PROBLEM TO BE SOLVED: To make freely settable the acceleration detection direction by setting an acceleration sensor together with a circuit board to a connector member and making the connector member rotatable with respect to a casing. SOLUTION: The connector member 20 is coaxially inserted from a supporting plate part 23 into a cylindrical body 10a of a casing 10 through an opening part of the casing, and tightened by a screw 15 via a washer 15a and a central part of a bottom wall of the cylindrical body 10a at a leading end face of the supporting plate part 23. At this time, an outer circumferential part of a disc part 22 is fitted in a circumferential wall 11 of the cylindrical body 10a along an inner face of the wall. Accordingly the connector member 20 is supported in the cylindrical body 10a of the casing 10 coaxially and freely mountably to a desired position. A circuit board 40 is secured to an outer wall of one side of the supporting plate part 23, and an acceleration G sensor 30 is loaded to a surface of the circuit board 40. A detection direction of the G sensor 30 is made parallel to the surface of the circuit board 40. The G sensor 30 is electrically connected through the circuit board 40 to inner end parts of both of connector pins of a connector part 21. |
