Abstract:
1. A six-direction indicator provided in an XYZ rectangular coordinate system, comprising: an inclined crank mechanism comprising a shaft that extends in an X-axis direction and a rotation member rotatable around an inclined axis inclined with respect to said shaft and coupled to said shaft; a driving source that rotates said shaft around the X-axis; and a guide member having a zigzag circumferential edge provided around the X-axis of said inclined crank mechanism and bent alternately in a mountain-like shape and a valley-like shape at intervals of 60° around the X-axis, said rotation member comprising a guide pin provided around the inclined axis of said rotation member and in contact with said circumferential edge, said guide pin moving around on said circumferential edge by rotation of said shaft and indicating one of positive and negative directions on U, V, and W axes crossing one another at intervals of 60° around the X axis.
