PROBLEM TO BE SOLVED: To provide an intake pipe vacuum device capable of maintaining a favorable locking state and increasing the degree of freedom of the selection of the draw-out direction of a connector of a sensor case without enlarging a positioning projection of the sensor case and a positioning hole of a pressing plate. SOLUTION: The equilateral hexagon positioning projection 2 is formed at an upper part of the sensor case 1. The pressing plate 4 has a first hexagon positioning hole 5 formed with face angle recesss 5a, 5, ... a second hexagon positioning hole 6 shifted from the first hexagon positioning hole 5 by 30 degrees. An apex 5a1 of the first face angle recess 5a of the first hexagon positioning hole 5 is arranged to be inclined by 7.5 degrees with respect to a base line X-X. A mounting hole 7 and a positioning hole 8 formed at the pressing plate 4 are arranged on symmetrical positions with respect to the base line X-X. The draw-out direction of the connector can be selected from 24 positions by using the pressing plate 4 by reversing a front and a back with respect to the base line X-X. COPYRIGHT: (C)2007,JPO&INPIT
