  • the extending surface 592a is a surface extending forward from the outer peripheral surface 510a. More specifically, the extending surface 592a extends in a direction that is flush with the outer peripheral surface 510a and in a direction away from the swinging protrusion pin 544.
  • the protruding surface 592b is formed by connecting with the extending surface 592a.
  • the protruding surface 592b is formed at a position that protrudes from the outer peripheral surface 510b and is separated from the outer peripheral surface 510b.
  • the protruding surface 592b is formed substantially parallel to the outer peripheral surface 510b.
  • the locking surface 592 connects to the protruding surface 592b and the outer peripheral surface 510b.
  • the locking surface 592 projects in a direction away from the outer peripheral surface 510b.
  • winding operation lever 500-1 can rotate (swing) with the swinging protrusion pin 544 as the rotation center O2.
  • the outer peripheral surface 510c of the take-up operation lever 500-1 has a recess 520. As shown in FIG. 13, the engaging end portion 174 of the take-up operation lever opening 170 can enter and come into contact with the recess 520. When the engaging end portion 174 comes into contact with the recess 520, the upper limit position (first rotation angle) of the take-up operation lever 500-1 can be determined.
  • the take-up operation lever 500-1 is subjected to urging force by the coil spring 580.
  • the take-up operation lever 500-1 rotates counterclockwise (first direction) due to the urging force of the coil spring 580, and the take-up operation lever 500- 1 returns to the upper limit position (first).
  • the upper limit position can be set to a constant position, and the upper limit position can be set to the reference position.
  • the protruding portion 590 is provided at the portion where the outer peripheral surface 510a and the outer peripheral surface 510b of the winding operation lever 500-1 intersect.
  • the protruding portion 590 protrudes from the opening 170 for the winding operation lever.
  • the locking surface 592c of the protrusion 590 can be engaged with the upper end 173 of the opening wall 172 formed in the left housing 110L.
  • the lower limit position (second rotation angle) of the take-up operation lever 500-1 can be determined by engaging the protruding portion 590 with the upper end portion 173.
  • the take-up operation lever 500-1 When the operator applies a force to the take-up operation lever 500-1 against the urging force of the coil spring 580, the take-up operation lever 500-1 is rotated clockwise (second direction) by the force applied by the operator. It rotates and the take-up operation lever 500-1 can move to the lower limit position. By engaging the locking surface 592c of the protruding portion 590 with the upper end portion 173, the winding operation lever 500-1 can be positioned at the lower limit position. By setting the upper end portion 173 to the lower limit position, the take-up operation lever 500-1 can be positioned at a fixed position.
  • the rack and pinion mechanism is formed by the inclined large tooth surface of the rack portion 564 of the take-up operation lever 500-1 and the inclined large tooth surface of the ratchet gear 322 of the take-up reel 300. It is composed.
  • the cleaning body CT When the cleaning body CT is pulled, the cleaning body CT is newly sent out from the supply reel 200, and the clean resin layer RL of the cleaning body CT is supplied to the cleaning head portion 412 of the cleaning head holding body 410 (FIG. 7). (A) See arrow PA3).
