A clinometer apparatus includes a first measurement member, a second measurement member, and a coupling member. The first measurement member includes a first plate on which first angle indices are formed, and a first coupling unit that has a circumferential :surface on which second angle indices are carved. The second measurement member includes a second plate, a second coupling unit that is coupled to the first coupling unit due to the coupling member, and a compass that is coupled to the second plate. The coupling member couples the first coupling unit and the second coupling unit so that the second measurement member rotates relative to the first measurement member about a rotational axis of the first coupling unit. |
