Abstract
A monitor camera (1) has a front glass (13) and a glass hold-down plate for holding the front glass (13). The glass hold-down plate has an outer surface in a region continues to the front glass (13), and the outer surface is flush with or stepped back from an outer surface of the front glass (13). Further, the glass hold-down plate has a hold-down portion vertical to the direction of the thickness of the front glass (13), the hold-down portion presses the held-down portion stepped back from the outer surface of the front glass (13). The above structure prevents the field of vision of the monitor camera (1) from being hindered by natural substances including snow lying on the front glass and enhances waterproof property of the monitor camera.
