To provide an adapter for a case lock, and a case lock which are compatible with a locking/unlocking shaft having a square, cross-shaped or rectangular cross section, while eliminating the risk of idling upon rotation of the locking/unlocking shaft.
The adapter having a tube shape fitted into a fitting hole formed in a lock cam of the case lock provided with the lock cam for locking and unlocking by rotation includes an insertion hole formed by a square hole and rectangular holes overlapping with each other. Each of the rectangular holes includes a diagonal line of the square hole as the center line, projects outward from each corner of the square, and has a locking/unlocking shaft abutting face height l1. A projection which forms a rectangular hole, having a locking/unlocking shaft abutting face height l2 larger than the locking/unlocking shaft abutting face height l1, is formed on an inner wall of a deep side of the insertion hole. A downward slope surface toward the opening is formed on each of both opening sides of the projection. A tube body having the projection formed is deflected in the direction perpendicular to the direction of the insertion when the locking/unlocking shaft having the square cross section is inserted.
