To propose an idler wheel which can reduce a load exerted to a welding part by force being applied in an axle direction.SOLUTION: An idler 22 has: a first member 71; a first boss portion 81; a first rim portion 91; and a side plate 33. A second member 72 has: a second boss portion 82; a second rim portion 92; and a side plate 34. A third member 73 has a third shaft hole portion 831 into which an axle 27 is inserted and has a third boss portion 83 disposed between the first boss portion 81 and the second boss portion 82. A first welding part 61 is formed between the second boss portion 82 and the third boss portion 83 and connects the second boss portion 82 to the third boss portion 83. A second welding part 62 is formed between the first boss portion 81 and the third boss portion 83 and connects the first boss portion 81 to the third boss portion 83. A third welding part 63 is formed between the first rim portion 91 and the second rim portion 92 and connects the first rim portion 91 to the second rim portion 92.SELECTED DRAWING: Figure 3

    【課題】車軸方向の力に対して溶接部にかかる負荷を低減することが可能な遊動輪を提案すること。【解決手段】アイドラ22では、第1部材71は、第1ボス部分81と、第1リム部分91と、側板33と、を有する。第2部材72は、第2ボス部分82と、第2リム部分92と、側板34と、を有する。第3部材73は、車軸27が挿入される第3軸孔部分831を有し、第1ボス部分81と第2ボス部分82との間に配置される第3ボス部分83を有する。第1溶接部61は、第2ボス部分82と第3ボス部分83との間に形成され、第2ボス部分82と第3ボス部分83とを接続する。第2溶接部62は、第1ボス部分81と第3ボス部分83との間に形成され、第1ボス部分81と第3ボス部分83とを接続する。第3溶接部63は、第1リム部分91と第2リム部分92との間に形成され、第1リム部分91と第2リム部分92とを接続する。【選択図】図3
