<P>PROBLEM TO BE SOLVED: To provide a pressure sensor which reduces weight and size, improve the efficiency of assembling work, and can be disassembled. <P>SOLUTION: While an upper end surface of a lower frame 80 in a pipe member 20 abuts on a lower end surface of an upper frame 50 in an upper case 10, the lower frame 80 is fixed on the upper case 10 by a plurality of screws 17a. A flange upper end surface 82a of the lower frame 80 abuts on a projecting part lower end surface 24e of the pipe member 20. An upper end portion of the pipe member 20 is held by a lower end surface of a large-diameter portion 13 of the upper case 10 through an upper end portion of a design ring 90. Therefore, the pipe member 20 is sandwiched between the upper case 10 and the lower frame 80. A display substrate 40 is attached in the upper case 10. In the pipe member 20, a power supply substrate 60 and a main substrate 70 are held in an axial direction by the upper frame 50 and the lower frame 80. <P>COPYRIGHT: (C)2012,JPO&INPIT |
