摘要： Provided is a strap pin fitting allowing easy attachment and detachment of a strap with respect to a musical instrument. A strap pin fitting includes: a base plate; a strap retaining portion arranged on the base plate and configured to retain a strap; a through-hole formed in the base plate and allowing insertion of a strap pin; and a presser plate attached to the base plate. The presser plate is movable between an open position where the through-hole is opened and where the operation of inserting the strap pin into the through-hole is allowed and a closed position where a part of the through-hole is closed and where detachment of the strap pin from the through-hole is prevented.
