Vibration type motor, lens apparatus, and electronic device

An electronic device comprising:

• a vibration type motor;
• and
• an object configured to be driven by the vibration type motor,
• wherein the vibration type motor comprising:
• a vibrator including a piezo element, a contacting portion, and a holding portion, the vibrator being configured to generate a first vibration and a second vibration;
• a friction member configured to make frictional contact with the contacting portion of the vibrator;
• a holding member configured to hold the holding portion of the vibrator;
• and
• a biasing member configured to bias the holding portion of the vibrator to the holding member,
• wherein a condition below is satisfied:
• A3/A1<A4/A2,
• where A1 and A2 are respectively amplitudes of the contacting portion in the first vibration and the second vibration, and A3 and A4 are respectively amplitudes of the holding portion in the first vibration and the second vibration in a state where the vibrator is not held by the holding member.

A vibration type motor comprising:

• a vibrator including a piezo element, a contacting portion, and a holding portion, the vibrator being configured to generate a first vibration and a second vibration;
• a friction member configured to make frictional contact with the contacting portion of the vibrator;
• a holding member configured to hold the holding portion of the vibrator;
• and
• a biasing member configured to bias the holding portion of the vibrator to the holding member,
• wherein the holding portion is provided at a position that is a node of the first vibration and that is not a node of the second vibration.
