<p>Provided is a centralized unlocking operation device in which a first operation arm is caused to rotate in response to rotation of a rotor in a normal rotation direction from a neutral position, and a second operation arm is caused to rotate in response to rotation of the rotor in a reverse rotation direction from the neutral position, wherein a first pressing surface (38) for contacting and pressing a first pressure-receiving portion (35) of the first operation arm (33) when the rotor (15) is rotated from the neutral position toward a first operation position, and a second pressing surface (39) for contacting and pressing a second pressure-receiving portion (36) of the second operation arm (34) when the rotor (15) is rotated from the neutral position toward a second operation position are formed on a cam portion (37) provided to the rotor (15), and wherein a spring (32) is provided between the first and second operation arms (33, 34) so as to urge the first and second operation arms (33, 34) in such a direction that the first and second pressure-receiving portions (35, 36) are caused to contact the first and second pressing surfaces (38, 39). This makes it possible to confirm easily from outside whether or not each of the two operation arms has returned to the original position after the rotational operation.</p> |
