造。 In a work attachment in which a boom, arm, arm link, bucket link, etc. are pinned to the front part of a construction machine so as to be able to rotate freely with respect to each other to form a link mechanism, the lower boss end of the arm link at the joint between the arm and the arm link. An end cover is fixed to the arm side, and a grease groove and a grease reservoir are provided inside the end cover, which are separated by a seal.The grease reservoir is communicated with the grease passage inside the pin, so that the arm boss can be supplied with grease. The grease groove passes through the grease passage in the lower boss of the arm link, the pin grease groove, the external piping, the grease passage in the upper boss of the arm link, the pin groove, and then the arm link and bucket link, and the arm link at the joint of the bucket cylinder. Grease can be sent to the end cover fixed to the bucket link side at the end of the upper boss, and it is also possible to send grease to the distribution valve via the grease groove and grease passage inside the end cover, and from the distribution valve to external piping and inside the end cover. Grease can be supplied to the internal greasing section of the bucket cylinder through the grease passage and grease reservoir separated by a seal from the grease groove, and the pin grease passage, and each boss part of the bucket link can also be supplied with grease via external piping. A greasing circuit structure for a link mechanism in a construction machine, characterized by:
