Abstract
A gear position detecting apparatus includes three magnets fixed to a transmission housing for generating magnetism and three hole elements fixed to the transmission housing for detecting magnetism generated from the magnets. A magnetism shielding plate is provided between the magnets and the hall elements. The magnetism shielding plate is slidably and rotatably movable according to a shift pattern of a shift lever and has a plurality of holes and a cut-out portion. The magnetism generated from the magnets is permitted or forbidden to pass through these holes or the cut-out portion according to the movement of the magnetism shielding plate which is moved by the shift lever. The hall elements output an ON-signal when the magnetism is permitted to pass through and an OFF-signal when the magnetism is forbidden to pass through. As a result, a plurality of combinations of binary signals are produced corresponding to gear positions.
