A wire-pulling mechanism comprising: a first pulling wire and a second pulling wire each having one end connected to a body to be operated provided at a front end and having an engaged portion at the other end extending rearward from the one end; an operating unit for pulling the first pulling wire or the second pulling wire by a user's tilting operation; and a pulling arm having a first engaging portion that is engageable with or separable from the engaged portion of the first pulling wire and a second engaging portion that is engageable with or separable from the engaged portion of the second pulling wire, the first engaging portion pulling the first pulling wire along a first movement track when the first engaging portion moves rearward in a state where the first engaging portion and the engaged portion of the first pulling wire engage each other, and the second engaging portion moving along a second movement track when the second engaging portion moves to the front end, the pulling of the first engaging portion and the moving of the second engaging portion are caused by a turning motion accompanying the tilting operation of the operating unit, and characterized in that the second engaging portion is configured so that a position of the second engaging portion in a longitudinal direction of the second pulling wire is capable of being displaced closer to the front end than the engaged portion of the second pulling wire, and in that the second pulling wire is configured so as to enter an inside of the second movement track and extend in a straight line, in a neutral state of the operating unit, and in that in a state where the engaged portion of the second pulling wire and the second engaging portion engage each other, the tilting operation of the operating unit causes the second engaging portion to be moved to the front end along the second movement track with respect to the second pulling wire and causes the engaged portion of the second pulling wire and the second engaging portion to be separated from each other. a first pulling wire and a second pulling wire each having one end connected to a body to be operated provided at a front end and having an engaged portion at the other end extending rearward from the one end; an operating unit for pulling the first pulling wire or the second pulling wire by a user's tilting operation; and a pulling arm having a first engaging portion that is engageable with or separable from the engaged portion of the first pulling wire and a second engaging portion that is engageable with or separable from the engaged portion of the second pulling wire, the first engaging portion pulling the first pulling wire along a first movement track when the first engaging portion moves rearward in a state where the first engaging portion and the engaged portion of the first pulling wire engage each other, and the second engaging portion moving along a second movement track when the second engaging portion moves to the front end, the pulling of the first engaging portion and the moving of the second engaging portion are caused by a turning motion accompanying the tilting operation of the operating unit, and characterized in that the second engaging portion is configured so that a position of the second engaging portion in a longitudinal direction of the second pulling wire is capable of being displaced closer to the front end than the engaged portion of the second pulling wire, and in that the second pulling wire is configured so as to enter an inside of the second movement track and extend in a straight line, in a neutral state of the operating unit, and in that in a state where the engaged portion of the second pulling wire and the second engaging portion engage each other, the tilting operation of the operating unit causes the second engaging portion to be moved to the front end along the second movement track with respect to the second pulling wire and causes the engaged portion of the second pulling wire and the second engaging portion to be separated from each other.
