PROBLEM TO BE SOLVED: To provide a hydraulic unit mounted on a bucket, which can reduce the weight of an entire bucket, simplify the structure of the bucket, and achieve cost reduction.SOLUTION: A hydraulic unit mounted on a bucket comprises an electric motor 1 that can drive in forward and reverse directions, a gearbox 2 that has an input shaft 2a connected to the rotation shaft of the electric motor 1 and two output shafts 2b and 2c that selectively rotate according to the forward/reverse drive of the electric motor 1, and two hydraulic pumps 3a and 3b that are connected to the output shafts 2b and 2c, respectively, of the gearbox 2 to selectively discharge hydraulic fluid according to the forward/reverse drive of the electric motor 1, in which hydraulic fluid discharged from the hydraulic pumps 3a and 3b is supplied via a hydraulic fluid passage to a hydraulic cylinder 10 that performs bucket opening/closing operation.

    【課題】バケット全体の軽量化を図るとともに、バケットの構造を簡易化し、低コスト化できるバケット搭載用油圧ユニットを提供すること。【解決手段】バケットに搭載して使用される油圧ユニットであって、正逆転駆動可能な電動モータ1と、この電動モータ1の回転軸が接続される入力軸2a及び電動モータ1の正逆転駆動に合わせて選択的に回転する2つの出力軸2b、2cを有するギヤボックス2と、このギヤボックス2の出力軸2b、2cがそれぞれ接続され、電動モータ1の正逆転駆動に合わせて選択的に作動油を吐出するようにした2台の油圧ポンプ3a、3bとを備え、これらの油圧ポンプ3a、3bから吐出される作動油が作動油路を介してバケットの開閉操作を行う油圧シリンダ10に供給されるようにする。【選択図】図1
