PROBLEM TO BE SOLVED: To provide a lubricating oil return part of a multiple disk brake in a first shaft storage part with a simple configuration by effectively utilizing a space therein. SOLUTION: A swollen part 291 is formed in first shaft storage part 191 with a spline groove 191b to fix a friction member of multiple disk brakes 100 and 110 in a case body 190 formed in an inner circumferential surface on the side of a second shaft storage part 192 continuous thereto, and a space part 292 extended to an inner circumferential surface of the first shaft storage part 191 is formed on the swollen part 291. A lubricating oil return passage 293 is formed between the space part 292 and the second shaft storage part 192 by utilizing the inside of a fitting pedestal 191a to fit an oil cooler 260 thereto, and the lubricating oil to lubricate the brakes 100 and 110 is returned to the second shaft storage part 192 to lubricate a bearing 404a of the second shaft storage part 192. |
