Abstract: 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.

Abstract: The present invention is to provide a vehicle door switch that is capable of adjusting the amount of movement made by a rod with ease and a method for attaching a vehicle door switch. A vehicle door switch includes a rod configured to move as a door is closed, a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more, and a limiting unit configured to limit the amount of movement made by the rod within a range where the detecting unit outputs the detection signal.

Abstract: A door driving device includes a driving unit driving a door that opens and closes an entrance of a vehicle having a door case, and a control unit controlling the driving unit such that the door moves with a discontinuous acceleration during a period from when the door starts to open to when the door moves at a constant speed in an opening direction in which the door is retracted into the door case.
