Abstract: An exhaust pipe has an upstream-side exhaust pipe extending downward from an engine to house a catalyst for exhaust gas purification, and a downstream-side exhaust pipe located downstream of the upstream-side exhaust pipe, and extending upward from the catalyst and then bending downward. Under a configuration in which an exhaust pipe is disposed below an engine, with a simple configuration, a catalyst is hardly exposed to water.

Abstract: The agent for the prevention and/or treatment of Hand-Foot Syndrome comprising a compound with anticholinergic activity can be provided. The agent for the prevention and/or treatment of Hand-Foot Syndrome comprising a compound with anticholinergic activity can be safely administered to the patients with Hand-Foot Syndrome, and has shown the superior preventive and/or treatment effect against Hand-Foot Syndrome.

Abstract: An exhaust fan chamber is defined with a belt cover and a fan cover provided over the belt cover, and an exhaust fan is accommodated in the exhaust fan chamber. The fan cover has an air intake port for sucking air within an engine cover into the exhaust fan chamber and an exhaust outlet port for discharging air within the exhaust fan chamber to outside of the exhaust fan chamber. The exhaust outlet port is in communication with an exhaust opening formed in an upper portion of the engine cover so that the air discharged through the exhaust outlet port is discharged to outside of the engine cover through the exhaust opening.

Abstract: An outboard engine is disclosed that includes an idling chamber that communicates with a guiding outlet of a first exhaust path and that is open to the atmosphere. The idling chamber includes a cooling water communicating path that communicates with a cooling water supplying path, and a pressure adjusting valve that opens the cooling water communicating path when the value of the water pressure in the cooling water supplying path reaches a threshold value. When the value of the water pressure in the cooling water supplying path reaches the threshold value, the pressure adjusting valve opens and a portion of cooling water is guided to the idling chamber through the cooling water communicating path.

Abstract: The invention provides a fuel supply device, which is possible to prevent undesired water entered into a fuel path from remaining therein with a simple arrangement. A fuel supply pipe for supplying fuel to each of the fuel injection valves of an engine disposed with a plurality of cylinders in a vertical direction includes a fuel path in longitudinal direction, a smaller diameter portion formed perpendicular to the fuel path and continuous with a fuel injection valve mounting hole, and a cap attached to a lower end of the fuel path. The cap is arranged so that the upper end of its protruding portion is positioned at the same or nearly same level as that in height of the smaller diameter portion. Thus, the water entered in the fuel supply pipe is exhausted through the smaller diameter portion without delay.
