When the rim lifting portion 30 is raised to a predetermined height facing the engaging portion 52 on the support 15 side, the engaging member 51 provided in the rim lifting portion 30 stops the driving cylinder 44. Thereby, the rim lifting part 30 is in a state of being retracted to a position away from the first rim 21 .

Next, the tire T that has been cooled while being held by the first rim 21 and the second rim 22 located on the lower side of the tire grip portion 20 is taken out. Therefore, the support shaft 24 is rotated to reverse the upper and lower first rims 21 and the first rim support portion 23. Then, the cooled tire T held by the first rim 21 and the second rim 22 located on the lower side is moved to the support shaft 24 side. Further, the uncooled tire T newly installed as described above is moved to the lower side of the support shaft 24.

Further, as shown in FIGS. 5 and 6, the engaging member 51 is advanced to the stay 15 by the advance/retract cylinder 35, and is engaged with the engaging portion 52. Thereby, the rim lifting portion 30 is engaged with the stay 15 at the retracted position after leaving the first rim support portion 23.

When the engagement member 51 is engaged with the engagement portion 52 in this manner, the second hole portion 57b of the through hole 57 of the engagement member 51 is moved to the position of the fixing member 62. Therefore, in the connection mechanism 60, the connection between the rim lifting unit 30 and the unloader 40 is released.

Next, as shown in Fig. 11, the unloader 40 is lowered. Therefore, the drive cylinder 44 is extended downward. Then, the rim lifting portion 30 remains engaged with the stay 15 at the retracted position after leaving the first rim support portion 23, and only the unloader 40 is lowered.

As shown in Fig. 7, the key portion 54 of the engaging member 51 that is engaged with the engaging portion 52 is retained by the weight of the rim lifting portion 30 itself while being held by the rim lifting portion 30 that is engaged with the stay 15 It is pushed downward and is engaged with the key engaging portion 55.
