PROBLEM TO BE SOLVED: To provide an apparatus for connecting a universal joint to the output shaft of a tractor, which is able to surely perform a simple and reliable connection and has a simple structure.SOLUTION: The apparatus is equipped with a first connection means 48 which is installed incapable of turning to the universal joint, and a second connection means 17 installed incapable of rotating to the output shaft 1 of the tractor and being incapable of turnably connected to the first connection means for transmitting torque. The first connection means is moved to a predetermined connecting position and connected to the second connection means, by installing a connection shield 7 for supporting the first connection means, at least to be indirectly turnable to connect the connection means and having a locking means, installing a bracket having at least one locking device which is attachable in the posterior portion of the tractor and being displaceable between an unlocked position and a locked position, and carrying out the displacement of the locking device form the unlocked position to the locked position, as well as, making the locking device to mutually act on the locking device, with the locking means, to pull the connection shield toward the bracket.COPYRIGHT: (C)2009,JPO&INPIT【課題】簡単で信頼できる結合を確実に行い構造が簡単な、牽引車の動力出力軸に自在継手軸を結合する装置。【解決手段】自在継手軸に回動不能に配置された第1の結合手段48と、牽引車の動力出力軸1上に回動不能に配置されてトルク伝達のため第1の結合手段に回動不能に結合可能な第2の結合手段17とを備える。結合手段を結合させるために第1の結合手段を少なくとも間接的に回動可能に支持すると共にロック手段を有する結合シールド7が配設され、牽引車の後部に取付け可能であると共にロック解除位置とロック位置との間で変位可能な少なくとも一つのロック装置を有するブラケットが配設され、ロック装置をロック解除位置からロック位置へ変位させると共にロック装置にロック手段を相互作用させることで、結合シールドをブラケットに向け引張り、第1の結合手段を所定の結合位置へ移動させて第2の結合手段と結合させる。【選択図】図6
