<Problem> It is an object of the present invention to provide a timing hopper that inhibits the occurrence of the problem that articles end up getting stuck inside the timing hopper and are not normally discharged. <Solution> A timing hopper 9 includes a first member 91, a second member 92, and a gate 9a. The first member 91 has a first opening 91a to which articles A are input. The second member 92 has a second opening 92a from which the articles A are discharged. The gate 9a opens and closes the second opening 92a. The first member 91 has a first side wall 91b and a second side wall 91c. The second side wall 91c opposes the first side wall 91b. The second member 92 has a third side wall 92b and a fourth side wall 92c. The third side wall 92b is continuously connected to the first side wall 91b. The fourth side wall 92c opposes the third side wall 92b and is continuously connected to the second side wall 91c. The height position where the first side wall 91b and the third side wall 92b are interconnected is different from the height position where the second side wall 91c and the fourth side wall 92c are interconnected.
