PROBLEM TO BE SOLVED: To provide a working-machine connecting device for improving the reliability of the connection between connecting terminals in a working-machine connecting device, in which the paired connecting terminals on a connection frame side terminal and the paired connection terminals on a working machine side are connected when the working machine is automatically connected to a connection frame disposed at a tractor back portion.SOLUTION: Paired connection terminals are disposed on the side of a tractor body side and a working machine side, and a pair of fitting recesses and a pair of protruding portions are provided to fit each other when a working machine is connected to a connection frame. The paired fitting recesses are juxtaposed in the transverse direction, and the paired protruding portions are juxtaposed in the transverse direction. One of the paired connection terminals is disposed in one of the transverse fitting recesses, and the other of the paired connection terminals is disposed in the other of the transverse fitting recesses. One of the connection terminal in the connection terminals of the other pair is disposed at one of the transverse protruding portion. The other connection terminals in the other paired connection terminals are disposed at the other protruding portion. The working machine side connector having the paired connection terminal on the working machine side is supported in a vertically rocking manner on the working machine.COPYRIGHT: (C)2014,JPO&INPIT【課題】トラクタ後部に設けた連結枠に作業機が自動連結される際に連結枠側の対の接続端子と作業機側の対の接続端子とが接続される作業機連結装置において、接続端子同士の接続の信頼性の向上を図る。【解決手段】トラクタ車体側の対の接続端子と作業機側の対の接続端子とを設け、作業機が連結枠に連結される際に互いに嵌合する嵌入凹部と突出部とをそれぞれ一対設け、一対の嵌入凹部を左右方向で並べて配置すると共に一対の突出部を左右方向で並べて配置し、左右の嵌入凹部の内の一方の嵌入凹部内に一方の対の接続端子の内の一の接続端子を設けると共に他方の嵌入凹部内に該一方の対の接続端子の内の他の接続端子を設け、左右の突出部の内の一方の突出部に他方の対の接続端子の内の一の接続端子を設けると共に他方の突出部に該他方の対の接続端子の内の他の接続端子を設け、作業機側の対の接続端子を備えた作業機側コネクタを上下揺動可能に作業機に支持する。【選択図】図1
