Abstract
A torque detection device includes: a magnetic flux collecting unit, and a sensor housing. The magnetic flux collecting unit includes a holder, first and second magnetic flux collecting rings, and a magnetic shield. The holder has upper and lower through-holes. The first and second magnetic flux collecting rings are fitted to an inner periphery of the holder. The magnetic shield is fitted to an outer periphery of the holder so as to cover the through-holes. The sensor housing is formed integrally with the magnetic flux collecting unit by supplying resin onto an outer periphery of the magnetic flux collecting unit. The holder has a resin flow passage in its outer periphery. Resin that is supplied at the time of forming the sensor housing flows into the through-holes through the resin flow passage.
