Patent ID: 8791692

Claim:
A magnetic position detecting device comprising: a magnet generating a magnetic field; first and second magnetoelectric conversion elements each provided on a first virtual plane and having a resistance value that changes in accordance with a change in said magnetic field caused by movement of a magnetic moving body; a detection circuit detecting movement of said magnetic moving body based on the change in the resistance value of each of said first and second magnetoelectric conversion elements; and a flux guide made of a magnetic material and disposed between said magnet and said first and second magnetoelectric conversion elements, said flux guide including first and second protrusions arranged spaced apart from each other in a first direction parallel to said first virtual plane, said first and second protrusions each protruding in a direction toward said first virtual plane, and a specific portion provided between and apart from said first protrusion and said second protrusion; said first magnetoelectric conversion element being provided closer to said specific portion as compared with said second magnetoelectric conversion element, said second magnetoelectric conversion element being provided between said first magnetoelectric conversion element and said first protrusion, as seen in a second direction perpendicular to said first virtual plane, and said specific portion being different in shape or material from the other portion of said flux guide except said specific portion between said first protrusion and said second protrusion such that, as compared to a case where said specific portion is not provided, there is a relatively great difference between a change in a component of a magnetic field parallel to said first virtual plane in a position of said first magnetoelectric conversion element and a change in the component of the magnetic field parallel to said first virtual plane in a position of said second magnetoelectric conversion element when said magnetic moving body moves.
