ABSTRACT:
A position detecting device has a movable unit, and a hold unit that movably holds the movable unit. One of the movable unit and the hold unit has a magnetic field generator having an engaged portion and a guide opening. A magnetic field sensor is provided on the other unit of the movable unit and hold unit. The sensor senses the magnetic field so as to detect the position of the movable unit relative to the hold unit. The magnetic field generator is fixed to the first surface after the magnetic field generator is slidingly moved by a rod member inserted into the guide opening and engaged with the engaged portion so as to dispose the magnetic field generator at a predetermined position.
