Patent number: 11692620Abstract: There is provided a shift device for a straddle-type vehicle that is configured to cause a transmission device to perform a shift change in accordance with rotation of a shift shaft. The shift device includes: a shift lever provided with an operation portion that is configured to receive a shift operation; a shift sensor provided on the shift shaft so as to be integrally rotatable with the shift shaft; and a shift rod that couples the shift lever and the shift sensor. The shift sensor is configured to detect the shift operation on the shift lever in accordance with a movement of the shift rod. The operation portion and the shift sensor are positioned at the same side in a manner of sandwiching the shift rod.Type: GrantFiled: February 23, 2022Date of Patent: July 4, 2023Assignee: SUZUKI MOTOR CORPORATIONInventors: Kohei Kato, Takatoshi Maemori, Tatsushi Uchiyama, Hiroyasu Inohara
