This is so that the support bar 410 can be detachably coupled to the bottom plate 203 so that the support bar 410 can be separated from the bottom plate 203 or installed on the bottom plate 203 .

The supporting bar 410 is preferably connected to the pair of supporting units 412 in a detachable manner. Here, it can be understood that the support member 430 is coupled to the support unit located at the lower one of the pair of support units 412.

For example, the support unit 412 may have a coupling groove 411 formed at a lower portion thereof and an upwardly extending coupling projection 413 formed at an outer peripheral surface thereof to form a thread, have.

The opening and closing apparatus main body 102 is formed at both ends of the lower portion of the lower portion so as to extend in one end direction at the other end so as to oppose the groove portion 421 and has a fastening hole 461 penetrating in the up and down direction, A supporting plate 460 is formed.

The fastening holes 461 extend from the other end of the support plate 460 in one end direction, and have a 'C' shape when the upper end is viewed from above. Here, the fastening hole 461 can be understood to have the same shape as the groove portion 421.

The supporting part 400 is screwed to the supporting bar 410 so as to be able to move up and down and is moved in the longitudinal direction of the supporting bar 410 in accordance with the rotation of the binding part 410 to bind the supporting bar 410 to the supporting plate 460 470).

The binding member 470 may be formed of a nut or the like having a thread on the inner circumferential surface thereof and is screwed to the support bar 410 so as to be positioned below the support plate 460. Here, it can be understood that the binding member 470 is coupled to the supporting unit located in the upper portion of the pair of supporting units 412. [

The binding member 470 is lifted or lowered according to the rotation to bind or release the upper portion of the support bar 410 to or from the support plate 460.

The fixing means 440 may be formed of a magnet 441 and may be provided on a surface where the connecting bar 420 and the control device body 201 are in contact with each other.

The connection bar 420 can remain attached to the control device body 201 when not in use.

Therefore, the support portion 400 can be made to be in a stable support state with respect to the control device body 201 when the pinion gear 304 is detached from the drive motor 302 due to wear or defects, or the like.
