A hair clipper has a blade block, which includes a fixed blade, a movable blade overlapped with the fixed blade to make sliding contact with the fixed blade, a pressing spring applying a pressing load to maintain a uniform contact pressure between the fixed blade and the movable blade, and a blade base for receiving and retaining the fixed blade and the movable blade and the pressing spring. The blade base has a blade holder retaining the fixed blade and the movable blade and a blade cover attached to the blade holder to cover the fixed blade and the movable blade. Further, the blade holder has a primary retainer member holding end portions of the pressing spring and the blade cover has a secondary retainer member pressing the end portions of the pressing spring in a direction in which the pressing spring is retained by the primary retainer member.
