PROBLEM TO BE SOLVED: To provide a quick coupler that automatically actuates and cancels a fall-off prevention function using a lock member, when an attachment is attached and detached.SOLUTION: An edge of a guide hole includes a first contacting part, a second contacting part and a guide part. The first contacting part comes into contact with a second connecting pin, while the second connecting pin is positioned at a lock actuation position. The second contacting part comes into contact with the second connecting pin while the second connecting pin is positioned at a lock releasing position. The guide part extends in a direction that intersects with a direction of shifting of the second connecting pin, between the first contacting part and the second contacting part. By being pressed by the second connecting pin that shifts from the lock actuation position to the lock releasing position, the guide part resists an energizing force of an energizing member and shifts a second lock member from a locked position to an unlocked position. |
