To make a coupling or uncoupling of a driving bar to a sliding unit simple.
A driving unit 25 is capable to couple with a driving bar 32 of a rectilineal driving unit 30 via a coupling part 40. Sliding unit housings 21 and 22 are equipped with a holding unit 28 to accommodate the rectilineal driving unit 30. The coupling part 40 is so constructed that it automatically couples when the rectilineal driving unit 30 is pushed into the holding part 28 by sliding the driving bar 32 towards the sliding unit 25. At the same time, when the rectilineal driving unit 30 is pulled out from the holding part 28, a coupling of the coupling part 40 is automatically released. The other coupling end of the coupling part 40 has a clicking device and is kept opened until the clicks grasp the other coupling end of the other coupling part configurationally in accordance with a guiding face, when coupled.
