  Therefore, unlike the prior art, there is no need to increase the click force, the operation portion can be operated with a light operation force, and the operability is good.

  According to a second aspect of the present invention, either the shaft side tubular portion or the cable side tubular member integrally formed with the control cable is rotated by the operation of the operation portion. Then, the end projecting from the outer periphery of the spring main body abuts on the periphery of the elongated hole portion, and both ends are moved in the expanding direction, whereby the spring main body is It becomes rotatable along the outer peripheral surface of the bearing tube portion.

  Therefore, the operation pulley is allowed to rotate by the operation portion, and the rotation of the operation pulley is transmitted to the driven pulley via the control cable.

  Therefore, the movable member can be operated from the operation unit side.

  Further, when a pushing back force is applied from the movable member side, even if either the shaft-side tubular portion or the cable-side tubular member formed integrally with the control cable is rotated, the length An end protruding from the outer peripheral edge of the spring main body abuts on the peripheral edge of the hole, and the end of the spring is moved between the both ends in the closing direction. It is fastened to the outer peripheral surface and cannot be rotated.

  Therefore, the operation unit is held so as not to move depending on the pushing back force.
