As is apparent from the above description, claim 1
According to the invention described in (1), the rear legs provided on each girder can be engaged with the upper supports of the left and right front suspensions, and the front legs provided on each girder can be placed by selecting the strength portion of the front part of the vehicle body. As described above, since both ends of the cross beam can be positioned at arbitrary positions of each girder, it can be installed on a predetermined strength member without being affected by a vehicle type, and can withstand a large load, and can be installed in an engine room. A predetermined working space can be formed in a place where the above is required. According to the second aspect of the present invention, since the flange formed on the upper surface of the spring upper support is sandwiched by the engaging tool, even if the screw portion of the bolt of the upper support does not protrude upward, The rear leg can be firmly engaged with the upper support. According to the third aspect of the present invention, since different types of abutments can be exchanged at the lower portion of each front leg, it is possible to easily cope with strength members having different shapes. According to the invention described in claim 4, the hoist is provided on the cross beam so as to be movable in the left-right direction and swingable about the vertical axis. Hook), and a large bending moment is not generated in the cross beam even if the locking portion moves when the engine is lifted, so that the engine can be lifted safely and stably. .
