PURPOSE:To absorb vibration and noise of a motorfan and simplify the mounting of the motor to the case of the air heating machine by a method wherein the fan-driving motor is attached to the motor mounting rest of elastic body and, thereafter, the motor mounting rest is attached to the case of the air heating machine. CONSTITUTION:The case 1 of an air heating machine is provided with a hole 101, having a diameter slightly smaller than the same of a motor mounting rest 7, at the bottom thereof while the inner periphery of the hole 101 is provided with a recess 102 corresponding to the protuberance 707 of the motor mounting rest and the same rest 7 is fixed to the case 1 by engaging the protuberance 707 with the recess 102. The fan-driving motor 3 generates vibration and noise upon conduction and rotation, however, the motor mounting rest 7 of elastic body absorbs the vibration and noise of the same motor 3 by the internal loss thereof and, therefore, the vibration and noise of the case 1 for the air heating machine may be restricted. |
