Claims

[Scope of Claim for Utility Model Registration] A boom that can swing vertically, a working tool that is pivotally supported on the tip of the boom so that it can swing vertically, a cylinder that swings the boom, and a cylinder that rotates the working tool. a cylinder for rotating the work implement, a control device for controlling these cylinders, and a detection means for detecting an angle formed between the work implement and the boom, and the control device operates the work implement rotation cylinder by detecting a predetermined angle by the detection means. In a work implement angle control device for a front loader configured to stop a front loader, the detection means includes a rod pivotally supported at a rear part of the work implement above a pivot point between the work implement and the boom, and the rod is arranged to stop the work implement and the boom. A detection member is provided on the rod and extends along the side surface and is adjustable in the axial direction;
The boom is rotatably provided with a support member that slidably supports the rod, and the support member is provided with sensing means for sensing the approach of the detection member, and the sensing means and the control device are connected to each other. A work implement angle control device for a front loader characterized by interlocking connection.
