Abstract: A vehicle transmission structure of an embodiment includes a shift drum which rotates in accordance with a shift operation; a bearing member which rotatably supports the shift drum with respect to a transmission case; a set member which positions the bearing member; a shift fork shaft supported by the transmission case; and a shift fork supported by the shift fork shaft to be movable in an axial direction. An end portion of the shift fork shaft is movably fitted to an insertion hole provided in the transmission case, a cap is provided at an end portion of the shift fork shaft, a first gap is provided between an end surface of the insertion hole and the cap, the set member is disposed at a position overlapping the insertion hole when viewed in the axial direction, and a second gap is provided between an end surface of the insertion hole and the set member.

Abstract: A stroke start position is detected by a change amount of a clutch hydraulic pressure that has become smaller than a negative predetermined value ?P1 during clutch connection control by a clutch actuator, and a stroke end position is detected by a change amount of the clutch hydraulic pressure that has become larger than a positive change amount ?P2. By using a proportional function formed by a stroke start hydraulic pressure Ps detected at the stroke start position and a stroke end hydraulic pressure Pe detected at the stroke end position, a target half-clutch hydraulic pressure Ph that generates a predetermined target half-clutch capacity in a predetermined half-clutch state between the stroke start position and the stroke end position is calculated. By using the target half-clutch hydraulic pressure Ph, a clutch control amount in the predetermined half-clutch state is determined.
