PROBLEM TO BE SOLVED: To provide a convenient vacuum cleaner at a low cost by ensuring airtightness without increasing the number of parts and the manpower of assembling for the keeping of sucking performance and the ensuring of vibration control. SOLUTION: This vacuum cleaner comprises an electric blower 3 for generating sucking wind built therein, and a support body 7 cylindrically formed by extrusion-molding materials differed in hardness to integrate the both, cutting the resulting body in a prescribed length, and fixing both ends thereof together is mounted on the circumference of the electric blower 3. The airtightness and damping property can be improved by forming the support body of two materials 7a and 7b differed in hardness, and the airtightness can be enhanced to improve the sucking without increasing the number of part items and the manpower by integrally constituting in the extrusion molding. Accordingly, the effect of preventing the vibration of the electric blower 3 from propagating to a cleaner body 4 through the support body 7 can be enhanced to reduce noise.
