Problems solved by technology

However, in this case, the engine mount 314 becomes heavier thereby increasing the overall weight of the vehicle body
[0005] Since the floor support 315 has a U-shaped section, its rigidity is insufficient
If you increase the stiffness of the front and rear of the floor support, it will increase the weight of the car body

Abstract

A frame structure (210) for a scooter type vehicle 10 having a vehicle body frame (11) and a floor panel (222) provided on the vehicle body frame (11) is provided. The frame structure (210) includes a main pipe (71) extending rearwardly from a lower end of a head pipe (211), and a first cross pipe (74) coupled to a rear end of the main pipe (71). The first cross pipe has opposite ends to which engine hanger brackets (77, 77) for supporting an engine are welded. Left and right floor supporting frames (217, 217) for supporting the floor panel are each welded to the engine hanger bracket (77) within a range (274) of welding at the outer periphery of the first cross pipe (76).

Description

Technical field [0001] The present invention relates to a frame structure of a scooter-type vehicle, in which a floor pedal of a low deck is installed on the main frame of the vehicle. Background technique [0002] For example, a frame structure of such a scooter type vehicle is known from Japanese Patent No. 3006214. The known structure will be described below with reference to FIG. 9. [0003] The frame structure 310 of a conventional scooter-type vehicle includes a main pipe 312 extending backward and downward from a front pipe (not shown). The left and right rear frames 313 are installed to the rear of the main pipe 312 and extend backward and upward from there. The engine mount 314 is mounted to the rear of the main pipe 312 and the front of the left and right rear frame 313. The floor support 315 having a U-shaped cross-section extends from the engine mount 314 in the side direction of the scooter-type vehicle. The cross beam 316 extends from the lower part of the main pipe...
