An automotive sunroof is a fixed or operable (venting or sliding) opening in an automobile roof which allows light and/or fresh air to enter the passenger compartment. Sunroofs may be manually operated or motor driven, and are available in many shapes, sizes and styles. == History == Sunroofs, by historical definition, are opaque. The first car company to offer a sunroof as a standard option was the Nash Motor Company as an option on some of its 1937 models. Today, most factory sliding sunroof options feature a glass panel and are sometimes marketed as moonroofs, a term introduced in 1973 by John Atkinson, a marketing manager at Ford for the Lincoln Continental Mark IV. For the first year, Ford sent out its Mark IVs to American Sunroof Company for offline installation. Variations of both the sunroof and moonroof have become the norm in both factory installed and aftermarket offerings, creating a wide range of features and choices. Sunroof systems may be manual or electric, while most moonroof systems are electric/electronic. Manual sunroofs may be lever actuated, as in venting type pop-ups, manual lever or crank operated for sliding systems. Electric roof systems are usually cable driven by a motor and feature some form of sliding opening. Most moonroof systems today are electric and have either a combination pop-up/inbuilt or a pop-up/spoiler configuration (see sunroof types below). Roof systems may be original equipment, factory options (provided by the car company), or installed aftermarket by a roof installation professional for the car dealer or retail customer. Once the vehicle leaves the assembly line, the factory option can no longer be integrated into the roof, making aftermarket the only option. Open sunroofs have occasionally led to break-ins using small children or to practical jokes such as filling a car's interior with Styrofoam peanuts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sunroof」の詳細全文を読む スポンサード リンク
