Abstract (en)

A new type of plug incorporating a normally closed valve for draining oil from an oil pan of a car engine, wherein the normally closed valve is incorporated in a through hole (113) provided as an oil draining path in a bolt type member (11) fixed to the oil pan (102), an oil draining dedicated jig (7) is assembled to the plug so as to open the normally closed valve in order to drain the oil contained in the oil pan (102) by sucking it with a negative pressure, a movable valve disc member (13) installed in the through hole (113) is installed so that it is engaged with a valve seat (121) provided near the outer end part of the through bole (113) by a coiled spring (14) so as to form the normally closed valve, and the tip end of the plug is made flush generally with the internal surface of the oil pan so as to prevent any structure from projecting toward the inside. <IMAGE>
