Claims

[Scope of utility model registration request]

a drive roller provided on a drive shaft and rotationally driven by a drive source; at least one driven roller passing the endless belt between the drive roller; and an endless belt passing between the two rollers; When the endless belt is rotated and tilted at a predetermined angle around the drive shaft from this rotational operating position, the endless belt is swingably supported by a locking member that locks and holds the endless belt at that rotation position and the drive shaft of the drive roller. 1st
The support member and the driven roller are rotatably supported, and the first
a second support member that is swingably moved relative to the support member;
When the second support member is rotated in the hand and belt rotation direction using the connection point with the first support member as a fulcrum while the endless belt is placed in the tilted rotation position, the second support member
An endless belt device comprising: a locking member that locks and holds a supporting member.
