Problems solved by technology

[0005] However, when the upper arm 12 and the lower arm 14 of the above-mentioned conventional vehicle jack are hinged by the hinge shaft 20, since they are hinged by the bolt 13, there is a disadvantage that the man-hours of work increase and the assembly performance and productivity decrease.
[0006] In addition, since the upper arm 12 and the lower arm 14 are hinged to the hinge shaft 20 by the bolt 13, there is a problem that the wear of the bolt 13 caused by long-term use may cause failure or decrease in strength.
