[

The operation of the embodiment of the present invention will now be described.

First, the operation of the shift mechanism unit 1 and the select mechanism unit 3 for selecting a specific stage of the transmission will be described as follows. First, the operation of the shift mechanism 1 will be described. The worm gear 17 provided on the shaft of the shift motor 11 rotates when the shift motor 11 receiving the drive signal is operated. When the worm gear 17 rotates, the worm wheel gear 19 rotates. Since the worm wheel gear 19 is integrally coupled with the screw member 13, the screw member 13 rotates together with the worm wheel gear 19 as the worm wheel gear 19 rotates. When the screw member 13 is rotated, the moving member 15 moves in the axial direction of the screw member 13. Since the shifting member 15 is provided with the latching portion 15a and the latching portion 15a is fitted in the groove portion 35a of the shift member 35, the shift member 35 moves. As the shift member 35 moves, the driven gear 25, the first finger 29, and the second finger 33 move together.

Then, the protruding portion 29a of the first finger 29 or the protruding portion 33a of the second finger 33 is located at the end where the shift is desired.

Then, when the select motor 21 is driven, the worm gear 37 coupled to the select motor 21 rotates, and the worm gear 37 rotates the worm wheel gear 39. As the worm wheel gear 39 rotates, the driving gear 23 coupled to the same shaft as the worm wheel gear 39 rotates. As the drive gear 23 rotates, the driven gear 25 rotates.

4, the first finger 29 is rotated by the first one-way clutch bearing 27 and the second one-way clutch bearing 27 is rotated by the first one-way clutch bearing 27. At this time, The second finger 33 does not rotate by the finger 31. Conversely, when the driven gear 25 rotates in the direction indicated by the dotted arrow, the first one-way clutch bearing 27 is in a stopped state by the first one-way clutch bearing 27 and the second one- The finger 33 rotates in the direction of the dotted arrow. This structure is a result of arranging the first one-way clutch bearing 27 and the second one-way clutch bearing 31 to rotate in opposite directions to each other. Therefore, the first finger 29 and the second finger 33 can rotate independently of each other.

When the first finger 29 or the second finger 33 is rotated, the protrusions 29a and 33a are rotated together with the first finger 29 or the second finger 33 so that the first finger 29 or the second finger 33, The protruding portions 29a and 33a of the first shift fork 33 are disposed in the first shift fork 7 or the second shift fork 9 in a direction perpendicular to the groove 35a.

At this time, when the shift motor 11 is driven again, when the first finger 29 and the second finger 33 move in the axial direction according to the above description of the operating structure, the first shift fork 7 or the second shift fork 9). Therefore, the speed change stage of the transmission can be changed by such an operation.

Such an embodiment of the present invention can reduce the number of parts, reduce the number of assembling processes and manufacturing costs, reduce the weight, and facilitate modularization.

Further, the embodiment of the present invention is characterized in that the number of the first and second fingers is increased by simply arranging the protruding portions provided at the first finger or the second finger at intervals so that the number of the first and second fingers is simply increased, So that the degree of freedom of design can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
