A seal structure for a gas turbine blade including a shank including a first side surface, a second side surface, and a bottom surface located radially inward from a fin. The first side surface has a recess movably housing a wedge seal, and a slot on the bottom surface as an insertion opening for a spline seal. The second side surface has a slot on the bottom surface as the insertion opening. The recess has an inclined surface extending straight radially inward and away from the first side surface. The wedge seal includes a wedge portion including a first wedge surface to be opposed to the inclined surface and a second wedge surface to be opposed to the second side surface of the adjacent rotor blade to form a wedge together with the wedge surface, and a weight portion positioned radially inward in the recess from the wedge portion.
