PROBLEM TO BE SOLVED: To enhance workability when an arm, a working implement and a working implement cylinder, which constitute a working device, are connected together via a link device. SOLUTION: A one-side arm link 15 constituting an arm link 14 is split into two links, that is, the first split link 16 to which a cylinder connecting pin 20 is to be fixed, and the second split link 17 to which an arm connecting pin 21 is to be fixed. Thus, the operation of inserting the arm connecting pin 21 through a link connecting boss 6B of the arm 6, and the operation of inserting the cylinder connecting pin 20 through a one end-side boss 12A of a working implement-side link 12 and the rod end boss 10C of the working implement cylinder 10 can be independently performed; shortening a working time in the insertion of the arm connecting pin 21 and the cylinder connecting pin 20. Then, the workability can be enhanced when the arm 6, a bucket 7 and the working implement cylinder 10 are connected together by means of the link device 11. COPYRIGHT: (C)2011,JPO&INPIT
