To reduce cases that differences occur in operation amounts of a lever due to differences in specifications.SOLUTION: A lever device 50 is adopted by a loaded type truck crane vehicle 10 equipped with an operation valve 42. The lever device 50 comprises a second lever 62, arranged at a left side of the loaded type truck crane vehicle 10, which slides a spool 85 of the operation valve 42, and a connection adaptor 86 that supports the second lever 62 turnably. The connection adaptor 86 forms a lever with a site thereof connected to the spool 85 (a front end part 80 of the spool 85) as a point of load, cooperatively with the second lever 62, which has support parts 93 and 94 that support the second lever 62 to constitute fulcrums. The support part 93 is laid out at a left side of the front end part 80. The support part 94 is laid out at a right side of the front end part 80. A distance L1 between the fulcrum constituted by the support part 94 and the front end part 80 is longer than a distance L2 between the fulcrum constituted by the support part 93 and the front end part 80.SELECTED DRAWING: Figure 6

    【課題】仕様の相違によるレバーの操作量に相違が生じることを低減する。【解決手段】レバー装置50は、操作バルブ42を備える積載型トラッククレーン車10に採用される。レバー装置50は、積載型トラッククレーン車10の左方に配置されて操作バルブ42のスプール85をスライドさせる第2レバー62と、第2レバー62を回動自在に支持する連結アダプタ86とを備える。連結アダプタ86は、第2レバー62と協働してスプール85との連結部位(スプール85の前端部80)を作用点とする梃子を形成し、第2レバー62を支持して支点を構成する支持部93、94を有する。支持部93は、前端部80の左方にレイアウトされている。支持部94は、前端部80の右方にレイアウトされている。支持部94が構成する支点と前端部80との距離L1は、支持部93が構成する支点と前端部80との距離L2よりも長い。【選択図】図6
