Abstract
Disclosed is an attachment mounting/demounting device for working machinery by which a pin of an attachment held in engagement with an engagement groove of the mounting/demounting device can be surely locked and operation for locking and unlocking the pin can be easily performed. The mounting/demounting device comprises a latch capable of switching over between a release posture allowing a first pin to come into and out of a first engagement groove and an engagement posture preventing slip-off of the pin fitted to the engagement groove, a lock piston capable of switching over between a lock posture locking the latch in the engagement posture and an unlock posture releasing the latch from the lock posture, and a biasing spring for always biasing the lock piston toward the lock posture. Pressure oil is supplied to the lock piston for switching it over from the lock posture to the unlock posture in response to the pressure oil being supplied to a mounting/demounting cylinder for switching over the latch from the engagement posture to the release posture.
