A centralized unlocking operation device is provided in which a first operating arm pivots in response to a rotor being pivoted from a neutral position in a forward direction, and a second operating arm pivots in response to the rotor being pivoted from the neutral position in a reverse direction, wherein a first pressing face (38) that abuts against and imposes a pressing force on a first pressure-receiving part (35) of the first operating arm (33) 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 a second pressure-receiving part (36) of the second operating arm (34) 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), and 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 and second pressure-receiving parts (35, 36) abut against the first and second pressing faces (38, 39). This enables confirmation of whether or not two operating arms have returned to their original positions after a pivoting operation to be easily carried out from the outside.
