軸受の外周よりわずかに大きい多面体リング部を
形成して成る軸受保持機構。 The electric tool is driven by a commutator motor, and includes two bearings that support both ends of an armature of the commutator motor, and a housing that holds the bearings, and an outer peripheral portion of the bearing on the commutator side and a housing that holds the bearings. In the bearing anti-vibration holding mechanism that elastically holds the bearing by disposing an elastic body between the bearing boxes of the housing that holds the bearing, the electric motor is placed between the commutator of the bearing box and the elastic body. A bearing holding mechanism formed by forming a polyhedral ring portion on the child shaft, the diameter of the inscribed circle being slightly larger than the outer circumference of the bearing.
