POWER SUPPLY PLUG DEVICE

PURPOSE: To enhance assembling capability by making fixing work easy and substantially enhance the performance of a bearing part and click mechanism. CONSTITUTION: Shafts 6x, 6y formed in a pin block 5 having a pair of plug pin parts 3x, 3y are supported so as to be capable of rotating with bearing parts 2x, 2y formed on the inside of a casing C, the plug pin parts 3x, 3y are protruded from an opening part S of the casing C to the outside, and the plug pin parts 3x, 3y are constituted so as to be capable of selectively displacing to a using position Pu or a housing position Pi. The bearing parts 2x, 2y are separately formed from the casing C and support the shafts 6x, 6y of the pin block 5 so as to be capable of rotating, and a supporting block 8 has fixing parts 7x, 7y for fixing to the casing C.
