A plurality of extensible support bars 44 projecting from the lower case 2 side to the upper case 3 side of a main body case 5 are provided. An electric blowing part 11 is placed on the support bars 44. By covering and attaching the upper case 3 onto the lower case 2, the electric blowing part 11 is sandwiched between the support wheels 45 and the support bars 44. The electric blowing part 11 can be easily fitted into a blowing chamber 6, and the manuf acturability is improved. |
