Abstract

To suppress damage to a magnet in a mounting structure using the magnet.SOLUTION: A mounting structure 20 includes a main body 30 and a handwriting changing tool 80 that changes handwriting. One of the main body 30 and the handwriting changing tool 80 has a magnetic member 87. The other of the main body 30 and the handwriting changing tool 80 has a magnet 50 facing the magnetic member 87 in an axial direction da, and a protective member 60 that prevents the magnet 50 and the magnetic member 87 from coming into direct contact. The handwriting changing tool 80 is detachably attached to the main body 30 by the magnetic force of the magnet 50.SELECTED DRAWING: Figure 2
