Japanese Patent JP3699385
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a quick coupler device allowing a pair of pins provided on a work arm to be inserted into a bearing hole of a work device so as to come in and out freely and capable of realizing a twin holding structure of the pin and enlarging a bearing length of the pin.
SOLUTION: Each of a pair of device bearing holes provided in the work device is positioned between an inner bearing hole and an outer bearing hole provided in both end parts on an axial line extending in the direction of width of the work arm, respectively. A pair of pins come in and out of the outer bearing hole, the device bearing holes, and the inner bearing hole between an 'insertion position' and a 'pulling-out position' by a pin driving means from the outside in the direction of width of the work arm.
