To provide a handrail provided to a body of a working machine, the handrail comprising a handrail body that is easily mounted, and preventing rattling of the handrail body after it is mounted.SOLUTION: A handrail has a handrail body and a pair of frame coupling parts 210. A pair of handrail coupling parts 55 of the handrail body each has a pair of front and back handrail side-tabular parts 550, an engagement pin 551, and a first hole part. The pair of frame coupling parts 210 each has a frame side-tabular part 210A, an engagement concave part 211, and a second hole part 212. Even when an outer diameter of the engagement pin 551 varies within tolerance, an outer periphery of the engagement pin 551 stably abuts on an inclined surface 211A by dead weight of the handrail body, preventing rattling of the handrail body. Moreover, a coupling pin 60 is easily mounted on the first hole part and the second hole part 212 which is formed into a long-hole shape, each of the first hole part and the second hole part 212 being opened in the pair of handrail side-tabular parts 550.SELECTED DRAWING: Figure 6
【課題】手すり本体の装着が容易であるとともに装着後の手すり本体のガタツキを抑制した、作業機械の機体に備えられる手すりを提供する。【解決手段】手すりは、手すり本体と、一対のフレーム連結部210と、を有する。手すり本体の一対の手すり連結部55は、前後一対の手すり側板状部550と、係合ピン551と、第1孔部と、をそれぞれ有する。一対のフレーム連結部210は、フレーム側板状部210Aと、係合凹部211と、第2孔部212と、をそれぞれ有する。係合ピン551の外径が公差内でばらついても、手すり本体の自重によって係合ピン551の外周面が傾斜面211Aに安定して当接し、手すり本体のガタツキが抑制される。また、一対の手すり側板状部550にそれぞれ開口された第1孔部および長穴状の第2孔部212に、連結ピン60が容易に装着される。【選択図】図6
