Abstract: A portable apparatus component fixation structure which helps to secure the positioning accuracy for a second member (a mounted member) and which makes it possible to easily mount the second member is to be provided. A fixation structure is equipped with a fixation portion provided on a main plate and a regulating portion formed on a display plate. The fixation portion has a first pin and a second pin. The second pin has an inclined surface. The inclined surface is a surface generating a pressing force toward the regulating portion as the display plate approaches the main plate. Locking is effected in a state in which the regulating portion is held between the first pin and the second pin.
