Patent ID: 7859252

Claim:
A rotational angle detecting device comprising: a pair of permanent magnets attached to a rotary section and opposing to each other with respect to a rotational axis of the rotary section so as to produce a magnetic field therebetween; an angle sensor attached to a stationary section and positioned between the pair of permanent magnets, the angle sensor being constructed to determine a rotational angle of the rotary section based on change of the magnetic field caused by the rotation of the rotary section; and a connector provided on the stationary section and constructed to connect the angle sensor to an external device; wherein electrical connecting terminals are connected to the angle sensor and further connected to first ends of conductors each having a strength greater than each of the electrical connecting terminals; wherein the conductors have seconds ends opposite to the first ends and serving as connector terminals of the connector; wherein the rotational angle detecting device further comprises: a first resin-molded portion obtained by injecting a first resin into a first die, while at least the electrical connecting terminals, a part of the angle sensor and the first ends of the conductors are inserted into a first cavity of the first die; and a second resin-molded portion obtained by injecting a second resin into a second die, while portions of the conductors extending from the first resin-molded portion are inserted into a second cavity of the second die; wherein the stationary section comprises the first resin-molded portion and the second resin-molded portion; and wherein the connector is provided on the second resin-molded portion.
