Patent number: 9579971Abstract: In a fuel cap provided with a breather mechanism, a cap openably and closably covers a fuel filler of a fuel tank. The cap includes a breather passage for communication between the inside and the outside of the fuel tank. The breather passage is provided with a breather valve mechanism and a resonator chamber as a silencing mechanism. The breather mechanism is a valve having a spring capable of retaining a pressure within the fuel tank up to a predetermined pressure.Type: GrantFiled: August 6, 2014Date of Patent: February 28, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Takuma Koishikawa, Takeshi Uemae, Takashi Toriki, Yoji Fukui, Takumi Sakamoto, Takeshi Shimura, Shinji Kobayashi, Satoshi Okayama

Patent number: 9045187Abstract: A saddle-ride type vehicle that does not require dismounting of a handhold regardless of the presence or absence of a carrier member. A stay member includes an outer portion situated beyond a seat in the outward direction of the vehicle body. A recess dented upwardly is formed in an underside of the outer portion. Because the recess is formed in the underside of the outer portion, a pillion passenger can grasp the recess after a carrier member has been dismounted from the stay member. In short, the recess serves as a handhold. The stay member remains attached to a seat rail either when the carrier member is mounted or dismounted. This eliminates the need to detach the handhold regardless of the presence or absence of the carrier member.Type: GrantFiled: May 24, 2013Date of Patent: June 2, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Yoji Komatsu, Takuma Koishikawa, Keita Mikura
