Bonding method for resin part

Abstract

Abstract PURPOSE:To hold and bond a projected part provided at a joint surface of one resin part into a recess provided at a joint surface of the other resin part, by a method wherein the projected part is placed into the recess, and the joint surfaces of the two resin parts are melted or softened in a melt-bonding operation. CONSTITUTION:One resin part 10 of the two resin parts has an elongate shape and is provided with the projected part 12 along the longitudinal direction at the joint surface 11 on the lower side thereof. The other resin part 14 has an elongate shape and is provided with a groove 16 along the longitudinal direction at the joint surface 15. When the resin parts 10, 14 are relatively reciprocated in the longitudinal direction of the groove 16 while bringing the tip part of the projected part 12 and the bottom surface of the groove 16 into pressure contact with each other, a melted or softened material 22 is spread under pressure in the groove 16 to fill up a lower part of the interior of the groove 16, and the resin part 14 is also melted or softened at a joint part 18. Accordingly, the melted material 22 of the tip part of the projected part 12 flows upwards, while an inlet part 24 of the groove 16 flows downwards, and the both are bonded to each other.
