[Effect of idea]

According to the caster and adjuster leg cover for a desk, etc. of the present invention as described above, and the caster and adjuster using the leg cover,
By attaching a common leg cover to the legs of a desk or the like and installing a caster member or an adjuster member in the parts storage space of the leg cover, a lifter or adjuster can be easily configured.

In addition, the parts housing space of the leg cover is made integral with the trochanter housing, bearing, and ground plate housing so that they communicate with each other inside the main body, making it easy to manufacture and strong. Since the support member and the adjuster member can be attached, each member can be attached to the most stable position for support.

In addition, in addition to attaching the same caster member or adjuster member to the leg covers attached to the front and rear of the leg, we also attach a caster member to the rear leg cover for convenience when moving the desk, etc. It is possible to construct a caster by attaching an adjuster member to the front leg cover, and furthermore, by constructing a caster in the same manner as described above on the front and rear of one leg, and attaching an adjuster star to the front and rear of the other leg. You can also configure it, and the choice is free.

Then, the trochanter is accommodated in the trochanter accommodating portion of the parts accommodating space of the leg cover, and the supporting shafts protruding from both sides of the center of the trochanter are abutted and accommodated in the bearing portion from below, and the mounting plate is inserted into the opening. Since the lower end of the trochanter is installed with the lower end exposed, it is possible to restrict the vertical movement of the support shaft and make it rotatable, and not only can the caster be constructed extremely easily, but also the mounting plate allows the lower end of the trochanter to be exposed. The extra space in the open parts storage space can be closed off, giving an excellent appearance.

Furthermore, by simply screwing the upper part of the screw shaft of the adjuster member inserted into the trochanter accommodating part and opening of the parts storage space of the leg cover into the screw hole for the adjuster which is opened downward on the lower surface of the leg, it is extremely easy to use. The adjuster star can be easily configured, and when the screw shaft is rotated and raised to its highest position, the ground plate provided at the lower end of the screw shaft can be accommodated in the ground plate housing part of the parts housing space. It is possible to set a long adjustment stroke when adjusting the height of a desk, etc., and the screw shaft cannot be seen directly from the outside when the upper part of the ground plate is housed in the ground plate housing part, so the appearance is excellent.
