연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A motorcycle comprising a frame, a front wheel coupled to the frame, and a rear wheel coupled to the frame. An engine is supported by the frame and is adapted to propel the motorcycle. An oil tank is supported by the frame and includes an inlet defining an inlet aperture having an inlet axis. An oil tank cap is rotatable about the inlet axis between an inserted position and a sealed position. The oil tank cap has a movable portion that is movable substantially along the inlet axis between a retracted position and an extended position.

What is claimed is: 1. A motorcycle comprising: a frame; a front wheel coupled to the frame; a rear wheel coupled to the frame; an engine supported by the frame and adapted to propel the motorcycle; an oil tank supported by the frame and including an inlet defining an inlet aperture having an inlet axis; and an oil tank cap rotatable about the inlet axis between an inserted position and a sealed position, the oil tank cap having a movable portion movable substantially along the inlet axis between a retracted position and an extended position, wherein the outer surface of the movable portion is not planar. 2. The motorcycle of claim 4, wherein the movable portion includes an outer surface and the oil tank includes an outer surface, and the outer surface of the oil tank cap is flush with the outer surface of the oil tank when the oil tank cap is in the sealed position and the movable portion is in the retracted position. 3. The motorcycle of claim 2, wherein the oil tank includes a cover member and the outer surface is an outer surface of the cover member. 4. The motorcycle of claim 1, wherein the outer surface of the movable portion is not symmetrical about the inlet axis. 5. The motorcycle of claim 1, wherein the oil tank includes a protrusion and the oil tank cap includes a recess sized to receive the protrusion, the recess located such that the oil tank cap is oriented in a first orientation when in the inserted position. 6. The motorcycle of claim 5, wherein the recess includes a groove, and the protrusion moves along the groove during rotation of the oil tank cap between the inserted position and the sealed position. 7. The motorcycle of claim 1, wherein the oil tank includes a first protrusion and a second protrusion and the oil tank cap includes a first recess and a second recess and wherein the first recess is sized to receive only the first protrusion. 8. The motorcycle of claim 7, wherein the first recess includes a first helical groove and the second recess includes a second helical groove. 9. An oil tank cap for an oil tank having an inlet defining an inlet aperture and an inlet axis, the cap comprising: a first portion adapted to be inserted into the inlet, the first portion rotatable about the inlet axis between an inserted position and a sealed position; and a second portion mounted to the first portion and movable parallel to the inlet axis relative to the first portion between a retracted position and an extended position, wherein the orientation of the second portion is substantially fixed relative to the first portion. 10. The oil tank cap of claim 9, wherein the second portion includes an outer surface and the oil tank includes an outer surface, the outer surface of the second portion adapted to be flush with the outer surface of the oil tank when the first portion is in the sealed position and the second portion is in the retracted position. 11. The oil tank cap of claim 10, wherein the oil tank includes a cover member and the outer surface of the oil tank is an outer surface of the cover member. 12. The oil tank cap of claim 9, wherein the first portion includes a recess sized to receive an oil tank protrusion, the recess located such that the first and second portions are oriented in a first orientation when in the inserted position. 13. The oil tank cap of claim 12, wherein the recess includes a groove, and the protrusion moves along the groove during rotation of the first and second portions between the inserted position and the sealed position. 14. The oil tank cap of claim 9, wherein the oil tank includes a first protrusion and a second protrusion and the first portion includes a first recess and a second recess and wherein the first recess is sized to receive only the first protrusion. 15. The oil tank cap of claim 14, wherein the first recess includes a first helical groove and the second recess includes a second helical groove. 16. The oil tank cap of claim 9, wherein the first portion includes a first recess and a second recess wider than the first recess. 17. An oil tank cap for an oil tank having an inlet defining an inlet aperture and an inlet axis, the cap comprising: a first portion adapted to be inserted into the inlet, the first portion rotatable about the inlet axis between an inserted position and a sealed position; and a second portion mounted to the first portion and parallel to the inlet axis relative to the first portion between a retracted position and an extended position, wherein the second portion includes an outer surface and the oil tank includes an outer surface, the outer surface of the second portion adapted to be flush with the outer surface of the oil tank when the first portion is in the sealed position and the second portion is in the retracted position, and wherein the outer surface of the second portion is not planar. 18. The oil tank cap of claim 17, wherein the outer surface of the second portion is not symmetrical about the inlet axis when the first portion is engaged with the inlet. 19. A method of assembling an oil tank having an inlet defining an inlet aperture and an inlet axis, the method comprising: engaging an oil tank cap with the inlet; rotating the oil tank cap about the inlet axis from an inserted position to a sealed position; moving a movable portion of the oil tank cap from an extended position to a retracted position; maintaining the movable portion of the oil tank cap in the retracted position; and matching the contour of the outer surface of the oil tank cap with the contour of the outer surface of the oil tank when the oil tank cap is in the retracted and sealed positions, wherein moving the movable portion includes moving the movable portion such that an outer surface of the oil tank cap is substantially flush with an outer surface of the oil tank. 20. The method of claim 19, wherein moving a movable portion includes pressing and releasing the movable portion.
