Abstract:
1. A rotation sensor comprising a casing having an opening at one end thereof, a holder having a base portion and inserted in said casing with said base portion fitted in said opening of said casing, a detector mounted on said holder and received in said casing for sensing any change in a magnetic field produced when a rotary member rotates and converting such change in the magnetic field to electrical signals, a pair of relay terminals having protruding ends protruding from an outer end face of said base portion of said holder, an output line connected to said protruding ends of said relay terminals, a cover formed of a resin and covering said opening of said casing, a portion of said holder protruding outwardly from said opening of said casing, said protruding ends of said relay terminals, and a portion of said output line connected to said protruding ends of said relay terminals, said holder being formed of a resin and defining a gap, and a support wall fixed to said holder, said detector comprising a sensor element for sensing any change in the magnetic field produced from the rotary member, and a pair of lead pieces extending from said sensor element in parallel to each other, said relay terminals extending through said base portion of said holder and said gap, being fixed to said support wall, and each being directly connected to one of said lead pieces, and said gap being so formed as to provide a clearance around said relay terminals.
