Binoculars. First and second posts are movably disposed in first and second guide slots respectively. A first resilient member is disposed between a first abutting surface and a cover, and the first post slides in the first guide slot facilitating a first barrel to move perpendicular to a first optical axis thereof. Similarly, a second resilient member is disposed between a second abutting surface and the cover, and the second post slides in the second guide slot, facilitating the second barrel to move perpendicular to a second optical axis thereof.
