    摘要： An automatic transmission comprising a planetary gear mechanism having a first gear driven from a drive shaft, a second gear engagable with the first gear to transmit speed change output to a driven shaft, and a third gear engagable with the second gear to control the operation thereof. A centrifugally operated clutch operates to directly connect the first gear and second gear when the rotational speed of the driven shaft exceeds a predetermined value, and a ratchet type one-way clutch is disposed between the third gear and a fixed construction member to permit rotation of the third gear in the same direction as that of said drive shaft but prevent rotation in the reverse direction. The ratchet type one-way clutch comprises a ratchet pawl supporting plate integrally connected to the third gear, a supporting member having annular ratchet teeth adjacent the supporting plate and fixedly mounted on the fixed construction member, and at least two ratchet pawls rotatably supported on the supporting plate for movement under centrifugal force to engage and disengage the ratchet teeth. The pawls are spaced on the supporting plate so that the pawls are angularly offset with respect to the teeth whereby the pawls can not engage the ratchet teeth concurrently and preferably the pawls are angularly offset with respect to the ratchet teeth by one-half of the pitch of one tooth.

    摘要： A four-wheel vehicle for traveling on an irregular road that is superior in weight balance and traveling stability. A rotating section (radial center line L3) of a torque converter T and a drive shaft (longitudinal center line L2) which transmits a driving force from a transmission mechanism M to front or rear wheels, are distributed right and left in an opposed relationship to each other with respect to a longitudinal center line (L1) of a vehicle body.

    摘要： A transmission for changing a ratio of a rotational number of a power source and a rotational number of an output shaft by shifting a gear train provided between the power source and the output shaft by moving a shift fork. The transmission includes a shift drum for moving the shift fork, a clutch provided between the power source and the gear train, a shift spindle for urging the shift drum and the clutch. When the shift spindle is pivoted, lift of a clutch is started by pivoting a clutch arm. In accordance with pivoting the shift spindle, a sub arm is pivoted and preload is applied on a master arm by a preload spring. Thereafter, when the sub arm is further pivoted, the master arm follows the sub arm and a shift drum is pivoted via index pins. Since the preload is applied, when the clutch is disengaged, the shift drum is pivoted immediately, a shift fork is displaced and gears are switched.
