Abstract: An artificial bait device or lure wherein a weight is longitudinally movably received in a main body thereof and a holding device for positively holding the weight at the central portion or forward portion of the main body is provided, whereby, when the lure is thrown, the weight is released by the holding device owing to the inertia thereof, so that the main body flies, with the weight shifted rearwardly toward the tail for holding the posture of the tail end thereof directed in the flying direction. When the lure lands on the water, the weight moves forwardly in the main body and is held by the holding device provided at the central portion or forward portion of the main body. The forwardly moved weight enhances the swimming action when the lure is drawn through the water.
