1. A fishing lure having appearance analogous to a small fish and comprising a hollow lure body which is provided with a forwardly slanting lip on one end, in which the hollow lure body contains therein a center-of-gravity movable tube comprising a longitudinally straight tube body which is straight from the front end to the last end of the tube body and a weight body in the form of a stick which is capable of moving in the tube body in the longitudinal direction, in which:
the center-of-gravity movable tube is installed in the lure body in the position lower than the middle height of the hollow space of the lure, and the weight body has a vertical section which is symmetrical in the width direction of the weight body and in the form of trapezoid having a width larger on a top than a width on a bottom side, and having two side surfaces which are not parallel to each other,
the weight body has a pair of ball circulation grooves, each ball circulation groove being composed of two grooves connected to each other forming an oval shaped path, and being filled up with balls such that the balls rotate and circulate within each ball circulation groove,
wherein, one of the two grooves of each ball circulation groove is formed on and along one of the two side surfaces of the weight body, and the other of the two grooves is formed at and along a lower corner of the weight body where the one of the two side surfaces intersects with a bottom surface at the bottom side of the weight body,
the weight body does not have more than the pair of the ball circulation grooves, and
when the weight body moves in the tube body in the longitudinal direction, the balls rotate and circulate within each ball circulation groove while the balls in the other of the two grooves are to be in contact with an inner surface of the tube body along the lower corner of the tube body.
