PROBLEM TO BE SOLVED: To provide a socket attachment structure of a marking torque wrench which has a simple structure and is easy for a user to check attachment conditions of a socket based on appearance. SOLUTION: A locking member 40 includes a lock pin 64 provided on a side face of an end of a socket body 30, protruding toward the socket body 30 and inserted into a lock hole 34, and an operating part 55 located oppositely to the lock pin 64 across the socket body 30. It is movable between a first position where the operating part 55 separates from a cover 33 of the socket body 30 and a second position where the operating part 55 comes closer to the cover 33 than the first position, and is urged to the first position by a coil spring 20. A tip 65 of the lock pin 64 enters an engagement recess 12 of a drive 11 in association with the movement to the first position and engages with the engagement recess 12. It disengages from the engagement recess 12 of the drive 11 in association with the movement to the second position and cancels the engagement with the engagement recess 12.
