Abstract
A thermo-welding device used for a thermoplastic resin molded goods is provided to drastically reduce cooling time and increase productivity. The device is used with a welding boss () formed on the molded goods () made of thermoplastic resin inserted into a fixing holeformed on the fixed object (). A tip section of the welding boss () projecting out from the fixing holeis heated and fused to form an extended portion () outside the fixed object () to apply to the welding boss () of a molded good () in the thermo-welding device used for fixing the fixed object () to the molded good. In a portion of the periphery of a heating element having in a tip section thereof an applying sideto heat and fuse the welding boss, a slitis provided to exhaust air after the air cools the inside of the heating element. In addition, on a pipefor supplying cooling air to the inside of this heating elementare formed a lengthwise holefor blowing air onto the back of the applying sideof the heating elementand a widthwise holefor blowing air onto the internal surface of the heating elementin the backward of the lengthwise hole. The widthwise holeis located in a shifted position at an angle of not facing to said slit
