Abstract

The present invention provides a frame structure of a scooter-type vehicle. The scooter-type vehicle (10) includes: a head pipe (12) that supports a front fork (13) so as to be steerable; A hollow main pipe (20); a pair of left and right bottom frames (30L, 30R) combined with the lower part of the main pipe and extending from the bottom of the main pipe to the rear of the vehicle body; ) combined and extended along the vehicle width direction; and a pair of left and right rear frames in which the front ends (71L, 71R) are respectively combined with the left and right ends (63L, 63R) of the transverse tube and extended to the upper rear of the vehicle body (70L, 70R). The bottom frame and the rear frame are combined with the cross tube, and at least a part of the bottom frame is combined with at least a part of the rear frame.

Description

technical field [0001] The present invention relates to an improvement in the frame structure of a scooter-type vehicle. Background technique [0002] In a scooter-type vehicle, it is known to install a horizontal pipe on the left frame and the right frame in order to ensure rigidity (for example, refer to Patent Document 1). [0003] The vehicle body frame of the scooter-type vehicle disclosed in Patent Document 1 includes a lateral tube which is connected to the rear end of the underframe and supports the front end of the rear frame tube. [0004] The cross pipe extends linearly in the vehicle width direction, supports the left side underframe and the rear frame pipe, and supports the right side underframe and the rear frame pipe. [0005] In recent years, in order to improve fuel consumption, it has been desired to reduce the thickness of the frame and to reduce the weight of the frame. However, simply reducing the thickness of the frame may result in a reduction in the...
