Since the middle part 56b of the change lever 56, which is formed into a spherical shape, is inserted, it is possible to confirm the transition to the select position or shift position by the response of the change lever 56, and also to ensure that the select position or shift position is accurately set. It can be set quickly and smoothly.

Since the present invention is constructed and operates as described above, the present invention provides a remote device for remotely controlling the speed change of an engine transmission using an electro-pneumatic or hydraulic actuating device. The base of the change lever is spherical,
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 the swing mechanism of the change lever is simplified and costs are significantly reduced. In addition, smooth rocking motion can be obtained and durability can be improved. Further, the middle part of the change lever is spherical, and the middle part has a concave groove formed in the shift direction of a select plate that can slide only in the select direction, and a 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 direction, it is possible to reliably confirm the transition to the select position or shift position by the touch of the change lever. This also provides the effect that the select position or shift position can be set accurately and smoothly.
