To provide an anchor member with high durability of a caulking shaft part in comparison with a caulking shaft part of a conventional anchor member.

A caulking shaft part 10d of an anchor member 10 is plastically deformed into a taper shape in which a diameter of the caulking shaft part 10d becomes larger in proportion to being separated from a base end part 10a by an inner circumferential surface of a taper-shaped through-hole 56b. When force F and force F1 are input into an outer peripheral surface of a torque shaft part 10d of the anchor member 10 from brake shoes 22 and 24, pressing directions E, E1 of pressing the inner circumferential surface of the through-hole 56b by a taper part 10e in a side input with the force F and force F1 of the caulking shaft part 10d try to slant so as to approach a direction perpendicular to an axis C1 of the caulking shaft part 10d. Thicknesses T1, T2 of a portion in which stress of the caulking shaft part 10 is concentrated in the pressing directions E, E1 are extensively thickened than a thickness T of a caulking shaft part 100d of a conventional anchor member 100.
