<p>The present invention relates to a cleaner, and more particularly, the technical aim of the invention is to provide a clutch which is inexpensive and has superior performance, a linear motion device which can move linearly in a stable manner and which uses a linear motion guide to reduce manufacturing costs, and a cleaner comprising the clutch and linear motion device. To this end, the clutch of the present invention comprises: a cylindrical driving device rotating by means of the rotating force provided by a power source; a cylindrical insertion device which tightly contacts the inner surface of the driving device and which rotates together with the driving device; a rotary shaft which is coupled to the center of rotation of the insertion device and which rotates in conjunction with the insertion device; and an elastic device which is inserted onto the inner surface of the driving device and outer surface of the insertion device, and which delivers the rotating force of the driving device to the insertion device so as to rotate the rotary shaft.</p> |
