PROBLEM TO BE SOLVED: To provide a both shaft letting-out mechanism, wherein a number of parts is small, and the manufacturing cost can be reduced, and provide also a container having the both shaft letting-out mechanism. SOLUTION: This both shaft letting-out type bar-form material container 100 is equipped with an intermediate cylinder 105 having a female thread 133 on the internal hole, end cylinders 101 and 107, which are rotatably connected to both ends of the intermediate cylinder 105, respectively. Also, in the intermediate cylinder 105 and the end cylinders 101 and 107, a pushing rod 103, which advances/retreats in the axial direction, is provided. The pushing rod 103 has a male thread 121, which is screwed with the female thread 133. At the same time, the pushing rod 103 has a chuck 117 for the holding of the bar-form material on both end sections. A synchronous engaging section (a bat 119 and a synchronous engaging groove 113) is provided between the pushing rod 103 and respective end cylinders 101 and 107. Also, the synchronous engaging section may be provided on the intermediate cylinder side, and the female thread may be provided on the end cylinder sides. |
