PURPOSE:To enable to easily cope with the change of height by one and the same appliance by structure wherein a receiving lid is divided into a lower supporting part and an upper mounting part, both of which are slidably fitted to each other so as to steplessly cope with the change of height. CONSTITUTION:A receiving lid is divided into a lower supporting part 2 and an upper mounting part 3, both of which are fitted to each other by means of guides 12 and 13, on which apertures 6 and 7 are provided respectively. The receiving lid consisting in anchoring the lower supporting part 2 and the upper mounting part 3 by means of movable pins 5, pivots about the lower ends of the receiving lid or holes 10, into which the supporting fittings 4 provided on a main body 11. The upper end of the receiving lid is mounted to the main body by fitting claws 9 to mounting holes 8 provided on the main body 11. At this time, the relative position between the lower supporting part 2 and the upper mounting part 3 is changed through the movable pin 5 from the distance between the point (a) of the aperture 6 and the point (c) of the aperture 7 to the maximum distance obtained by summing up the distance between the points (a) and (b) and that between the points (c) and (d). The change of said relative position is done by mutually sliding the guides 12 and 13. In such a manner as mentioned above, even when the height of the main body 11 changes, said change can be coped with by steplessly and freely moving the lower supporting part 2 and the upper mounting part 3 in their maximum movable ranges. |
