<p>In order to reduce the number of parts and facilitate the layout of the components, a latching device is integrally provided with shimmy stopping members that serve to prevent vibration of a door panel. A door panel of a side door of a hydraulic excavator is provided with a latching mechanism 43, and a frame provided at the machine body includes a striker 44. The striker 44 includes a pair of vertically arranged mounting base portions 45, a pair of slanted shimmy-stopping surface portions 46 formed on the mounting base portions 45 so as to protrude in a V-like shape towards the latching mechanism 43, and a metal hooking portion 48 protruding from a flat end portion 47 that is provided between the slanted shimmy-stopping surface portions 46. The latching mechanism 43 includes a mechanism body portion 52 including main body plates 52a,52b. A U-shaped latch groove portion 55 for engaging the metal hooking portion 48 of the striker 44 is formed by cutting away a part of each main body plate 52a,52b, and shimmy suppressing portions 56 that are vertically arranged in a V-like shape are provided at the open end of each latch groove portion 55.</p> |
