Patent ID: 7952258

Claim:
A vibration-type actuator comprising: a vibrating body adapted to generate a bending vibration; a driven body adapted to be driven by the bending vibration generated in said vibrating body; and a contact member having a protruding portion fixed to said vibrating body via a plurality of fixing portions and adapted to be in contact with said driven body, wherein said contact member further includes converting portions each disposed between said protruding portion and one of said plurality of fixing portions, wherein said converting portions each have a portion thereof extending obliquely relative to a contact surface provided in said protruding portion for contact with said driven body and extending away from the contact surface in a direction opposite of a protruding direction of said protruding portion, wherein said converting portions are adapted to convert a change in relative distance in a first direction between the plurality of fixing portions caused by deformation of said vibrating body into a displacement in a second direction, which is perpendicular to the first direction, wherein said protruding portion is adapted to be deformed by the distance change between the plurality of fixing portions along the first direction, wherein deforming the protruding portion displaces the contact surface in one direction along the second direction while deforming the converting portions displaces the contact surface in a direction opposite to the one direction along the second direction, wherein said protruding portion is adapted to be deformed by the distance change between the plurality of fixing portions along the first direction, and wherein deforming the protruding portion displaces the contact surface in one direction along the second direction, while deforming the converting portions displaces the contact surface in a direction opposite to the one direction along the second direction.
