摘要： A stroke amount detecting device includes a magnetism detecting unit, a first magnetic field generating unit and a second magnetic field generating unit. A magnetic pole of the first generating unit and a magnetic pole of the second generating unit, which are opposed to each other, have different polarities. A distance between a gap end of the first generating unit and a gap end of the second generating unit, which are located on a farther side of a rectilinear axis, is smaller than a distance between an open end of the first generating unit and an open end of the second generating unit, which are located on a closer side of the rectilinear axis. The magnetism detecting unit detects a stroke amount of an object based on a magnetic flux generated between the open end of the first generating unit and the open end of the second generating unit.

摘要： A position sensor includes a longitudinally extending permanent magnet member at least two longitudinally extending arc-shaped projecting elements respectively projecting from the opposite ends toward the inside space to confront each other at a distance and a pair of compatible main magnetic sensors disposed in the inside space along the longitudinal axis at an interval so as to generate a pair of output signals when the permanent magnet member shifts along the longitudinal axis. The opposite ends of the permanent magnet member are configured to surround a common inside space and polarized to have opposite magnetic poles so as to provide in the inside space a magnetic field whose magnetic flux density becomes a maximum at a longitudinal center of the inside space and gradually becomes smaller as a position of the inside space shifts from the longitudinal center along a longitudinal axis of the permanent magnet members. The arc-shaped projecting elements are arranged so that the magnetic flux density and each of the output signals can be expressed by a cosine of a shift value from the longitudinal center, and the interval is ¼ of the cycle of the cosine.

The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.
