DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a down-swing holder which is small and portable.

[0002]

2. Description of the Related Art
The same type of small bobbin holder on the market is equipped with a mainspring in a bobbin bobbin that is rotatably provided in the main body case. The weight is suspended in a fixed state, and the swinging operation is performed.

[0003] By holding a weight after use, the bobbin thread has been automatically wound by the restoring force of the mainspring.

[0004] However, in these conventional small bobbin cages, the spring is mounted naked inside the bobbin in the main body case, so that if rainwater enters into the housing of the spring, it becomes dirty water and contaminates the spring. Rust is easily generated, and when the mainspring is rusted, the automatic winding function of the bobbin thread becomes defective or unusable.

The present invention solves the above-mentioned drawbacks by focusing on preventing rainwater from entering the storage case of the mainspring, and has completed the present invention.
