ELECTRIC RAZOR WITH COMPACT POWER TRANSMISSION DEVICE AND IMPROVED POWER TRANSMISSION EFFICIENCY

摘要

PURPOSE: An electric razor is provided to compact the structure of a power transmission device from a motor to an inner blade, to improve power transmission efficiency, and to reduce the cost of production by removing time and labor for developing a power transmission device. CONSTITUTION: A motor(31) and a speed-reducing power transmission device(D) are unified to a power module(M) to compact the structure from the motor to an inner blade(15). The power reduced by the speed-reducing power transmission device is transmitted to the inner blade over another power transmission device. The speed-reducing power transmission device minimizes the engaged part of a gear and suppresses the generation of noise.
