A movable hood for a reel seat has a hood portion, through which a body of a reel seat passes, and a nut portion, which is connected to the hood portion to rotate around the body and is threadedly coupled to an outer peripheral surface of the body at an inner peripheral surface. The hood portion has a pair of first guide projections and a second guide projection which are fitted to the outer peripheral surface of the body. The first guide projections project from an inner peripheral surface of the hood portion above a central axis of the hood portion, and the second guide projection projects from the inner peripheral surface of the hood portion at a lower end of the hood portion. A radial thickness in a cross section of the hood portion gradually decreases from the first guide projections toward the second guide projection.
