Abstract
PURPOSE: To maintain a roller in a fixed position and make the operation of collapsing smooth by providing a spring in an intermediate lever and pressing the roller to the oblong groove end part of the inermediate lever.
CONSTITUTION: During protruding and collapsing operations of a lens barrel 2, a roller 41 is constantly held pressed to one end in the oblong groove 42b opened in the plate 42 of an intermediate lever 4 by a spring 45 and pin 44 to maintain a fixed position. Because of this, if the pin 34 positions on the a-a line, the lever compresses the spring 45 and causes the roller 41 to move, but when it exceeds the a-a line, the spring 45 acts in the extending direction, causing the roller 41 to be pressed in the one end direction in the oblong groove 42b thereby subsequently turning the lever 4. Hence, at the time when the lever 4 springs up the pressing lever 8, the right and left positions of the roller 41 are kept constant even on the way of pushing in the lens barrel and since the barrel is not exerted with the pressing forces differing with right and left, it may be smoothly collapsed.
