Container screening device

A container screening device comprising:

• a star wheel which is arranged on or above a conveyance surface on which containers are conveyed and which has an outer periphery formed with plural housing portions configured to house the containers;
• a rotation shaft configured to rotate the star wheel;
• a bearing portion rotatably supporting the rotation shaft;
• communication passages which extend through interiors of the star wheel and the rotation shaft and which communicate with the rotation shaft and the housing portions;
• and
• a container suction force generation member fixed to a periphery of the rotation shaft and configured to generate suction force in the communication passages to suck the containers to the housing portions,
• wherein container suction force generation members are provided to overlap each other in an axial direction of the rotation shaft.
