The device includes a fixed portion, a pivoting portion with a holding portion for holding the optical member, a pivot shaft, a driving portion, and a pivot suppressing portion. The pivot suppressing portion has a first magnet at the pivoting portion, and a second magnet at the fixed portion. The first magnet and the second magnet are disposed in such a manner that the same magnetic poles face each other in the pivoting direction. ## Claims ### Claim 1 An optical member driving device, comprising: a fixed portion; a pivoting portion with a holding portion for holding the optical member; a pivot shaft; a driving portion; and a pivot suppressing portion, wherein the pivot suppressing portion comprises a first magnet provided at the pivoting portion, and a second magnet provided at the fixed portion, the first magnet and the second magnet are disposed in such a manner that the same magnetic poles face each other in a pivoting direction. ### Claim 2 (depends on 1) The optical member driving device according to claim 1, wherein one of the first magnet and the second magnet is disposed with respect to the other one of the first magnet and the second magnet, in such a manner that the same magnetic poles face each other from both sides in the pivoting direction. ### Claim 3 (depends on 2) The optical member driving device according to claim 2, wherein one of the first magnet and the second magnet is disposed with respect to the other one of the first magnet and the second magnet, in such a manner that the same magnetic poles face each other from both sides in an extending direction of the pivot shaft. ### Claim 4 (depends on 3) The optical member driving device according to claim 3, wherein one of the first magnet and the second magnet is disposed with respect to the other one of the first magnet and the second magnet, in such a manner that the same magnetic poles face each other from both sides in a predetermined direction inclined relative to both the pivoting direction and the extending direction of the pivot shaft. ### Claim 5 (depends on 4) The optical member driving device according to claim 4, wherein of the first magnet and the second magnet, the magnet arranged on an outer side has a right-angled isosceles triangular prism shape, and a surface corresponding to a bottom of the right-angled isosceles triangular shape faces the magnet arranged on an inner side. ### Claim 6 (depends on 3) The optical member driving device according to claim 3, wherein the first magnet and the second magnet are arranged in the pivoting direction, of the first magnet and the second magnet, the magnet arranged on an inner side and the magnet disposed on an outer side have different lengths in the extending direction of the pivot shaft, and regardless of movement of the pivoting portion in the extending direction of the pivot shaft, the entire shorter magnet faces the longer magnet. ### Claim 7 (depends on 6) The optical member driving device according to claim 6, wherein the magnets arranged on the inner side comprises two magnets in the arrangement direction, the adjacent magnets arranged on the outer side and the magnets arranged on the inner side face each other, respectively. ### Claim 8 (depends on 3) The optical member driving device according to claim 3, wherein the first magnet and the second magnet are arranged in the extending direction of the pivot shaft, of the first magnet and the second magnet, the magnet arranged on an inner side and the magnet disposed on an outer side have different lengths in the pivoting direction, and regardless of movement of the pivoting portion in the pivoting direction, the entire shorter magnet faces the longer magnet. ### Claim 9 (depends on 8) The optical member driving device according to claim 8, wherein the magnets arranged on the inner side comprises two magnets in the arrangement direction, the adjacent magnets arranged on the outer side and the magnets arranged on the inner side face each other, respectively. ### Claim 10 (depends on 1) The optical member driving device according to claim 1, further comprising a coil, wherein the first magnet also serves as a driving magnet that generates a driving force of the pivoting portion together with the coil. ### Claim 11 (depends on 1) A camera device comprising the optical member driving device according to claim 1. ### Claim 12 (depends on 11) An electronic apparatus comprising the camera device according to claim 11.
