Claims

[Scope of utility model registration request]

Attach the boom to the front part of the hydraulic excavator,
In a work attachment in which an arm and a bucket are sequentially connected to the tip of the boom, the outer periphery of the tip boss member at the tip of the arm communicates with the grease reservoir inside the tip boss member in a direction facing the idler link mounting boss member. A block member having a grease inlet and a grease passage communicating with the grease inlet is fixed to the rear of the tip boss member, and a threaded hole in the tip side of the block member communicates with the grease passage. On the other hand, a support hole for supporting the greasing pipe is provided in the middle part of the above-mentioned boss members of the arm side plate, and a greasing pipe is connected to the support hole and the threaded hole of the block member. A grease nipple is provided in the counterbore hole in the head of the tube body, and by supplying grease to the grease nipple, grease is delivered to the grease reservoir of the tip boss member through the inner diameter passage inside the tube body. A greasing structure at the tip of the arm, which is configured so that it can be supplied.
