The present invention relates to a cleaner. In particular, the present invention fulfills the technical task of providing a clutch with a low-cost and high performance; a linear moving apparatus capable of saving production costs as compared with using a linear motion guide, while being capable of stable linear movement; and a cleaner including the same. For this, the clutch according to the present invention comprises: a cylinder-shaped driving apparatus rotated by torque provided from a power source; a cylinder-shaped insertion apparatus rotated together with the driving mechanism while adhering to an inner peripheral surface of the driving apparatus; a rotary shaft rotated as one with the insertion apparatus by being fastened to a rotation center of the insertion apparatus; and an elastic apparatus inserted on an inner peripheral surface of the driving apparatus and an outer peripheral surface of the insertion apparatus to transmit torque of the driving apparatus to the insertion apparatus for rotation of the rotary shaft. |
