ABSTRACT:
The cleaning apparatus for removing foreign substances includes a spacer which is interconnected between a generally planar member and a vibrator, wherein the spacer provides a space for separating the generally planar member from the vibrator. The spacer allows the generally planar member to bend easily. Thus, a large amplitude of vibration can be obtained on the whole of the generally planar member.
