付構造。 In a case consisting of a case frame consisting of a top, a bottom plate, left and right side plates, and a back plate and having an opening on the front, and a front plate that is detachable from the opening of the case frame, the opening has a peripheral edge. An engaging portion between a flange bent in the depth direction within the housing and the front plate located on the upper side of the opening, and an engaging portion protruding perpendicularly to the flange and in the width direction of the housing on the left and right vertical sides near the lower side of the opening. and a protrusion on the periphery of the front plate,
a bent portion that horizontally faces the flange when attached to the opening; an S-shaped leaf spring that elastically fits into the engagement protrusion; and a portion with a curvature that is approximately the same as the curvature of the fitting portion of the S-shaped leaf spring. and a notch having an opening, the fitting portion of the S-shaped leaf spring being located at a higher position in the direction of the upper side of the front plate than the position of the curvature of the notch when the front plate is removed from the opening. Body front plate mounting structure.
