A protecting hood assembly for use in a motor-driven hand tool such as grinder or circular saw. The assembly includes a hood having a pair of openings, each being formed with a narrowing portion of a squared cross-section and a widened portion forming a slot, a pair of vertically positioned supporting members each having a longitudinal slit and a couple of bolts having each a peripheral portion inserted into said slit and said opening. The widened portion of the opening receiving the bolt is formed with a size in a horizontal direction being larger that a diameter of the peripheral portion of the bolt and a size in a vertical direction being smaller that said diameter to facilitate the installation of the bolt into the hood opening upon assembling and to provide a reliable clamping of said bolt in assembly after insertion thereof.
