造。 Track frame 5a of crawler type traveling device 5
A swivel base mounting cylinder 7 is attached vertically to the cylindrical body 7, a flange 8 is attached to the upper end of the cylindrical body 7 with the flange 8 projecting outward from the cylindrical body 7, and a large-diameter swivel race placed on the flange 8 is attached to the upper end of the cylindrical body 7. In a swing-type work vehicle in which a bolt insertion hole 10 for fixing is arranged on the outside of the cylindrical body 7, a first steel plate 11a and a second steel plate 11b formed in an annular shape are stacked on top of each other and integrated. A connected spacer 11 is interposed between the flange 8 and the small diameter turning lane 12, and the inner diameter of the first steel plate 11a placed on the flange 8 is set to be smaller than the inner diameter of the flange 8 and the inner diameter of the cylindrical body 7. The inner diameter of the second steel plate 11b on which the small diameter turning race 12 is placed is set to be larger than the first steel plate 11a.
A first bolt 13 formed smaller than the inner diameter of the bolt and passed through the bolt insertion hole 10 of the flange 8 is inserted into the first bolt.
and second steel plates 11a and 11b are fitted with screws,
The second bolt 14 passed through the bolt insertion hole of the second steel plate 11b is screwed into the small diameter turning race 12, and the head 14a of the second bolt 14 is inserted between the flange 8 and the second steel plate 11b. A swivel race mounting structure for a swivel work vehicle that is placed in between.
