Abstract
A linear driving device includes a slight rapid vibratory movements producing member coupled with one end of a driving shaft which causes said driving shaft to be moved in said an axial direction, a casing for supporting at least either said driving shaft or said slight rapid vibratory movements producing member so that said driving shaft can be moved in said axial direction; and a moving body to be coupled with said driving shaft so that said moving body can be moved in the axial direction. When said moving body moves from one end side toward the other end side of said driving shaft, a part of said moving body which forms the surface facing the other end side opposite to said one end of said moving body may hit against a component which stops said moving body from moving further toward the other end side of said driving shaft.
