechanism body portion including main body plates. A U-shaped latch groove portion for engaging the metal hooking portion of the striker is formed by cutting away a part of each main body plate, and shimmy suppressing portions that are vertically arranged in a V-like shape are provided at the open end of each latch groove portion.

A second hinge plate supported pivotally on a first hinge plate using a shaft member so as to open and close. In the second hinge plate, a bracket is molded integrally at the upper edge of the end opposite the shaft member. A vertical shaft of a hold-stay rod is loosely fitted into a shaft hole of the bracket so as to move rotationally and slide in a vertical direction. A horizontal shaft of the hold-stay rod is inserted into a guide hole of a guide plate welded to the first hinge plate and slidable, and a stopper is folded and formed at the leading end of the hold-stay rod. The stopper is inserted into an engaging hole by movement from a guide to a receiving plate due to the opening movement of the second hinge plate and can be taken out from the engaging hole by a pushing-up operation.
