Embodiment Construction

[0050]Next, a fuel pump support structure according to a first embodiment of the present invention will be described with reference to the drawings. In addition, directions such as front, rear, left, and right in the following description are the same as the directions of the vehicle unless otherwise specified.

[0051] Such as figure 1 as shown, figure 1 The small motorcycle 1 shown has front wheels 3 , which are steered by a steering handle 2 , and rear wheels 4 , which are driven by a pivoting drive unit 10 . Steering system components including the steering handlebar 2 and the front wheels 3 are pivotably supported by a head pipe 5 a at the front end of the body frame 5 . On the lower rear side of the vehicle body frame 5 , the front lower side of the power unit 10 is pivotally supported so as to be able to swing up and down. Between the handle bar 2 and the driver's seat 6 supported on the rear part of the vehicle body is a lower part, and a pedal 7 for the driver to p...

Abstract

The invention provides a supporting structure for a fuel pump capable of reducing the burden of sealing members and facilitating positioning and fixing. An insertion port for inserting the fuel pump (29) is formed on a fuel tank (25), and a pump connection part 41 is arranged on the periphery of the insertion port. A protrusion part 33 facing towards the periphery of the insertion port is arranged on the fuel pump, and a sealing member is arranged between the protrusion part (33) and the periphery of the insertion port. The fuel pump (29) is fixed onto the fuel tank (25) through a setting plate (60) connected with a pump connection part (41), wherein the setting plate (60) has a holding part (62) flexibly holding the fuel pump (29) by force generated due to curvature of the plate, and a pulling-out block part (63) restricting the movement of the fuel pump (29).

Description

technical field [0001] The present invention relates to a support structure of a fuel pump used in a vehicle such as a motorcycle. Background technique [0002] Conventionally, for the support structure of the fuel pump built in the fuel tank, the known support structure of the fuel pump is that the fuel pump is inserted through the opening provided in the fuel tank, and the flange part provided on the side of the fuel pump is connected to the fuel pump. The peripheral edges of the openings face each other, and the flange portion is held via a holding member connected to the fuel tank side, whereby the fuel pump is fixed to the fuel tank. The installation plate constituting the holding member is connected to the pump connecting member located on the fuel tank side outside the flange portion of the fuel pump. There is a seal, and the seal is broken by the pressure at the time of connection, and the fuel pump is positioned and fixed by the reaction force of its pressing (for ...
