<p>PROBLEM TO BE SOLVED: To provide a reverse cam device which achieves good balance when being suspended and good workability.SOLUTION: A reverse cam device 1 includes: a base 10 having a substantially box shape; a cam driver 20 which is supported by the base 10 so as to move in a vertical direction; a second cam slide 40 which is supported by the base 10 so as to move in the vertical direction and moves in an upward direction as the cam driver 20 moves in a downward direction; and a coil spring 17 which biases the cam slide 40 to the lower side. A centroid of the reverse cam device 1 is positioned closer to the cam slide 40 side than the cam driver 20. A tool attachment member 18, in which a suspending bolt 50 is attached when the reverse cam device 1 is moved suspended, is provided at a position in the base 10 which is located closer to the cam slide 40 side than the cam driver 20.</p> |
