Patent ID: 6856072

Claim:
A driving mechanism comprising: a base; a first displacement part which has a pair of ends and which can expand and contract between the pair thereof, in which one of the pair is supported by the base; a second displacement part which has a pair of ends and which can expand and contract between the pair thereof, in which one of the pair is supported by the base; and a resultant part which connects the other of the pair of the first displacement part and the other of the pair of the second displacement part to each other, in which the resultant part has a contact part that contacts a body to be driven by the contact part, wherein the contact part can elastically deform in a direction in which the body is driven by the contact part, and material and configuration of the base, of the first displacement part, of the second displacement part, and of the resultant part are selected so that resonant frequency of the resultant part in the direction in which the body is driven is generally equal to resonant frequency of the first displacement part and the second displacement part in a direction perpendicular to the direction in which the body is driven.
