PROBLEM TO BE SOLVED: To provide a perpendicularity measuring device capable of visually confirming an inclination in longitudinal and lateral directions on the same display surface and capable of promptly understanding at a glance given to the display surface that the perpendicularity is obtained in the longitudinal and lateral directions.SOLUTION: A display surface 6 of a perpendicularity measuring device 1 is formed with a perpendicular scale line 7 and a horizontal scale line 8. The perpendicularity measuring device 1 is attached to a pile 30 of a measurement object by magnets 4a, 4b. The presence or absence of an inclination in a horizontal direction of the pile 30 can be confirmed depending on whether or not a first pointer 11 hung from a first spindle 13 of the display surface 6 of the perpendicularity measuring device 1 matches the perpendicular scale line 7. The presence or absence of the inclination in a forward and backward direction can be confirmed depending on whether or not a second pointer 12 hung from a second spindle 14 of the display surface 6 matches the perpendicular scale line 7 and the horizontal scale line 8. |
