A flow rate adjusting device of the present invention includes a flow channel member and a valve mechanism. The valve mechanism includes a rod, a knob and a lock mechanism. The lock mechanism is switched by the knob moving in the traverse direction between a prohibited state in which the engaging portion is engaged with the to-be-engaged portion so that the rotation of the rod relative to the flow channel member is prohibited via the knob and a permitted state in which the engagement between the engaging portion and the to-be-engaged portion is undone so that the rod is permitted to rotate relative to the flow channel member.
