  In the state where the telescopic handle 4 is pulled out upward, as shown in FIG. 1, each cylindrical brake member 15 of the brake mechanism does not contact the wheel of each universal caster 10, and each universal caster 10 freely turns and rotates. Is possible.

  On the other hand, when the user stops and wants to brake the caster, the grip portion 4a of the telescopic handle 4 is pushed down, and the telescopic rod is pushed down to the lowest position. At this time, the pressing member 6 provided at the lower portion in the telescopic handle 4 is pushed down and descends, and the lower engaging portion 6a engages with the engaging portion 18a of the brake lever 18 so that the brake lever 18 is moved downward. Press down.

  As a result, the brake lever 18 rotates downward about the support shaft 17 and the action shaft 16 is lowered as shown in FIG. The braking force generated by the pushing-down force of the telescopic handle 4 at this time is amplified by the moment force from the engaging portion 18a at the tip of the brake lever 18 to the support shaft 17 and is applied to the action shaft 16 by the action of the lever. The applied braking force strongly pushes down the action shaft 16 together with the support rods 15a on both sides.

  As a result, the cylindrical brake member 15 integrated with the support rod 15a is pushed down, and the lower edge of the wheel 11 of the free casters 10 on both sides abuts. Thus, the free casters 10 on both sides are in a braked state. For this reason, even when the carry bag is stopped on an inclined ground or floor such as a slope, the carry bag does not naturally move toward the lower inclined direction due to its own weight, etc. Can be stopped.

  Further, when the telescopic handle 4 is pushed down to the lowest position, the contracted state of the telescopic rods on both sides is locked, and the pressing members 6 on both sides hold the pushed state, so that the brake levers 18 on both sides are lowered as shown in FIG. The brake state that has been rotated is maintained. For this reason, when the telescopic handle 4 is pushed down to be in the stowed state, the brake lock state of the universal casters 10 on both sides is maintained, and the carry bag remains safely stopped.

  Then, in order for the user to travel and carry the carry bag again, the unlocking button 4b of the grip 4 of the telescopic handle 4 is pressed to release the lock, and when the telescopic handle 4 is pulled up, the telescopic rods on both sides extend. Thus, the lower pressing member 6 is released from being pushed down and raised to the base position. For this reason, the depression of the brake lever 18 by the engaging portion 6a of the pressing member 6 is released, and the brake levers 18 on both sides are returned to the state of FIG. 15 is separated from the wheel 11 of each free caster 10, the brake is released, and each free caster 10 can be turned and rotated, and the user can hold the telescopic handle 4 of the carry bag and hold it freely. It can be carried in the direction.

  In this way, the brake operation of the free caster 10 can be easily performed simply by raising and lowering the telescopic handle 4.
