The utility model discloses a gear shifting device for transmission, which relates to the technical field of automobile manufacturing, including a gear shifting cam mounted in the cover shell by a gear selection shaft, a gear shifting rocker arm and a gear shifting head mounted on the gear selection shaft, an arc-shaped slot for the gear shifting cam, a gear shifting positioning pin mounted on the cover shell, a movable connection between the gear shifting head and the gear shifting fork, and a slotted shift shifting fork. The movable block and the shifting head are provided with convex blocks which are opposite to the walls on both sides of the groove; the shifting cam is located on both sides of the arc limit groove with inclined planes, and the shifting head is provided with sockets; the groove opening of the shifting block is relatively provided with two limit parts extending into the socket, and the limit part is movably pressed with the shifting shaft. Compared with the existing technology, the shifting stroke of the utility model is limited by the matching of the shifting block and the shifting shaft. The distance between the two limiting parts of the shifting block and the processing error of the diameter of the shifting shaft can be easily controlled within a smaller tolerance range. The range of the shifting stroke tolerance is greatly reduced and the shifting positioning is accurate.
