Abstract

The tripod attachment for attaching a pair of binoculars to a tripod has a friction force producing member providing friction force to hold the pair of binoculars at any desired position with respect to an attachment body when fastening a screw member to the pivot of the pair of binoculars and at the same time to allow the entire pair of binoculars to rotate around the screw member only when certain external force is applied to the pair of binoculars. Therefore, the horizontal correction of the pair of binoculars can be performed only by rotating the pair of binoculars; thus, the tripod attachment can be easily handled. When performing the horizontal correction of the pair of binoculars with the tripod attachment, external rotating force is applied to the pair of binoculars so that the entire pair of binoculars rotates around the screw member against the friction force. Then, application of rotating force to the pair of binoculars is stopped at the position where the telescopes constituting the pair of binoculars are horizontally arranged, and the pair of binoculars is held at the position by the friction force.
