  • Patent number: 8821346
    Abstract: A clutch actuator unit is provided that includes a housing having a mounting space and a penetration aperture for receiving an operating rod. A slide pad and slider are disposed along an inner side surface of the mounting space, and are configured to move back and forth within the housing. An operating rod that is connected to the slider through the penetration aperture is moved back and forth, along with the slider and slide pad, through the aperture via a drive portion. A stopper is also integrally formed along the front surface of the slide pad to limit the movement of the slider accordingly. In doing so, the disclosed actuator is able to dynamically locate certain stroke positions and provide an improved shifting operation.
