Abstract: A magnetostrictive torque sensor for detecting a torque applied to a magnetostrictive member having magnetostrictive properties, includes a detection coil arranged on an outer peripheral side of the magnetostrictive member; a magnetic ring composed of a ferromagnetic material arranged on an outer peripheral side of the detection coil; a housing having a facing portion facing the magnetic ring across the detection coil; a plug member closing an opening formed between the magnetic ring and the facing portion; a resin mold section covering the housing while exposing the magnetic ring and the plug member; a cable electrically connected to the detection coil and drawn out from the housing and the resin mold section; and a heat shrinkable tube covering the housing, a portion of the resin mold section, and an end portion of the cable exposed from the housing and the resin mold section.

Abstract: A magnetostrictive torque sensor, configured to be mounted around a rotating shaft having a magnetostrictive effect and to detect torque applied to the rotating shaft, is provided with a support member having a cylindrical portion through which the rotating shaft is inserted; a flexible substrate arranged around an outer periphery of the cylindrical portion and having a plurality of coils composed of wiring patterns; and a tightening member that tightens the flexible substrate toward an outer peripheral surface of the cylindrical portion. The tightening member may be a tubular heat-shrinkable tube that shrinks upon heating.

Abstract: A resin-sealed electronic component includes an electronic component main body sealed with a resin housing. The resin housing includes a pair of resin members aligned in a first direction with sandwiching a housing space housing the electronic component main body, and a sealing member including a molding resin and being molded so as to cover at least a portion of each of the pair of resin members. A portion of one resin member of the pair of resin members and a portion of the other resin member are aligned in a second direction intersecting the first direction to constitute a suppression structure that suppresses the molding resin from entering the housing space.

Abstract: A harness member includes a cable, a housing with an insertion hole through which the cable is inserted, a heat-shrink tubing covering the housing and the cable exposed on one side from the insertion hole, and a hot melt adhesive to seal between the heat-shrink tubing and the cable and between the heat-shrink tubing and the housing. A recess is formed on the housing so as to be recessed from an outer circumferential surface covered with the heat-shrink tubing. At least a portion of the hot melt adhesive melted between the outer circumferential surface of the housing and an inner circumferential surface of the heat-shrink tubing has flowed into the recess.

Abstract: A magnetostrictive torque sensor includes detection coils formed around a magnetostrictive material made of chrome steel or chrome molybdenum steel, a magnetic ring configured to cover around the detection coils, and a drive unit for providing alternating current excitation to the detection coils at an excitation frequency of 50 kHz or more and 333 kHz or less. A torque applied to the magnetostrictive material is detected based on a change in inductance of the detection coils. The magnetic ring is configured by wrapping around the detection coils with an amorphous tape made of amorphous soft magnetic material in a tape shape. The thickness of the magnetic ring is 1.455 times or more as thick as a skin effect thickness of the magnetostrictive material and less than 1.000 mm.

Abstract: The torque measuring device includes: a casing made of a magnetic metal; a rotating shaft rotatably arranged inside the casing and having a magnetostrictive effect section whose magnetic permeability changes according to torque to be transmitted; and a torque sensor arranged around the magnetostrictive effect section and supported by the casing, the torque sensor including a coil unit formed in a cylindrical shape using a flexible substrate having a detection coil that changes voltage in response to changes in the magnetic permeability of the magnetostrictive effect section, and a holder made of rubber or synthetic resin, covering an outer peripheral surface of the coil unit, and having a portion that protrudes from the coil unit on both sides in an axial direction; and the torque sensor supported by the casing with an outer peripheral surface of the holder fitted into an inner peripheral surface of the casing.
