Patent attributes
A rotation sensor includes a rotation detector mounted on a holder which is in turn inserted in a casing through its opening. A cover is formed by molding a resin so as to cover the opening of the casing and the portion of the holder protruding from the opening of the casing. A pair of relay terminals extend through a base portion of the holder and a gap defined in the holder, are fixed to a support wall, and connected to respective lead pieces of the detector. A resin cover is formed by molding a resin. When forming the cover, pressure is applied to the holder, thereby causing the holder to bulge axially in the holder. This in turn pushes the relay terminals in the axial direction. But since the relay terminals are fixed to the support wall, the support wall will absorb such pushing force, thereby preventing such pushing from being transmitted to the detector. In order to more effectively absorb such pushing force, the relay terminals may be provided with bent portions in the gap.
