Overhead transport system

14:

• An overhead transport system comprising:
• an overhead transport vehicle including a traveling portion to travel along an overhead rail, a gripper to grip an article, and a lateral mover to move the gripper in a lateral direction;
• and
• a support to support the lateral mover in a case where the gripper is moved in the lateral direction by the lateral mover;
• wherein
• the lateral mover includes a slider to slide relative to a transport vehicle body in the lateral direction, a protrusion protruding upward from the slider, and a contact provided at the protrusion and movable in the lateral direction while being in contact with the support when the gripper is moved in the lateral direction by the lateral mover.

17:

• The overhead transport system according to claim 14, wherein
• the contact includes a roller rotatably supported by the protrusion with an axis along a traveling direction of the overhead transport vehicle as a rotation axis;
• and
• the support supports the roller from below.

20:

• The overhead transport system according to claim 19, wherein
• each of the pair of support portions has a plate shape elongated in the lateral direction;
• a tapered surface is provided on an upper surface of an end portion of at least one of the pair of support portions, the tapered surface being inclined downward from a center of the support portion toward an end portion side;
• and
• at least one of the pair of rollers rides on the tapered surface when the gripper is moved in the lateral direction by the lateral mover.

23:

• The overhead transport system according to claim 14, wherein
• the overhead transport vehicle further includes a rotator provided between the lateral mover and the gripper to rotate the gripper about a rotation axis along a vertical direction;
• and
• the contact includes a first contact located to one side of the rotation axis in the lateral direction and a second contact located to the other side of the rotation axis in the lateral direction.

24:

• The overhead transport system according to claim 14, wherein
• the lateral mover includes another slider located above the slider and slidable relative to the transport vehicle body in the lateral direction;
• the slider is slidable relative to another slider in the lateral direction;
• the another slider includes a pair of rails extending in the lateral direction and sandwiching the contact in a traveling direction, the pair of rails being positioned to guide the sliding of the slider, and a connector that connects the pair of rails to each other;
• and
• the connector extends in a traveling direction while passing above the contact and surrounding the contact as viewed in the lateral direction.

25:

• The overhead transport system according to claim 14, wherein
• the support includes a first support located to one side of the overhead transport vehicle in the lateral direction and a second support located to the other side of the overhead transport vehicle in the lateral direction;
• the lateral mover is operable to move the gripper in one direction and the other direction of the lateral direction;
• and
• the contact is movable in the lateral direction while in contact with the first support when the gripper is moved in one direction of the lateral direction by the lateral mover and is movable in the lateral direction while being in contact with the second support when the gripper is moved in the other direction of the lateral direction by the lateral mover.

26:

• The overhead transport system according to claim 14, further comprising:
• a storage shelf including a mount on which the article is mounted;
• wherein
• the support defines the storage shelf.
