PROBLEM TO BE SOLVED: To provide a new attachment-installing mechanism which can be engaged with two kinds of attachments, both old and new. SOLUTION: The attachment-installing mechanism is provided with a pair of right-and-left joining plates 32, a pair of right-and-left supporting plates 33, an engagement bar 36, a pair of right-and-left snap hitches 6, and an anti-disconnection pin 20. The pair of right-and-left joining plates are attached to the tip of a pair of right-and-left lift arms 12 with flexible rotation, and are elevated by a dumping cylinder 9 through the medium of a four-joint linkage 8. Then the pair of right-and-left supporting plates are attached integrally with the joining plates 32 in the inside positions of the joining plates, and the engagement bar connects the upper end parts of the supporting plates 33 to each other. Then the snap hitches are attached to the outside positions of the joining plates 32 with flexible removability, and the engagement part position at the tip of the snap hitch 6 is in agreement with the position of the engagement bar 36. Then the anti-disconnection pin can be extruded and recessed from the pair of right-and-left supporting plates 33 in the right-and-left direction. COPYRIGHT: (C)2006,JPO&NCIPI
