However, the length of the axially extending portion may be adjusted by a structure in which the bolt is fixed to the first flat plate portion through the long hole provided in the first rod-like member. Further, the length of the orthogonally extending portion may be adjusted by a structure in which the bolt is fixed to the coupling portion main body through an elongated hole provided in the second rod-like member.

  Moreover, the case where the length of the axial direction extended part 76 of the jig | tool 50 can be adjusted was demonstrated. However, the length of the axially extending portion of the jig may not be variable, and the jig may be a dedicated item for a return gear device in which the distance between the mounting plate and the side surface of the sheave is a predetermined length. . Alternatively, the jig may be configured such that a plurality of cleaning portions having different sizes can be attached and detached, and the axial length can be adjusted by changing the size of the cleaning portions.

  Moreover, the case where the length of the orthogonal direction extension part 77 of the jig | tool 50 can be adjusted was demonstrated. However, the length of the orthogonal extension of the jig may not be variable. The case where the cleaning unit 95 is detachable from the orthogonally extending unit 77 will be described, and one or more replacement cleaning units having different lengths from the cleaning unit 95 can be detachably attached to the orthogonally extending unit 77 The case was described. However, the cleaning part may not be removable from the orthogonal extension.

  Further, the case where the portion of the first rod-like member 73 coupled to the coupling main body 79 can be varied has been described. However, the first rod-like member may be formed integrally with the coupling portion, or the first rod-like member may not be moved relative to the coupling portion.

  Moreover, the case where the 1st rod-shaped member 73 has a cross-sectional substantially rectangular shape, and the 2nd rod-shaped member 74 is a round rod member was demonstrated. However, the cross-sectional shape of the first and second rod-shaped members may be any shape, for example, square, rectangular, circular, semicircular, polygonal or the like.

  Moreover, the case where the jig | tool 50 was equipped with the sheet member 52 with a magnet was demonstrated. However, the jig may not include the magnet-attached sheet member, and the cleaning operation using the jig 50 may be performed in a state in which the sheet member is disposed below the jig 50.

  Further, the case of cleaning the return wheel 6 suspended from the ceiling of the hoistway 11 by the jig 50 has been described. However, the return car installed on the bottom side of the basket may be cleaned by the jig of the present invention. Although the case where the jig body 51 is fixed to the lower end of the mounting plate 22 has been described, the jig body may be fixed to the upper end of the mounting plate.
