<p>PROBLEM TO BE SOLVED: To prevent the gap at the joint section of a magnetic circuit from increasing due to foreign matters adhering to the joint surface of a secondary core. SOLUTION: An electric automobile is provided with an oscillating lid 40 for closing/opening a recessed section 13 which is provided to house a secondary core unit and a cleaning member 47 is attached to the front end of a mechanism section 41 which is protruded from the internal surface of the lid 40 so that the member 47 may collide with the joint surface 23 of a secondary core 21 when the lid 40 is closed. The mechanism section 41 is constituted by fitting a shaft 43 into a cylinder 42 protruded from the lid 40 so that the shaft 43 may be rotated while moving in the axial direction when a projecting section 45 is engaged with a spiral groove 44 formed on the fitting side surface of the cylinder 42. When the lid 40 is opened from the closing state, the cleaning member 47 rotates and cleans the joint surface 23 of the core 21 by wiping while a coil spring 46 presses the member 47 against the surface 23.</p> |
