Claims

[Claim for Utility Model Registration] It is equipped with a winding drum for winding a wire with a weight attached to the tip, and a balance with a guide pulley attached to the tip to suspend the wire that is fed out from the winding drum. In a depth sounder that stops feeding out the wire by sensing the swing of the balance due to the decrease in tension applied to the wire when the weight reaches the measuring surface, a brake piece is installed opposite to the guide pulley, and the brake piece is attached to the wire. 1. A wire winding prevention device for a depth sounder, characterized in that a wire suspended on the guide pulley is held between a guide pulley and a wire that is moved by the swinging of the balance as the applied tension decreases.
