Abstract: A closure cap for a liquid storing vessel or tank which is constructed with a liquid storing tank having a liquid filling port formed in a predetermined part thereof, a mouth piece fitted in the liquid filling port and having an inwardly extending flanged part, a closure cap to be fitted in the mouth piece in the liquid filling port, a sealing member interposed between the lower surface of the closure cap and the inwardly extending flanged part of the mouth piece fitted in the liquid filling port, a ring-shaped raised part formed between the top peripheral edge of the mouth piece and the inwardly extending flanged part thereof, a ring-shaped flat plate part forming a part of the sealing member to intimately contact with the lower surface of the closure cap, a ring-shaped lip part which is integrally joined with the lower part of the ring-shaped flat plate part through a connecting part and which is intimately contacted with a downwardly inclined inner peripheral surface of the ring-shaped raised part defined

Abstract: Apparatus for preventing fuel from leaking on accidental turnover of a vehicle, the latter having a fuel tank, a carburetor and a passage communicating the tank with the carburetor, the apparatus comprising an ordinarily open safety valve such as a ball valve interposed in the passage, so arranged that, on the turnover of the vehicle, a pendulum-type weight detects the inclination of the vehicle, operating a cam to automatically close the safety valve. An optional fuel cock may be provided, for manual operation, interposed in the fuel passage, while the safety valve has a housing integrally formed therewith on one of its sides.

Abstract: A fitting device for wind shield, wherein a wind shield plate is fixed directly to the body of a motor-cycle or to a fairing surrounding the motor-cycle body by means of threaded bolts and nuts which are breakable upon external shock being imparted to the wind shield plate, and the center portion of the wind shield plate is particularly held by a hinge, etc. which is swingable in the frontward direction alone so that, when excessive impact force is applied to the windshield, it falls frontward, thereby preventing the wind shield plate from flying backward to hit a motor-cycle rider or any person nearby.
