<p><P>PROBLEM TO BE SOLVED: To screw a pressure sensor into a mounting hole in an engine block without allowing a seal member to be affected by friction and an axial deflection caused by turns of a screw. <P>SOLUTION: The pressure sensor 100 includes a cylindrical body 1 having a pressure receiving part 11 at one end and inserted into the mounting hole 201 from one end which is provided with the seal member 300. The other end of the body 1 is provided with a separately composed screw member 3 having a first threaded part 3a, an inner surface of the mounting hole 201 has a second threaded part 203, and screwing is performed by both the threaded parts 3a and 203 by turning the screw member 3 around an axis of the mounting hole 201. Since there is a clearance between the body 1 and the screw member 3, the body 1 is not turned together with the screw member 3 while the screw member 3 is turned. The screw member 3 is provided with a retaining part 3b pressing the body 1 against the mounting hole 201 by a binding force of screwing. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
