<p><P>PROBLEM TO BE SOLVED: To provide a gas cord connection structure determining that a connection state of a plug and a joint member is a normal connection state in a non-contact state which does not require mechanical operation and electrical contact with the outside. <P>SOLUTION: In the gas cord connection structure with respect to the plug 40, a sleeve member 34 is constituted by a magnetic material for changing the magnetic flux of a coil 51 provided on the plug 40 side in the normal connection state where the plug 40 and the joint member 20 are interconnected to permit gas to flow between a gas cord 10 and an inner fluid flow passage 46. The gas cord connection structure is provided with a connection state determination means A for determining the normal connection state based on change in the inductance of the coil 51. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
