PROBLEM TO BE SOLVED: To provide a core assembling device capable of holding a core on a branch pipe inner surface without using any dedicated assembling and pushing-in tool around a branch pipe, and easily and surely fitting the core in a bored hole only by applying a pushing-in force toward the bored hole to the core, and a core fitting method using the same.SOLUTION: A case 2 communicating with a bored hole Q bored in a fluid pipe 1 and covering the outer periphery of the fluid pipe 1 in a sealed state, includes a branch pipe 12 attached to the fluid pipe 1, and a valve cap 3 for housing a valve element 5 to be connected to the branch pipe 12 in a sealed state. A core 40 is made of a member movable toward the bored hole Q by pushing-in force toward the hole Q and reduced in diameter, and held in the inner peripheral surface of the branch pipe 12. |
