A drive transmitting device includes a first gear; a second gear in engagement with the first gear; wherein a first tooth which is at least one of teeth of the first gear has a tooth surface contacting a tooth of the second gear, wherein the tooth surface has such a shape that a contact point of the first tooth of the first gear to the tooth of the second gear is in a region of a first gear side with respect to a line of action which is formed by movement of a contact point between a tooth of the second gear and a second tooth of the first gear immediately before the first tooth with respect to a rotational moving direction of the first gear.

The patent discloses a winding device with a speed regulating mechanism. The winding device with a speed regulating mechanism includes a device body and a winding wheel installed on the device body. The speed regulating mechanism is arranged on one side of the winding wheel and includes a transmission gear set and a speed regulating shifting rod. The transmission gear set includes a sliding output gear and a speed regulating transmission member. According to the winding device with a speed regulating mechanism, the speed regulating mechanism is installed in the winding device, through the regulation of the speed regulating shifting rod, the transmission efficiency of a water turbine can be changed, and the regulation of various winding speeds can be achieved. Moreover, an idling function can be fulfilled after an output shaft is pulled through a handle, which makes the winding wheel suspend moving.
