In a cap device, a long, flexible coupling member is coupled at one end to a cap for opening and closing an inlet, and it is slidably mounted at the other end to a guide member located near the inlet. A rotary ring is rotatably mounted around the cap, and the coupling member is coupled to a part of the rotary ring at one end thereof. Slanted blocks for removing foreign materials are provided on a portion of the rotary ring which slides with respect to the circumferential outer surface of the cap. A slide support member formed another end of the coupling member is guided by a guide member disposed on the back side of the oil filler lid. The guide member guides the slide support member in such a direction that the slide support member slides apart from a hinge.
