<P>PROBLEM TO BE SOLVED: To provide a buckle device with an attached switch which reliably restricts an influence of an external magnetic field and which can easily configure the switch without an error. <P>SOLUTION: The buckle device 10 with a switch, includes a switch 40 having a hole element 36 capable of signals according to the magnitude of a magnetic flux density, a magnet 37 for applying a magnetic field to the hole element 36, and a shielding plate 23 fitted to an ejector 24 so as to be operated in conjunction with each other to change the magnitude of the magnetic flux density applied from the magnet 37 to the hole element 36 according to the position of the ejector 24. The hole element 36 and the magnet 37 are magnetically shielded by at least a frame 21 and a latch member 22 formed of magnetic members. <P>COPYRIGHT: (C)2013,JPO&INPIT |
