The manual transmission includes a shift select shaft, a connecting member, a lever member, a guide pin and a guide plate, wherein the connecting member, the lever member, the guide pin and the guide plate are arranged so that under a state that the guide pin and the guide plate are engaged at the engaging portion, assuming that the portion of the shift select shaft is a fulcrum, the connecting portion is a point of effort, the engaging portion is a point of load and that the fulcrum, the point of effort and the point of load exist on a same virtual plane, an operation direction of a reaction force generated at the point of load becomes a direction opposite to the operation direction of the operation force inputted to the point of effort.

Disclosed herein is a gear actuator for a double clutch transmission, which includes a power module (100), including odd and even-numbered stage select solenoids and shift motors, a controller directly connected to them, and select levers connected to select rods of the select solenoids, shift modules (200) for transmitting the rotational forces of the shift motors to a control shaft assembly (300), the control shaft assembly (300) for transmitting the operating force of the power module (100) to a shift lug, and a body housing (400) having the power module (100), the shift modules (200), and the control shaft assembly (300) installed therein. Accordingly, the gear actuator can have a more compact structure and be easily assembled by modularization.

A coupling arrangement is disclosed for coupling a gearshift and a shift operator with a selector shaft for a manual transmission of a motor vehicle. The coupling arrangement has a transmission member with a first section on the gearshift side and a second section on the selector shaft side. The transmission member is displaceably mounted by a guide and is deflected by at least 45.

A control device within an actuator includes control logic for a second actuator, the second actuator being connected with the first actuator through a communications interface. By storing the control logic in the second actuator, the construction space for this second actuator is optimized. By integrating the control logic into a control device of the first actuator, the power density of the control device is increased.
