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： A sensor case includes a body portion having a circular horizontal section. An upper body 1 includes an accommodation space 4 having a wall surface having a circular horizontal section, and the body portion is inserted in the accommodation space 4 such that the body portion is capable of rotating about a central axis thereof extending in a vertical direction. A stopper 50 is arranged to project in a horizontal direction in an outer circumferential surface of the body portion. A guide groove 51 is arranged to extend in the vertical direction at the wall surface of the accommodation space 4, and is arranged to allow the stopper 50 to move therein. The upper body 1 includes a restricting portion 52 arranged to restrict a vertical movement of the stopper 50.

摘要： According to one aspect of the present invention, there is provided an oil pressure sensor attachment structure including: the oil path body; the sensor case; and a fixing member which fixes the sensor case to the oil path body. The sensor case has a columnar portion which is disposed along a central axis extending in an up and down direction, and a flange portion which protrudes from the columnar portion to an outside in a radial direction. The fixing member has a fixing portion which comes into contact with the oil path body and is fixed thereto, and a pressing portion which comes into contact with the upper surface of the flange portion and presses the flanges portion against the oil path body. The fixing portion and the pressing portion are disposed with an interval therebetween.

摘要： An oil sensor attachment structure includes a guide projection disposed on an upper surface of an oil passage body and a sensor case. The guide projection includes a pair of first walls, a pair of first protrusions protruding toward each other, and a second wall. A receiving portion having a first receiving opening is provided between the first walls. The second wall faces the first receiving opening in a second direction with a gap therebetween. The sensor case includes a columnar portion, a flange protruding from the columnar portion, and a facing portion that is connected to the flange and that protrudes to a position above the flange. Each of the first protrusions has a first surface facing toward the other side in the second direction. The facing portion is disposed on the other side of the first surface in the second direction and faces the first surface.

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.
