ABSTRACT:
A method of fusion bonding of a mark plate places a mark plate, having a heat-melt portion formed on at least a part of a front surface-outer peripheral portion, a side surface and a back surface-outer peripheral portion, the heat-melt portion being made of a thermoplastic resin 6, into a recess portion provided on a surface of a wall plate. A peripheral portion of the mark plate is heated to a temperature not lower than the melting point of the thermoplastic resin from the front surface side of the wall plate by a front surface side heater, e.g. a heating platen 7, while heating the peripheral portion of the mark plate to a temperature not higher than the melting point of the wall plate from the back surface side of the wall plate by a back surface side heater, e.g. another heating platen. Due to this Owing to this method, the mark plate can be fused to have a sufficient depth of fused portion within a shorter period of time, the wall plate of the basket body can be prevented from experiencing the occurrence of thermal strain, and the mark plate can be fusion bonded to the wall plate with a sufficient bonding strength.
