    • A tensioner has a cylindrical member having multiple locking teeth, one or multiple locking pieces having locking teeth to be engaged with the locking teeth, and a locking piece receiving part to receive the aforementioned locking pieces. A shaft member is disposed inside the cylindrical member, and either the cylindrical member or the shaft member constitutes a thrust member that can be driven forward and backward by a biasing force. A ratchet mechanism allows the thrust member to move forward by the locking pieces riding over the locking teeth of the cylindrical member as they move in a reduced-diameter direction and constrains retraction of the thrust member by the locking pieces engaging with the locking teeth of the cylindrical member as they move in an increased-diameter direction. The locking teeth are all thread-like teeth having a lead angle.

    • A fuel supplying apparatus is disclosed that suppresses intrusion of oil mist into a negative pressure introducing inlet of an automatic cock and that, thereby, improves the degree of freedom of disposition. The negative pressure introducing inlet of the automatic cock is connected to a crankcase through a negative pressure communication path. The automatic cock is opened by a negative pressure generated in the crankcase and, thereby, a fuel supply path is opened that is for supplying fuel from a fuel tank to an internal combustion engine. The negative pressure communication path communicates with the air cleaner through a purge path that branches from the negative pressure communication path at a halfway point of the negative pressure communication path. The point at which the purge path branches from the negative pressure communication path is set to be at the lowest position of the negative pressure communication path to be able to collect the oil mist intruding from the crankcase.
