Claim 2:
3. The webbing take-up device of claim 2, wherein:
a first shaft portion and a second shaft portion are formed at substantially center portions of the respective first and second circular plates, the first and second shaft portions extending along the rotation axial direction from the respective first and second faces,
the first thrust teeth and the second thrust teeth extend toward the rotation radial direction outside,
one end portions of the first thrust teeth and the second thrust teeth in the rotation axial direction are thrust tooth base portions which are on the first and second respectively, and another end portions of the first trust teeth and the second thrust teeth in the rotation axial direction are thrust tooth tip portions, such that the first thrust teeth and the second thrust teeth protrude along the rotation axial direction from the thrust tooth base portions toward the thrust tooth tip portions,
the rotating member includes first radial teeth and second radial teeth formed to respectively a first outer circumferential face and a second outer circumferential face of the respective first and second shaft portions,
the first radial teeth and the second radial teeth extend along the rotation axial direction,
one end portions of the first radial teeth and the second radial teeth in the rotation radial direction are radial tooth base portions which are on the first and second outer circumferential respectively, and another end portions of the first radial teeth and the second radial teeth in the rotation radial direction are radial tooth tip portions, such that the first radial teeth and the second radial teeth protrude toward the rotation radial direction outside from the respective first and second outer circumferential faces.
