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.
