Claims

[Scope of utility model registration request]

a drive shaft rotatably provided in a fixed position and having an upper rim for gripping the tire at one end thereof;
A tire chuck which is provided so as to be movable forward and backward toward the drive shaft, rotatably holds a lower tire gripping rim corresponding to the upper rim at one end thereof, and has a fluid pressure cylinder as its forward and backward drive source. A tire chucking device, characterized in that a tire internal pressure supporting member is provided on the forward and backward shaft so that it can be rotated up and down along with the movement of the forward and backward axis, and the driving source for the up and down rotation is a fluid pressure cylinder. .
