Problems solved by technology

[0004] However, if the absorption tank is arranged so that its longitudinal direction is along the vehicle width direction as in the prior art, the vehicle width will increase.
In particular, in the structure of the prior art, since the width of the vehicle is increased around the storage box arranged under the seat, there is a possibility that the pedaling feeling of the occupant seated on the seat may be deteriorated.
[0005] In addition, since the discharge pipe connected to the fuel tank, the purge pipe connected to the engine side, and the discharge pipe are connected to both ends of the absorption tank in the longitudinal direction, the width of the vehicle is increased.

Abstract

The invention provides an evaporated fuel processing apparatus of a motor-driven cart which can prevent the large scale of vehicle width due to an absorption tank. The motor-driven cart (1) comprises an engine (7) supported by a vehicle frame (2), a fuel tank (34) storing fuel transmitted to the engine (7), a receiving casing (9) disposed at the lower side of a seat (8) and the absorption tank (203) which is disposed at the periphery of the receiving casing (9) and absorbs the evaporated fuel from the fuel tank (34). In the motor-driven cart (1), the length direction of the absorption tank (203) tilts with respect to the width direction of a vehicle.

Description

technical field [0001] The present invention relates to a treatment device for evaporated fuel of a motorcycle. Background technique [0002] There is a motorcycle having an evaporated fuel processing device that temporarily absorbs gaseous evaporated fuel generated by evaporation of fuel in a fuel tank into an absorption tank, and absorbs the gaseous evaporated fuel by using the intake negative pressure of the engine. The fuel adsorbed by the tank is supplied to the engine and combusted (for example, refer to Patent Document 1). In such a motorcycle, the absorption tank is arranged with its longitudinal direction along the vehicle width direction in the space between the storage box arranged under the seat and the cover covering the periphery of the storage box. [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 5-124560 [0004] However, if the absorption tank is arranged such that its longitudinal direction is along the vehicle width direction as i...
