PROBLEM TO BE SOLVED: To make a worker clearly remind to which drive state the worker should switch a hydraulic pump, and to prevent that a working machine performs an unexpected motion due to the improper changeover of the hydraulic pump to an engine drive state according to switch changeover operation by switch-controlling a power selection takeout mechanism to a blocked state in association with the changeover of a motor drive selecting switch to an off-position in a motor drive state, in accessories of the working vehicle in which the hydraulic pump can be selectively driven by an engine and an electric motor.SOLUTION: An engine drive state selecting switch P-SW and a motor drive state selecting switch M-SWf which can perform a switching operation to an on-position or an off-position are provided separately and independently. An accessory-side control device UK outputs a signal for switch-controlling a power selection takeout mechanism PS to a blocked state according to the changeover of a motor drive state selecting switch to the off-position in a motor drive state, and a signal for stopping an electric motor to a vehicle-side control device (UV).

    【課題】 作業車両の架装物において、油圧ポンプをエンジン及び電動モータで選択的に駆動可能とした上で、何れの駆動状態に切換えるかを作業員に明確に意識付けさせ得るようにし、併せて、モータ駆動状態でモータ駆動選択用スイッチがオフ位置に切換えられるのに関連付けて動力選択取出機構を遮断状態に切換制御することで、そのスイッチ切換操作に応じて油圧ポンプが不用意にエンジン駆動状態に切換わって作業機が予期せぬ動きをするのを防止する。【解決手段】オン位置又はオフ位置に各々切換操作可能なエンジン駆動状態選択用スイッチP−SW及びモータ駆動状態選択用スイッチM−SWfを別個独立に設け、架装物側制御装置UKが、モータ駆動状態でモータ駆動状態選択用スイッチがオフ位置に切換えられるのに応じて動力選択取出機構PSを遮断状態に切換制御する信号と、電動モータを停止させる信号とを車両側制御装置(UV)に対し出力する。【選択図】 図4
