Abstract
A vibration transmitter includes: a proximal end extending portion; a supported portion; a distal end extending portion; a first relay unit provided between the supported portion and the proximal end extending portion; and a second relay unit provided between the supported portion and the distal end extending portion. The second relay unit includes a horn that is constructed such that an outer diameter at a position continuously adjacent to the supported portion is larger than: (i) an outer diameter of the first relay unit at a position continuously adjacent to the supported portion, and (ii) the outer diameter of the distal end extending portion. The horn expands amplitude of vibration output from a distal end of the distal end extending portion to be larger than a maximum amplitude at an antinode of vibration in the first relay unit or the proximal end extending portion.
