All you have to do is slide inside a, and change lever 5.
The shaft portion 56C of No. 6 is connected to the elongated hole 52bi of the shift plate 52.
The shift plate does not move as it only moves in the longitudinal direction.

Next, when the change lever 56, which is in the neutral position in the shift direction as shown in FIG. 9, is shifted in the direction shown in FIG. 10, the change lever 56 swings around the Hall bearing 58, and the shift plate 52 , moves integrally with the change lever 56 via the sliding # member 51 in the direction of the arrow. Then, when the shift magnet piece 54 reaches a position facing any one of the shift Hall elements 55 (FIG. 7), an electric signal, that is, a shift command signal is generated from the shift magnet piece 54 (FIG. 7). The transmission operating device operates to move the transmission soft fork to the position where one of the gears is selected, completing the shift operation.

At this time, the sliding member 51 is connected to the concave groove 4 of the select plate 46.
6a, and the change lever 56
shaft portion 56Cld, elongated hole 46b of select plate 46
The select plate does not move because it only moves in the longitudinal direction.

In order to select the change lever 56 in this way, as shown in FIG.
When shifting, move inside the groove 45a by arrow G or [)L.
In either case, the base 56a of the change lever 56, which is formed into a spherical shape, is supported by a ball bearing 58, and is swung in the select direction or the shift direction using the ball bearing as a fulcrum. Since the change lever is configured to move, the swinging mechanism of the change lever is simplified and smooth rotational movement can be obtained. Furthermore, it is slidably fitted into a groove 46a formed in the shift direction of a select plate 46 that can slide only in the select direction and a groove 52a formed in the select direction of a shift plate 52 that can slide only in the shift direction. Since the middle part 56b of the change lever 56 formed in a spherical shape is inserted into the through hole 51H of the inserted sliding member 51, the transition to the select position or the shift position can be confirmed by the response of the change lever 56. In addition, the select position or shift position can be set accurately and smoothly.

The present invention is constructed and operates as described above, and therefore, in a remote device for remotely controlling the gear shift of an engine transmission using an electro-pneumatic or hydraulic actuating device, the base of the change lever is spherical, and the base is pivotally mounted on a ball bearing, and the change lever swings in the select direction or shift direction using the ball bearing as a fulcrum, so that the swing mechanism of the change lever is This has the effect of being simplified, greatly reducing costs, and also providing smooth rocking motion and improving durability. In addition, the middle part of the change lever is spherical, and the middle part has a concave groove formed in the shift direction of the select plate that can slide only in the select direction, and a concave groove formed in the shift direction of the select plate that can slide only in the shift direction. Since it is inserted into the through hole of the sliding member that is slidably inserted into the groove formed in the select direction, the change lever can be moved to the select position or shift position reliably. In addition, it is possible to accurately and smoothly set the select position or shift position.
