Abstract
A pencil type vibration wave driven motor includes a vibration member for generating a vibration wave upon energization of a piezo-electric element. The motor further has a compression member for pressing the rotor against the vibration member. The compression member is arranged between the rotor and an output member engaged with the rotor. The output member is supported by a supporting portion provided with the vibration member through a bearing. In this manner, a compression force of the compression member is applied between the rotor and the vibration member without being reduced.
