Abstract: A process for producing gas hydrate pellets includes generating a gas hydrate by reacting raw gas and raw water under predetermined temperature and pressure conditions, and then shaping the gas hydrate into pellets by means of a pelletizer. Newly-formed gas hydrate or still-moist gas hydrate that has been partially dehydrated is shaped into pellets by means of a pelletizer, the shaping being conducted under conditions of the gas hydrate formation temperature and formation pressure. Subsequently, the shaped pellets are cooled to a sub-zero temperature by means of a refrigerating machine.

Abstract: A radiator grille is provided between the radiator and the front fender without elongating the wheel base of the motorcycle. The radiator grille includes a plurality of vertically long louvers. The forward projecting distance of the louvers is shorter for louvers near the body center and longer for louvers further away from the body center. As a result, the forward ends of the louvers are located outside the rotation locus inscribed by the rear of the front fender. Furthermore, the inclination angle formed between the louver and a vertical reference line is larger for outer louvers than for inner louvers.
