PROBLEM TO BE SOLVED: To provide a convergence correcting mechanism that securely corrects convergence by a simple constitution so as to observe a proximate object scene through binoculars.SOLUTION: A plane substrate 1 is provided with a pair of guide holes 4 and 5 which guide the movement of a pair of left and right objective lens frames 2 and 3. Those guide holes 4 and 5 have inclined portions 4b and 5b which are narrowed down at a mutual interval toward one end side so as to guide the objective lens frames in mutual approaching directions as the objective lens frames 2 and 3 are moved toward a proximate object scene side, and the objective lens frames 2 and 3 are coupled to a drive body 16 which moves the objective lens frames 2 and 3 along optical axes on one surface side of the plane substrate 1 to be displaced in directions perpendicular to the optical axes where the drive body 16 is moved forward and backward along the optical axes in accordance with the rotation of a rotary dial 17 provided at the same surface side of the plane substrate 1. |
