Oil pressure sensor attachment structure

An oil pressure sensor attachment structure in which an oil pressure sensor for measuring a pressure of oil flowing in an oil path through which the oil flows is attached to an oil path body having the oil path therein,

• wherein the oil path body has an oil path opening portion which is opened to the upper side of the oil path body and is connected to the oil path,
• wherein the oil pressure sensor has a sensor main body, and a sensor case which covers the sensor main body,
• wherein the sensor case has a sensing hole which is connected to the oil path opening portion on the lower surface of the sensor case in a state where the oil pressure sensor is attached to the oil path body,
• wherein the oil pressure sensor attachment structure comprises:
• the oil path body;
• the sensor case;
• and
• a fixing member which fixes the sensor case to the oil path body,
• wherein 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,
• wherein 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 flange portion against the oil path body, and
• wherein the fixing portion and the pressing portion are disposed with an interval therebetween.
