there are a plurality of connection portions toward the center of gravity of a polygon formed by connecting the connection portions or toward the central portion of the leg plate 14 the tensile force f and the torque m caused by the tensile force f which are described above tend to deform the connecting plate 16 in the present webbing take up device 10 the formation of the engraved portions 80 82 90 and 92 in the connecting portion 16 as described earlier inevitably lowers the overall rigidity of the connecting portion 16 relative to the case wherein the engraved portions 80 82 90 and 92 are not formed consequently the end portions 80 b and 90 b of the engraved portions 80 and 90 which are disposed at the connecting portion 16 transverse direction outer sides of the engraved portions 80 and 90 are located in a higher part of connecting portion 16 than the end portions 80 a and 90 a which are disposed at the connecting portion 16 transverse direction inner sides that is the longitudinal directions of the engraved portions 80 and 90 are along the directions in which the tensile force f acts on the connecting portion 16 further at the engraved portion 82 formed by the substantially rectangular holes 84 and 86 the end portion 84 a which is disposed.
