摘要： An overhead transport vehicle includes a container accommodation portion sandwiched by a pair of cover portions in a front-and-rear direction in a traveling direction and configured to hold a cassette in a state in which a lid faces in a width direction intersecting the traveling direction and a vertical direction; and a lid-fall prevention member on the cover portion to prevent the lid that has come off from the cassette held in the container accommodation portion from falling. The lid-fall prevention member includes a lower support portion extending along the width direction below the cassette and partially protruding from the lid in a planar view seen from the vertical direction, and a front support portion standing upright in the vertical direction from the lower support portion so as to face at least a portion of the lid. The lower support portion and the front support portion are integrally defined by a unitary structure.

摘要： An overhead transport vehicle includes an elevator including a base and a first support supporting the base to be vertically movable from below in a vertical direction through a vibration isolator. The vibration isolator includes a first biasing portion in contact with both of the support and the base to urge a first body and the base in a direction away from each other, and a second biasing portion at one of the first body and the base to come into contact with both of the first body and the base and urge the first body and the base in a direction away from each other when a load equal to or greater than a predetermined value is applied to the first biasing portion.

摘要： A moving mechanism moves a swing suppression unit in a traveling direction between an advanced position contacting a FOUP and a retracted position away from the FOUP by a drive of a drive unit. A buffer mechanism that allows the swing suppression unit that has been moved to the advanced position by the drive of the drive unit to move to the traveling direction after stopping the drive of the drive unit. The buffer mechanism includes a first coupling portion and a rod-shaped portion coupled to the swing suppression unit to perform a movement of an operation amount in accordance with an amount of movement of the swing suppression unit to a second position direction, a first bias portion that biases the first coupling portion and the rod-shaped portion so that the swing suppression unit presses the FOUP, and a second bias portion that acts on the first coupling portion and the rod-shaped portion when the operation amount of the first coupling portion and the rod-shaped portion is greater than a predetermined amount and that biases the first coupling portion and the rod-shaped portion so that the swing suppression unit presses the FOUP.
