一対のボールネジと、該ボールネジを回転させるサーボ
モータ（電動機）とから構成されたものである。That is, the tube expanding device described in the above publication has a base and a main body as main structures, and a mandrel block as a reciprocating body provided with a mandrel, a column inserted into the mandrel block, and a mandrel block attached to the mandrel block. It is composed of a pair of ball screws formed with a predetermined threaded portion to be screwed into the nut and a servomotor (electric motor) for rotating the ball screws.
（考案が解決しようとする課題） しかしながら、上記構成からなる拡管装置に於いては下
記の様な問題点があった。(Problems to be Solved by the Invention) However, the tube expanding device configured as described above has the following problems.
即ち、上記構成からなる拡管装置は、一対のボールネジ
を電動機で回転させてマンドレルを具備した往復作動体

よって、必ずボールネジの両端側にベアリング等のボー
ルネジ支持体を複数必要とするが、通常該ベアリング等
のボールネジ支持体は非常に高価であるばかりか、拡管
装置の構成そのものが非常に複雑となる。Therefore, a plurality of ball screw supports such as bearings are necessarily required at both ends of the ball screw, but usually the ball screw supports such as bearings are very expensive, and the structure itself of the tube expanding device becomes very complicated.
更に、上記構成からなる拡管装置は、ボールネジを回転

By eliminating the protrusion of the electric motor from the tube expanding device, the tube expanding device can be made compact and the installation space can be kept to the minimum necessary. Not only is it possible to reciprocate the reciprocating body without further rotating the ball screw, but it is possible to configure the tube expanding device with a simple structure, and thus it is possible to reduce the manufacturing cost of the tube expanding device. It is an object to provide an extremely excellent tube expanding device.

転を介して該電動機11aと共に往復動自在で、且つ前記
往復作動体７と別個に駆動する点にある。Further, below the reciprocating body 7, a flare portion is provided on the tube 12 expanded by the reciprocating motion of the reciprocating body 7 along the rod-shaped body 5 having the threaded portion 6 for inserting the reciprocating body 7. A flared body (14) provided with an expanding sleeve (13) for forming is provided, and the flared body (14) has the flared body (14).
