PROBLEM TO BE SOLVED: To provide a yaen capable of unconditionally overcoming the defect of a using range so as to solve the problems wherein a conventional yaen cannot be used when a squid gets on the yaen and requires to draw the squid to the point at 45°view by an angler to allow the squid to escape sometimes, and therefor the invention of the yaen solving the problems is required. SOLUTION: The self-propelled yaen is obtained as follows. A rod- or pipe-shaped float body 1 is formed, and yaens 2 are installed in the tip of the float body 1. A self-propelling power source 5 corresponding to the buoyancy is attached thereto. COPYRIGHT: (C)2007,JPO&INPIT
