Claim:
An attachment member for attaching a predetermined strap to an external surface of a musical instrument, including a shaft-shaped member that is inserted inside a hole formed in the external surface of the musical instrument and is fixed inside the hole via an adhesive agent; and a holding member for holding the strap that is continuous with the shaft-shaped member and is positioned on an exterior side of the hole, said shaft-shaped member comprising: a first shaft-shaped portion that is positioned on a distal end side of the shaft-shaped member and is placed in contact with an inner circumferential surface of the hole; a second shaft-shaped portion that is positioned on a base portion side of the shaft-shaped member and that forms a space between itself and the inner circumferential surface of the hole where the adhesive agent is contained; and a dividing groove that is formed in said first and second shaft-shaped portions, wherein when the shaft-shaped member is inserted into the hole, the first shaft-shaped portion is deformable in conformity with an internal surface configuration of the hole while narrowing a groove width of the dividing groove, wherein said first shaft-shaped portion has an area that is formed in a substantially circular column shape or a substantially circular cylinder shape, while said second shaft-shaped portion is formed in a tapered shape whose diameter gradually narrows as it approaches the first shaft-shaped portion, and wherein a maximum diameter of the second shaft-shaped portion is set substantially equal to or slightly smaller than a diameter of the first shaft-shaped portion.
