摘要： An aspect of the disclosure provides a rotation angle detecting device capable of detecting a rotation angle of a rotation body rotatable about a central axis. The rotation angle detecting device includes: a sensor magnet, having multiple magnetic poles provided side-by side in a circumferential direction about the central axis and installed to the rotation body; a magnetic sensor, overlapped with the sensor magnet when viewed in a predetermined first direction and capable of detecting a magnetic field of the sensor magnet; and a pair of magnetic parts, provided to sandwich the magnetic sensor in a second direction intersecting the first direction.

摘要： The sensor unit (40) includes a case (41) having a bottom surface (41a); a sensor element (42) including a sensor element main body (421) and a power supply terminal (42a); and a power supply bus bar (44) including an inclined part (44d). An end on one side of the power supply terminal (42a) is electrically connected to the sensor element main body (421). The case (41) further includes a terminal passage part (412a). In a state where the power supply terminal (42a) passes through the terminal passage part (412a), an end on the other side of the power supply terminal (42a) is in contact with the inclined part (44d) and the terminal passage part (412a) is in contact with a side surface of the power supply terminal (42a), so that movement of the power supply terminal (42a) in a direction away from the bottom surface (41a) is restricted.

摘要： A guide protrusion includes first walls protruding upwards from an upper face of a body, facing each other across an opening in a first direction, and first protrusions protruding from each first wall toward the other. A receptive portion between the first walls has a first opening, opening to one side in a second direction orthogonal to the first direction. The sensor case is received from the first opening following the second direction. The guide protrusion has a first movement restricting face facing another side in the second direction. The sensor case includes a columnar portion extending vertically through a gap between the first protrusions, a flange at least partially between the upper face and the first protrusions in the vertical direction, within the receptive portion, and a facing portion on the other side of the first movement restricting face in the second direction, facing the first movement restricting face.

摘要： An electric actuator is provided. The electric actuator includes a motor, a deceleration mechanism, case, an output part, a first rotation sensor and a holding member that holds the first rotation sensor in the case. The case includes a first recess that is recessed from an inner surface of the case to one side in a first direction and a support surface that faces the other side in the first direction. The first rotation sensor includes a sensor main body which includes a sensor chip and is accommodated in the first recess and a projection that protrudes in a second direction orthogonal to the first direction from the sensor main body. The projection is supported on the support surface from one side in the first direction. The sensor main body is disposed on the other side in the first direction away from the bottom surface of the first recess.

摘要： Each of a plurality of hydraulic pressure sensors includes a lower case and an upper case fixed above the lower case. A valve body includes an upper body including a hole portion arranged to house the hydraulic pressure sensors, and a lower body including an oil passage. A pressed portion is defined in the lower case. The pressed portion is arranged to project horizontally in the lower case so as to be opposed to the upper case. The pressed portion is arranged to be pressed downward by a pressing portion of the upper body. At least one of the upper body and the lower body includes a positioning portion arranged to horizontally position each of the hydraulic pressure sensors in the hole portion.

摘要： An oil pressure sensor attachment structure includes the oil path body; the sensor case; and a seal member. The oil path body has an accommodation hole portion which accommodates the oil pressure sensor. The accommodation hole portion has a small-diameter hole portion and a large-diameter hole portion. The sensor case has a columnar portion which is disposed along a central axis extending in the up and down direction and of which at least a portion is inserted into the small-diameter hole portion. A flange portion which protrudes from the columnar portion to an outside in a radial direction and is inserted into the large-diameter hole portion. The flange portion is disposed to face a lower side of the upper body in the up and down direction. The seal member has an annular shape, and seals a portion between an inner surface of the accommodation hole portion and the sensor case.
