PURPOSE:To make the mounting and dismounting of a heat pipe very easy and minimize the resistance to the contact heat which is generated at the insertion and attachment section by forming a cap which seals and closes the end of a container in a sturdy structure which withstands a powerful spiral rotation torque and external force for insertion and pulling-out and forming on the end face of the cap a structure of female type for insertion and pulling-out by spiral rotation. CONSTITUTION:For example, on a cap 2 both a structure section 3 of insertion and pulling-out by spiral rotation and a working liquid sealing section 4 of non-projection type are provided simultaneously. In the working liquid sealing section 4 of non- projection type a small diameter pipe 4-4 for sealing is crushed by a pin for crushing which is pressed in from a side hole 4-2 for crushing in a throughhole provided in the cap to seal the working liquid in the state that a crushing section 4-1 is incorporated in the cap. A soldering junction 4-3 improves the reliability of crushing in the crushing section 4-1. Because the projection section in the conventional device is not left, it is possible to carry out easily the spiral rotation work. Further, the heat pipe has no projection section entirely so that it is possible to make the effective length of the heat pipe when it is inserted longer.
