  • the glass sheet GS is lowered from above the frame 4, and its lower end GSb is brought into contact with the support wire 10 (first portion 10a) of the frame 4.
  • the lower end GSb of the glass sheet GS is slid relative to the support wire 10 and moved downward. That is, in the accommodation step, the support wire 10 functions as a guide portion that guides the glass sheet GS into the accommodation space S.
  • the accommodation step is completed by bringing the lower end GSb of the glass sheet GS into contact with the support surface 25 of the end support 12.
  • the glass sheet GS is in a state in which one main surface GSa is supported by the support wire 10 and the lower end GSb is supported by the end support 12 (a state shown by the two-dot chain line in FIG. 11).
  • the frame 4 containing the glass sheet GS is moved downward from an upper position in the cleaning tank 3.
  • the frame 4 is immersed in the cleaning liquid CL in the cleaning tank 3 from its lower part (first bar 5).
  • part of the glass sheet GS may float up and become deformed while the frame 4 is immersed in the cleaning liquid CL.
  • the restraining wire 11 of the frame 4 comes into contact with part of the deformed glass sheet GS, preventing excessive deformation of the glass sheet GS. This reliably prevents damage to the glass sheet GS due to deformation.
  • the frame 4 descends in the cleaning tank 3 until the fourth bar 8 comes into contact with the support table 30 of the support devices 27a and 27b.
  • the fourth bar 8 of the frame 4 is brought into contact with the support surface 30a of the support base 30 of the cleaning tank 3.
  • the pressing member 28 is placed on the fourth bar 8.
  • the pressing portion 31 of the pressing member 28 comes into contact with the fourth bar 8
  • the fixing portion 32 of the pressing member 28 comes into contact with the support surface 30a of the support base 30.
  • the second through hole 32a and the third through hole 32b of the fixing portion 32 are aligned with the pair of screw holes 30b, 30c of the support base 30, and the second fixing member 29b and the third fixing member 29c are inserted into the respective through holes 32a, 32b and the respective screw holes 30b, 30c.
  • the pressing member 28 is fixed to the support base 30.
  • the frame 4 is placed in an inclined position, the first fixing member 29a is inserted into the first through-hole 31a of the pressing member 28, and the fourth bar 8 is fixed.
  • the frame 4 is supported by the support devices 27a, 27b while maintaining the inclined position.
  • the inclination angle ⁇ (see FIG. 2) of the frame 4 (side bars 9a, 9b) with respect to the vertical direction is 65° or more and 85° or less.
  • the glass sheet GS contained in the frame 4 is supported by the frame 4 in an inclined position and is entirely immersed in the cleaning liquid CL in the cleaning tank 3.
  • the ultrasonic generator 3a in the cleaning tank 3 is started, and the glass sheet GS supported by the sheet support 2 is cleaned with the cleaning liquid CL.
  • the frame 4 is released from the support devices 27a and 27b, and the frame 4 is removed from the cleaning tank 3 together with the glass sheet GS.
  • the contact area of the support wire 10 of the sheet support device 2 with the glass sheet GS is extremely small, and no large impact is applied to the glass sheet GS. Moreover, since the support wire 10 contacts only one of the main surfaces GSa of the glass sheet GS without contacting the side ends of the glass sheet GS, no large impact is applied to the side ends of the glass sheet GS. In this way, by supporting the glass sheet GS with the support wire 10, damage to the main surface and ends of the glass sheet GS during the preparation process and cleaning process can be effectively prevented.
  • the sheet support 2 can adequately support the lower end GSb of the glass sheet GS without damaging it by configuring the first support portion 21 of the end support 12 from an elastic material.
  • the present invention is not limited to the configuration of the above embodiment, nor is it limited to the above-mentioned effects. Various modifications of the present invention are possible without departing from the gist of the present invention.
  • the support wire 10 and the restricting wire 11 are fixed by wrapping them around the first bar 5, but the present invention is not limited to this configuration.
  • the support wire 10 and the restricting wire 11 may be fixed to the first bar 5 by gluing or welding, or by using pins or screw members.
  • each wire 10, 11 may be fixed to the first bar 5 by forming through holes in the first bar 5 and inserting the support wire 10 and the restricting wire 11 through the through holes.
  • the support wire 10 may be fixed to the second bar 6, and the restricting wire 11 may be fixed to the third bar 7.
