PROBLEM TO BE SOLVED: To solve the problem that, with a conventional technology, a work machine cannot be attached because of incapability of coping with a standard of different lower pin width although capable of coping with a standard of different top pin height.SOLUTION: A work machine intermediate connection device includes a work machine connection device(11) in which a work vehicle (1) is attached in the front part and a work machine intermediate connection device (12) for connection of a work machine (R) at a rear part. The work machine intermediate connection device (12) includes a top pin (13) at an upper part in front of it, and lower pins (14),(14) on the left and right at a front lower part. A top hook (16) which hooks a pin (15) of the upper part of the work machine is provided at the upper part behind it, and pin receiving parts (18),(18) for engagement with a pin (17) at the lower part of the work machine are provided at the left and the right side of the rear lower part. A triangular shape formed by connecting the top pin (13) with the lower pin (14) by a straight line has a different shape or a different size.SELECTED DRAWING: Figure 5 【課題】本発明は、従来の技術では、トップピンの高さが異なる規格には対応できるものの、ロワピン幅が異なる規格には対応することができず、作業機を装着することができという課題があった。【解決手段】本発明は、前方に作業車両（１）に装着された作業機連結装置（１１）と、後方に作業機（Ｒ）を連結する作業機中間連結装置（１２）を備え、作業機中間連結装置（１２）には、前方の上部にトップピン（１３）、前方下部の左右にロワピン（１４），（１４）を備え、後方の上部に作業機上部のピン（１５）を掛止するトップフック（１６）、後方下部の左右に作業機下部のピン（１７）を嵌合するピン受け部（１８），（１８）を備え、前記トップピン（１３）と前記ロワピン（１４）とを直線で結んだ三角形状とが異なる形状又は異なる大きさである構成とする。【選択図】 図５
