Abstract: A joined body includes: a first member having a hole; and a second member that is press-fitted to the hole. The second member has a second abutment surface abutting against a first abutment surface which is an inner wall of the first member forming the hole. A groove portion is defined on one of an inner wall of the first member and an outer wall of the second member, and has a groove formed to extend in a press-fitting direction of the second member to the first member. An insertion portion is formed to protrude in a radial direction from the other of the inner wall of the first member and the outer wall of the second member, and is inserted in the groove. The groove portion has an engagement portion that is able to be engaged with an end portion of the insertion portion in the press-fitting direction.

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 sensor includes a detection unit. A resin portion covers the detection unit. A cover is formed of a resin having a linear expansion coefficient different from a linear expansion coefficient of the resin portion to cover a part of the resin portion such that the resin portion protrudes. The resin portion includes a protruding surface facing a direction in which the resin portion protrudes and a side surface connected to the protruding surface. The cover includes a covering surface facing the direction, an inclined surface intersecting with the covering surface and the side surface to be connected to the covering surface and the side surface, and a projecting portion projecting in the direction. The projecting portion is connected to each of the side surface and the inclined surface.

Abstract: A rotation angle sensor detects a rotation angle of a pedal by its first Hall IC and second Hall IC, which are disposed between two magnets and output voltages varying with magnetic flux changes. When the rotation angle of the pedal is an accelerator full-closure rotation angle or more, the first Hall IC generates a first voltage V1, which is twice as large as a second voltage V2 of the second Hall IC. When the rotation angle is less than 0°, the first Hall IC fixes the first voltage irrespective of the rotation angle. An ECU determines that the rotation angle is abnormal indicating that the pedal rotates in an accelerator closing direction beyond an accelerator full-closure position, when an output difference G1 calculated as G1=V1/2−V2 is more than a predetermined value.

Abstract: When a rotational angle of a pedal is in a range from an angle of zero degrees to a predetermined rotational angle, which is larger than a full-opening-time rotational angle, a first Hall IC outputs a first voltage, which is twice larger than a second voltage outputted from a second Hall IC. When the rotational angle of the pedal is larger than the predetermined angle, the first Hall IC outputs a predetermined constant voltage. When an output difference, which is computed based on the first voltage and the second voltage, is equal to or smaller than a second threshold value, an abnormality of the sensed rotational angle of the pedal is determined.
