摘要： An instrument casing having an opening therein exposing a pointer and a dial therefor. A sealing member is carried by the casing adjacent the opening thereof. A lens is disposed in the opening and is provided with an outer periphery that is disposed against the sealing member. A lens ring is disposed against the other side of the outer periphery of the lens to hold the lens in the casing opening. The lens ring has an interlocking part thereof disposed against the outer peripheral edge of the lens between the sides thereof to lock the lens ring to the casing and, thus, the lens in the casing opening. A separate annular spacing member is disposed in the casing opening against the end wall thereof to hold the sealing member in spaced relation from the dial plate, the spacing member carrying an annular spring adapted to be compressed between the sealing member and an end wall of the casing to maintain the sealing member in sealing engagement with the lens.
