PROBLEM TO BE SOLVED: To provide a combination weighing apparatus capable of improving convenience and durability in view of replacement of a screw member by a user.SOLUTION: The combination weighing apparatus comprises: a main body; a plurality of weighing parts; troughs extending toward the plurality of weighing parts radially from the center of the main body in planar view; screw parts with a spiral shape disposed in the troughs and configured to transfer objects to be weighed in the troughs toward the weighing parts, the screw parts transferring the objects to be weighed by rotating in the troughs; and rotation drive parts configured to rotate the screw parts. An end part of one of the screw part and the rotation drive part has a projection part rotating about the rotation axis defined in the direction of attaching the screw part, and an end part of the other thereof has a grooved cam which the projection part fits into and the fit projection part slides on. After the projection part fits in the grooved cam, the rotation of the screw part causes the projection part to slide on the grooved cam to attach the screw part to the rotation drive part.SELECTED DRAWING: Figure 1 |
