PROBLEM TO BE SOLVED: To solve problems for example, in a carriage having a selection tray, in a state that a central part of lateral width has a support shaft, and a carriage boss for being fitted and supported in a state it is laterally rotatable around the support shaft is provided, a rotation state of the carriage boss to the support shaft is easily changed, and correct measurement by a load cell is difficult. ! SOLUTION: The selection tray conveyor is configured so that: an annular recess part 10 with predetermined width is formed on a boss hole 20 inner peripheral surface of a bearing width central part or on four peripheral surfaces of a support shaft on a carriage boss part 9 for being supported to the support shaft 4 in a laterally rotatable state, and a front and rear both ends of the annular recess part 10 have respectively a bearing surface 11 narrower than width of the annular recess part 10. !
