A vibration type motor includes first and second vibrators, a friction member configured to contact the first and second vibrators, a pressure member configured to press the first and second vibrators against the friction member, and first and second guide members configured to guide a relative movement between the first and second vibrators and the friction member. The first and second vibrators are spaced in a direction different from a relative movement direction between the first and second vibrators and the friction member. The first and the second guide member are provided between the first vibrator and the second vibrator in a direction different from the relative movement direction. A pressure center of a pressure applied to the first vibrator and the second vibrator by the pressure member is located between the first guide member and the second guide member.
