To prevent a magnetic flux of a magnetic field from leaking to the surrounding area, wherein the magnetic flux of the magnetic field is emitted from a magnetic moving body, particularly, a magnet, and thereby, to prevent decrease in the quantity of a magnetic flux (magnetic flux density) of a magnetic field applied to a magnetism-sensing surface of a stroke sensor.
A waste gate valve control device includes a male-side connector housing 8 disposed in a projection part, which is perpendicular to a magnetism sensitive surface F of a Hall element of a stroke sensor S and is defined by projecting a region enclosed by the visible outline of a magnetic moving body 7 in a direction perpendicular to the region, wherein the male-side connector housing 8 prevents layout of an external magnetic body, an external magnet or the like that gives magnetic obstacles on the stroke sensor S. A magnetic circuit (comprising the magnetic moving body 7 and the stroke sensor S) is disposed within a range defined by projecting the region enclosed by the visible outline of the male-side connector housing 8 in a direction perpendicular to the region. Thereby, an external magnetic body, an external magnet or the like is prevented from being disposed around (near) the magnetic circuit.
