an insertion depth of the other end portion of the rod-shaped member is smaller than a depth of the concave portion of the second terminal member, so that an end surface surrounding the concave portion of the second terminal member does not make contact with the rod-shaped member.

3. The transfer apparatus according to claim 1 ,

wherein the rod-shaped member and the first terminal member are fixed to each other by welding.

4. The transfer apparatus according to claim 1 ,

wherein the rod-shaped member and the first terminal member are fixed to each other by a fastening pin.

5. The transfer apparatus according to claim 1 ,

wherein the rod-shaped member makes contact with the second terminal member via a key.

6. The transfer apparatus according to claim 1 ,

wherein the first terminal member and the second terminal member are made of a nonmagnetic material.

7. The transfer apparatus according to claim 1 ,

wherein the cover and the first terminal member are fixed to each other by welding.

8. The transfer apparatus according to claim 1 ,

wherein the cover and the second terminal member are fixed to each other by welding.

9. The transfer apparatus according to claim 1 , further comprising:

a first bearing configured to receive a load of the first terminal member; and

a second bearing configured to receive a load of the second terminal member.

10. The transfer apparatus according to claim 1 , further comprising:

an opposite member configured to face a part of a side surface of the rod-shaped member, the opposite member comprising a magnetic material,

wherein the opposite member is configured to move along the central axis of the rod-shaped member when the driving device rotates the rod-shaped member.

11. A storage apparatus comprising:

a storage housing that stores an article;

a rod-shaped member that comprises a magnetic material;

a cover configured to cover the rod-shaped member, the cover being made of a nonmagnetic material;

a first terminal member configured to allow insertion of one end portion of the rod-shaped member;

a second terminal member configured to allow insertion of another end portion of the rod-shaped member;

an opposite member configured to face a part of a side surface of the rod-shaped member, the opposite member comprising a magnetic material,

a driving device configured to be connected to the first terminal member, rotate the rod-shaped member about a central axis of the rod-shaped member, and change a relative position between the rod-shaped member and the opposite member; and

a contact member configured to move in the storage housing with a change in the relative position between the rod-shaped member and the opposite member and moves the article while making contact with the article,

wherein the rod-shaped member and the first terminal member are fixed to each other,

the cover and the first terminal member are fixed to each other,

the rod-shaped member and the second terminal member are not fixed to each other, and

the cover and the second terminal member are fixed to each other.

12. The storage apparatus according to claim 11 ,

wherein a concave portion configured to allow insertion of the other end portion of the rod-shaped member is provided in the second terminal member, and

an insertion depth of the other end portion of the rod-shaped member is smaller than a depth of the concave portion of the second terminal member, so that an end surface surrounding the concave portion of the second terminal member does not make contact with the rod-shaped member.

13. The storage apparatus according to claim 11 ,

wherein the first terminal member and the second terminal member are made of a nonmagnetic material.

14. The storage apparatus according to claim 11 , further comprising:

a first bearing configured to receive a load of the first terminal member; and

a second bearing configured to receive a load of the second terminal member.

15. The storage apparatus according to claim 11 ,

wherein the driving device is disposed outside the storage housing.

16. The storage apparatus according to claim 11 ,

wherein the rod-shaped member, the opposite member, and the contact member are disposed in the storage housing.

17. The storage apparatus according to claim 11 ,

wherein the storage housing is a temperature-controlled furnace having a temperature-controlled space.
