Abstract: A position detection device includes a substrate disposed to face a displaceable detection object, a transmitting coil provided in the substrate, a first receiving coil and a second receiving coil which are disposed inside the transmitting coil in a normal direction with respect to a surface direction of the substrate, and a signal processing unit that derives a displacement amount of the detection object in view of a gap between the detection object and the substrate, based on a first characteristic value of the first receiving coil and a second characteristic value of the second receiving coil.

Abstract: A torque detection device includes a first yoke and a first magnetic guide member. A first opposing portion of the first magnetic guide member overlaps with a first-yoke ring of the first yoke when the first-yoke ring is projected onto the first opposing portion in an axial direction. Furthermore, the first opposing portion overlaps with an inner surface of a second tubular portion when the inner surface is projected onto the first opposing portion in the axial direction. A housing distance, which is a shortest distance measured from the first opposing portion to the inner surface, is longer than a yoke distance, which is a shortest distance measured from the first opposing portion to the first-yoke ring.

Abstract: A linear solenoid includes a collar, which limits relative movement between a first stationary core and a second stationary core. The first stationary core includes a bearing portion and a fixing portion, which are formed integrally as a single integral member. The bearing portion supports the shaft. The fixing portion is fixed to the yoke while the collar is clamped between the fixing portion and the second stationary core in the axial direction.

Abstract: A housing is molded from a resin material, and a first flange portion of the bobbin forms a fusing protrusion, which is joined and fused with the housing. The housing includes through-holes, which are located on a radially inner side of the fusing protrusion and extends through a portion of the housing in the axial direction. A yoke includes at least one pressure reducing part, which is configured to reduce a pressure exerted to a projection of the bobbin by a flow of the resin material at a time of molding the housing.

Abstract: One axial end of a through-hole of a bearing portion of a first stationary core located on a movable core side has a peripheral edge placed at a corresponding axial position. The corresponding axial position of the peripheral edge may be the same as an axial position of an axial end surface of a radially outer part of the first stationary core or is on an axial side of the axial end surface, which is axially opposite from the movable core. A bottom portion of a yoke may have a hole, which receives at least a part of a second stationary core. A stopper made of a resin material may be placed on a side of the bottom portion of the yoke, which is opposite from the second stationary core in the axial direction. A shaft may be abuttable against the stopper.
