(3) Operation of Centrifuge 1 Hereinafter, the operation of the centrifuge 1 will be described. First, the user of the centrifuge 1 attaches the storage container 60 to the rotating body 32 of the rotating unit 30. This is performed by inserting the main body portion 62 from the second end portion 62b side into the first end portion 32a where the rotating body 32 is opened.

  Here, the rotating body 32 is provided with a receiving portion 33 at a location corresponding to the contact portion 66 provided in the storage container 60. The width w1 of the opening 33a of the receiving portion 33 is formed wider than the width w2 of the contact portion 66 (see FIG. 4). Thus, the user can insert the contact portion 66 into the receiving portion 33 when the storage container 60 is mounted on the rotating body 32.

  In the state where the storage container 60 is mounted on the rotation body 32, the support portion 32 c of the rotation body 32 and the closing portion 64 of the storage container 60 face each other.

The two end portions 62b) coincide with each other.

  Subsequently, the centrifuge 1 starts operation according to the user's instruction or the like in order to process the material M to be processed, and the drive source 51 of the drive unit 50 applies a rotational force to the rotary shaft 10. Thereby, the storage container 60 rotates around the rotation axis L2 while revolving around the rotation axis L1.

  Here, a relative rotational force with respect to the rotation body 32 around the rotation axis L2 is applied to the storage container 60. The relative rotation direction varies depending on the rotation direction around the rotation axis L2 of the storage container 60, acceleration and deceleration conditions, and the like.

  As shown in FIG. 5, when the relative rotation direction is a right rotation, the first contact surface 66 a of the contact portion 66 contacts the first inclined surface 33 b of the receiving portion 33. The first contact surface 66a is pressed against the first inclined surface 33b.

  Here, in a state where the storage container 60 is mounted on the rotating body 32, the first inclined surface 33b extends to the second end 32b side of the rotating body 32 as compared to the first contact surface 66a. And it is comprised as the above inclined surfaces. As a result, a force in the direction of the second end 32b of the rotating body 32 is applied to the first contact surface 66a. As described above, the storage container 60 is in a state where a force is applied in a direction in which it is pressed against the support portion 32 c of the rotating body 32 during operation of the centrifuge 1, and is fixed to the rotating body 32.

  Further, when the relative rotation direction is counterclockwise as shown in FIG. 6, the second contact surface 66 b of the contact portion 66 contacts the second inclined surface 33 c of the receiving portion 33. Then, the second contact surface 66b is pressed against the second inclined surface 33c.

  Here, in a state where the storage container 60 is mounted on the rotation body 32, the second inclined surface 33c extends to the second end portion 32b side of the rotation body 32 as compared to the second contact surface 66b. And it is comprised as the above inclined surfaces. As a result, a force in the direction of the second end 32b of the rotating body 32 is applied to the second contact surface 66b. As described above, the storage container 60 is in a state where a force is applied in a direction in which it is pressed against the support portion 32 c of the rotating body 32 during operation of the centrifuge 1, and is fixed to the rotating body 32.

As a result, the width w4 of the contact portion 166 is wider than the width w2 of the contact portion 66. Further, the receiving portion 133 is formed such that the width w3 of the opening 133a is wider than the width w4 of the abutting portion 166 so that the abutting portion 166 can be inserted.

  In the centrifuge 1, the first contact surface 66a in the contact portion 66 is omitted when the relative rotation of the storage container 60 with respect to the rotating body 32 during operation is only substantially left rotation. The two contact surfaces 66b may be the first contact surface. In this case, in the centrifuge 1, the first inclined surface 33b in the receiving portion 33 is omitted, and the second inclined surface 33c is the first inclined surface.

(5-3) Modification 3
In the centrifuge 1, as shown in FIG. 9, the contact portion 66 can be changed to a contact portion 366.

  The contact portion 366 includes a contact surface 366 a that can contact the first inclined surface 33 b and the second inclined surface 33 c of the receiving portion 33. The contact portion 366 is formed such that its width w7 is narrower than the width W1 of the receiving portion 33.

  The contact surface 366a serves as both the first contact surface and the second contact surface. The contact surface 366a protrudes from the outer surface of the main body portion 62 in the radial direction of the main body portion 62 and is formed in a circumferential surface shape. The contact surface 366a is not limited to being formed in a circumferential surface shape, and may be formed in, for example, an elliptical circumferential surface shape.

  In the centrifuge 1, the contact surface 366 a contacts the first inclined surface 33 b of the receiving portion 33 when the relative rotation direction of the storage container 60 with respect to the rotating body 32 during the operation is clockwise rotation. Then, the contact surface 366a is pressed against the first inclined surface 33b.

  In the centrifuge 1, when the relative rotation direction of the storage container 60 with respect to the rotation body 32 during operation is counterclockwise, the contact surface 366 a contacts the second inclined surface 33 c of the receiving portion 33. The contact surface 366a is pressed against the second inclined surface 33c.

  Here, in a state where the storage container 60 is mounted on the rotating body 32, the first inclined surface 33b and the second inclined surface 33c are compared with the end portion on the second end portion 32b side of the contact surface 366a. It extends to the second end 32b side.

  Thereby, a force in the direction of the second end portion 32b is applied to the contact surface 366a. As described above, the storage container 60 is in a state where a force is applied in a direction in which it is pressed against the support portion 32 c of the rotating body 32 during operation of the centrifuge 1, and is fixed to the rotating body 32.
