To provide an outrigger device in which an oil feed hose can be stretched and turned back in the middle, even in a work vehicle on which a slide cylinder is arranged.SOLUTION: In an outrigger device, an oil feed hose 20 is directed to a base end of an inner box along the other side corner part of an upper part of an outer box in a space between a top plate of the outer box and a top plate of the inner box from an outer box-side hydraulic joint. The oil feed hose is folded in a U-shape, enters the inner box from an opening part of the base end of the inner box, and is directed to a tip end of the inner box along a one-side corner part of a lower part of the inner box on a diagonal line with respect to the other side corner part of the upper part of the outer box such that the oil feed hose is connected to a jack cylinder side hydraulic joint. A slide cylinder 25 is arranged on an inner corner part of the inner box 11 on another diagonal line intersecting with the diagonal line along which the oil feed hose 20 is routed.SELECTED DRAWING: Figure 8
【課題】 スライドシリンダが配置される作業車においても、送油ホースをタスキ掛けにすることができるアウトリガ装置を提供する。【解決手段】 送油ホース20が外箱側油圧ジョイントから外箱上板と内箱上板との間の空間内を外箱の上部他側コーナー部に沿って内箱基端に向かい、U字形状に折り曲げられて内箱基端の開口部から内箱内に入り前記外箱の上部他側コーナー部とは対角線上となる内箱の下部一側コーナー部に沿って内箱先端に向かい、ジャッキシリンダ側油圧ジョイントに接続されるアウトリガ装置において、前記スライドシリンダ25を、前記送油ホース20が配索される対角線と交差するもう1本の対角線上となる前記内箱11内部コーナー部に配置する。【選択図】 図8
