<p>The present invention relates to a coupling device of a footrest. The coupling device of a footrest has a footrest support (200) having a tilted trapezoidal shape to maintain a predetermined tilt having a predetermined space in an upper plate of the footrest (100) made of wood and a lower portion thereof. The coupling device includes a coupling member (300) which can be hinged to fasten the upper plate of the footrest (100) and the footrest support (200) and is formed to have a T-shape. The coupling device includes a bolt hole (322) to be coupled to a left side horizontal plate (310) and a right side horizontal plate (320) which are horizontal plates coupled to the upper plate (100) by the bolt. The coupling device of a footrest has a tilted guide hole (330) on a vertical plate (330) coupled to a support plate of the footrest to be coupled by the bolt (332).</p> |
