PROBLEM TO BE SOLVED: To provide a dust collector of which a filter unit can be renewed by one operator. SOLUTION: An upper chamber 2 and a lower chamber 3 are formed in a casing 1, and a take-out opening 6 with a door 7 is provided on the peripheral wall of the lower chamber 3. Plural communication holes 9 linearly arranged toward the take-out opening 6 are provided on a partition plate 8 between the upper chamber 2 and the lower chamber 3, and a guide rail 11 which is long extended in the arranged direction of the communication holes 9 is equipped under a partition plate 8, and a filter unit 12 is removably supported by the guide rail 11. A tapered face 16 is formed beneath the end of the guide rail 11 located at the back of the easing 1, and the tapered face 16 is supported by a fixed guide-pin 17. The filter unit 12 is set to the guide rail 11 and then the guide rail 11 is forced into the housing 1 so as to be diagonally moved upward by sliding of the tapered surface 16 on the guide pin 17, and the upper surface of a support 26 is put into close contact with the lower surface of the partition plate 8 and the back end part of the guide rail 11 is fixed on the partition plate 8 by clamping of a set bolt 23.
