PROBLEM TO BE SOLVED: To provide a weight sorting apparatus preventing percussive noises from generating and not sucking dusts into a solenoid device. SOLUTION: The weight sorting apparatus is constituted as follows. A solenoid 30 is provided at the lateral part of a conveyer 11. Bellows 31, 32 are juncturally provided at the top and the bottom of the solenoid 30. A lever 36 which tilts the tray 15 by an action of a plunger 33 provided at the solenoid 30 is juncturally provided. The solenoid device is provided which acts in such a manner that while the bottom bellows 32 is deflated as the plunger 30 ascends to transfer the inner air into the top bellows 31 having an opening 38 through the plunger 33, the air is leaked from the opening 38 as the bellows 31 is inflated, and the air is leaked from the opening 38 while the top bellows 31 is deflated as the plunger 33 descends so as to transfer the inner air into the bellows 32 through the plunger 33.
