Abstract

Provided is a scooter type motorcycle in which a storage box that is capable of storing luggage is provided under a double seat, a unit-swing type engine unit comprising an engine and a power transmission device integrated as a single body is mounted in a lower part of the vehicle under the storage box, and a fuel tank is provided in the lower part of the vehicle in front of the engine unit, wherein a canister, which can temporarily collect fuel evaporation gas generated in the fuel tank and supply the fuel evaporation gas to a cylinder assembly forming part of the engine, is provided in front of the cylinder assembly and above the rear part of the fuel tank to thereby make it possible to control the fuel evaporation gas.

Description

technical field [0001] The present invention relates to a scooter having a canister that temporarily collects fuel evaporated gas generated in a fuel tank and can supply the gas to an engine side, and enables control of fuel evaporated gas. Background technique [0002] Conventionally, in the fuel tank of a motorcycle, the stored fuel may be vaporized and stagnated in the upper part of the fuel tank as fuel evaporated gas. There is known such a fuel vapor control technology: In order to prevent the fuel vapor gas from leaking into the atmosphere when the engine is stopped, the fuel vapor gas is introduced into the canister for temporary collection, and the fuel vapor gas in the canister is drained when the engine is started. supplied to the engine side. [0003] As an example of such a device, Patent Document 1 discloses such a small motorcycle: a storage box is arranged under the seat, an engine unit is arranged below the storage box, and an engine unit is installed in the...
