Document Type and Number:
WIPO Patent Application WO/2023/238316
Kind Code:
A1
Abstract:
This transmission device (1) comprises: a shift fork (110) that moves integrally in the axial direction with a slider (40) provided to a power transmission shaft (10); and a shift drum (130). The shift drum has a guide groove (140) in which a pin part (114) of the shift fork is disposed on the outer peripheral portion thereof, and when the shift drum has rotated about a rotational center axis parallel to the axial direction, the shift fork is moved in the axial direction in accordance with the position of the guide groove contacted by the pin part. The shift drum has a first contact part (150) provided at a position separated from the guide groove on the outer peripheral portion. The shift fork has a second contact part (115) provided at a position separated from the pin part. The first contact part and the second contact part are configured such that, when the shift drum rotates, contact between the first contact part and the second contact part moves the shift fork in the axial direction from a position to which the shift fork is guided by contact between the guide groove and the pin part.
