摘要： PROBLEM TO BE SOLVED: To improve the design freedom and attaching strength by strongly attaching a revolving bearing to a bottom plate at a free position regardless of the position of a vertical plate of a revolving frame.SOLUTION: On a right vertical plate 13 of a revolving frame 10, a notched part 15 opened to the lower side at a position facing each female screw hole 11C provided on a bottom plate 11 is provided. Thus, even when providing the female screw hole 11C on the lower side of the right vertical plate 13, since the notched part 15 can evade the distal end part of a bolt 18 projected to the upper side from the female screw hole 11C, the female screw hole 11c is freely arranged at a position at which high attaching strength can be obtained. Also, a reinforcing block 17 is provided so as to fill a space part 16 formed between the notched part 15 and an upper surface 11A of the bottom plate 11, and the reinforcing block 17 is fixed to the bottom plate 11 and the right vertical plate 13 by using welding means. Thus, concentration of large loads on the notched part 15 is prevented.

摘要： PROBLEM TO BE SOLVED: To enhance work efficiency when a hydraulic source and a front wheel brake device are connected by a hydraulic hose for a front wheel brake.
SOLUTION: A hydraulic hose 40 for a left front wheel brake is two-divided to a hydraulic source side hose 40A and a brake device side hose 40B, and a connection portion between the respective hoses 40A, 40B is fixed to a front axle housing 17 through a left relay member 42. Thereby, the hydraulic source side hose 40A may be arranged while only taking into consideration deformation accompanied by the pivoting of the front axle housing 17, and the brake device side hose 40B may be arranged while only taking into consideration deformation accompanied by steering operation. As a result, the booster 36 and the left front wheel brake device 25 can be quickly and easily connected by the hydraulic hose 40 for the left front wheel brake comprising the hydraulic source side hose 40A and the brake device side hose 40B, and the work efficiency can be enhanced.

摘要翻译：要解决的问题：当液压源和前轮制动装置通过用于前轮制动器的液压软管连接时，提高工作效率。解决方案：用于左前轮制动器的液压软管40分为液压源侧软管40A和制动装置侧软管40B，并且各软管40A，40B之间的连接部分固定在前部轴箱17通过左中继构件42.因此，液压源侧软管40A可以仅在考虑到伴随前桥壳体17的枢转的变形的情况下被布置，并且制动装置侧软管40B可以仅布置考虑到伴随转向操作的变形。结果，增压器36和左前轮制动装置25能够通过用于包括液压源侧软管40A和制动装置侧软管40B的左前轮制动器的液压软管40和工件效率可以提高。版权所有（C）2010，JPO＆INPIT
