Centralized unlocking operation device

A centralized unlocking operation device comprising a fixed cylinder body (14), a rotor (15) that is inserted into the cylinder body (14) so as to be capable of pivoting between a neutral position and first and second operating positions set on opposite sides of the neutral position in response to a pivoting operation by a legitimate mechanical key (11), a spring (32) that urges the rotor (15) toward the neutral position, a first operating arm (33) that pivots together with the rotor (15) so as to unlock a first locking mechanism (12) when the rotor (15) is pivoted from the neutral position to the first operating position side and that remains at rest when the rotor (15) is pivoted from the neutral position to the second operating position side, and a second operating arm (34) that pivots together with the rotor (15) so as to unlock a second locking mechanism (13) when the rotor (15) is pivoted from the neutral position to the second operating position side and that remains at rest when the rotor (15) is pivoted from the neutral position to the first operating position side, characterized in that the first operating arm (33) is provided with a first pressure-receiving part (35), the second operating arm (34) is provided with a second pressure-receiving part (36), a first pressing face (38) that abuts against and imposes a pressing force on the first pressure-receiving part (35) when the rotor (15) is pivoted from the neutral position to the first operating position side and a second pressing face (39) that abuts against and imposes a pressing force on the second pressure-receiving part (36) when the rotor (15) is pivoted from the neutral position to the second operating position side are formed on a cam part (37) provided on the rotor (15) so as to have a shape that avoids abutment against the second pressure-receiving part (36) when the rotor (15) is pivoted from the neutral position to the first operating position side and avoids abutment against the first pressure-receiving part (35) when the rotor (15) is pivoted from the neutral position to the second operating position side, the spring (32) is provided between the first and second operating arms (33, 34) so as to urge the first and second operating arms (33, 34) in a direction in which the first pressure-receiving part (35) abuts against the first pressing face (38) and the second pressure-receiving part (36) abuts against the second pressing face (39), and the cylinder body (14) is provided with a first restricting part (55) that abuts against the first pressure-receiving part (35) from the same side as the first pressing face (38) when the rotor (15) is at the neutral position and a second restricting part (56) that abuts against the second pressure-receiving part (36) from the same side as the second pressing face (39) when the rotor (15) is at the neutral position.
