PROBLEM TO BE SOLVED: To smooth an assembling work by heightening positioning accuracy of components. SOLUTION: Positioning projections 36, 37 of a spacer 35 are interfitted respectively firmly into a positioning hole 23 of a detection circuit board 21 and a positioning hole 38 of a display circuit board 32, to thereby position both boards mutually. A positioning projection 16 of a rear case 6 is interfitted firmly into a positioning hole 22 of the detection circuit board 21, to thereby hold the detection circuit board 21 in the rear case 6 in the positioned state. After assembling a pressure detection means 3, a display means 4 or the like successively in the rear case 6, a front case 5 is engaged with the rear case 6. Hereby, since the pressure detection means 3, the display means 4 or the like are sandwiched between both cases 5, 6, assembly can be performed simply. COPYRIGHT: (C)2007,JPO&INPIT
