Next, by rotating the tubular engagement member 30 slightly, the protrusions 14A to 14C are positioned inside the thick portion 34A, so that the engagement state is locked.

Next, similarly, one end side 20A of the second tubular body 20 is made to face the other end side 30B of the tubular engaging body 30 in which the first tubular body 10 has already been inserted, and each protrusion 24A After aligning the positions of the thin portions 34B with the positions of 24C to 24C, the second tubular body 20 is pushed so as to be inserted into the tubular engaging body 30, and the protrusions 24A to 24C are inserted into the engaging grooves 33. To engage. Next, by rotating the tubular engagement body 30 a little, the protrusions 24A to 24C are positioned inside the thick portion 34A, so that the engagement state is locked.

This makes it possible to easily bring the first and second cylinders 10 and 20 into intimate contact with each other and to remove them from each other only by rotating the cylindrical engaging body 30. Can be detachably held.

Since the first cylinder 10 and the second cylinder 20 are provided with directivity, it is convenient to form them so that their lengths are different from each other. For example, if the length dimension of the first tubular body 10 is set to L1 and the length dimension of the second tubular body 20 is set to L2 (L1 <L2), the first tubular body 10 having a smaller dimension is transformed toward the transformer. It can be used as a guide to say that the input side winding 3 is wound.

Although an example in which three lead wires (one is an intermediate tap) is drawn from each of the input side winding 3 and the output side winding 4 shown in the embodiment of the present text, the number of lead wires is not limited. Can be withdrawn at will.
