Description of the invention (7) The pair of forward concealed plate portions of the claw member is set in the installation direction gap, so as to learn from the pair and improve the operating efficiency as is customary. The fixed load of the fixing device is due to the more stable structure of the claw member. The bucket structure for the machine (please read the precautions on the back before filling this page). Install the left and right parts of the fastening part of the concealed claw member. A claw-setting member is provided with an opposing gap between the end edge and the front end edge of the bucket body. Therefore, the concealed plate portion is used to conceal the pair when the soil, sand, or gravel is extracted. In this case, the work can be completed comfortably. In addition, it can be supported by the concealed plate portion and fixed to the installation claw. Since the fixture can be reduced, the damage of the fixture is significantly reduced, and the installation site is fixed. As a result, the bucket is significantly reduced in installation claws and has a long life and excellent performance in operation. When a part of the component is damaged, etc., it can be easily replaced, and during the replacement, the above-mentioned alignment gap is often concealed.
