摘要： A working device is provided wherein a tilt bucket (70) is pivotally joined, vertically swingably, to the tip of an arm (33) by a third pivot joint pin (P3) and is vertically swung by a bucket cylinder (38) via first link members (81A, 81B) and a second link member (82). The connection unit (100) to be connected to the first link members (81A, 81B) is pivotally joined, vertically swingably, to the tip of the bucket cylinder (38). By switching the connection position of connection pins (131A, 131B) of the connection unit (100) and the first link members (81A, 81B) selectively between the position of a connection hole (H1) and the position of a connection hole (H2), the swing range and excavating force of the tilt bucket (70) are switched.
