Claim:
1. A linear actuator for a linear motion of a component of a camera, the linear actuator comprising: a supporting structure; a motor arranged on the supporting structure for generating a rotational movement, a component carrier for carrying a component and for performing the linear motion relative to the supporting structure; and a gear mechanism including a gear train with a plurality of gears for transmitting the rotational movement, whereby a last gear of the plurality of gears, before the component carrier, is a transfer gear, wherein the transfer gear is a hollow gear for coupling with a proximate gear of the plurality of gears; wherein the transfer gear includes a guide way extending in a rotational direction of the transfer gear with a slope along the guide way, whereby the component carrier is coupled with the guide way by resting means, so that the component carrier is displaced in a linear direction by a rotational movement of the transfer gear due to the slope of the guide way, and whereby all of the plurality of gears overlap with a projection of the transfer gear in the linear direction, excluding a first gear that is directly coupled to an output shaft of the motor.
