In order to achieve the above object, the side leg structure of the desk or the like of the present invention is arranged on at least one side of the desk or the like to support the top plate. A side leg structure for a desk or the like, in which a lower horizontal leg rod facing the front-rear direction and an upper horizontal support rod are mounted by sandwiching the rear strut and the intermediate strut at the rear end and the intermediate portion therebetween, A rectangular leg frame is formed, and a fitting groove that faces up and down is formed on at least the front surface of the rear column and the rear surface of the intermediate column that are opposed to each other in the front and rear in the frame, and a space portion in the frame is formed. To the front and rear edges of the side plate that closes, fit a holding member whose left and right dimensions are substantially equal to the groove width of the fitting groove,
A side plate is attached to the inside of the leg frame by slidably fitting the holding member in the fitting groove. According to the side leg structure having the above-described configuration, the holding member having substantially the same size as the groove width into which the side plate is fitted is slidably fitted to the front and rear edges of the side plate that closes the space in the leg frame. By fitting, even if the side plate and the fitting groove have different dimensions, the side plate can be mounted in the leg frame without rattling.

In the above-mentioned side leg structure, the side plate is made of a metal plate, and the base portion is provided with a frame-like flange at the inner end edge of the bulging portion which is bulged outward with the central portion opened, and the bulging portion. It is preferably constituted by a punching plate fixed to the outer surface. With this configuration, even if the side plate is made of sheet metal, the strength is high, and therefore, the side plate is not bent in the thickness direction and is not dented.

In the above side leg structure, it is preferable that a plurality of cutout grooves are formed at the front and rear edges of the side plate, and the holding member is fitted into the cutout grooves. With this configuration, even if the vertical dimension of the holding member is short, it does not vertically shift when being inserted into or removed from the fitting groove.
