Abstract

PURPOSE:To enable smooth elevation of an elevating rod even if a large air resistance is applied to a front spoiler by forming a rack on the front surface side of an elevating rod, and disposing a motor for driving a pinion meshed with a rack on the elevating rod and on the side of the pinion. CONSTITUTION:When a motor 23 is operated, a pinion 21 is driven through reduction gears 22, 26, so that an elevating rod 10 where a rack 12 is formed is elevated to adjust the projection amount of a front spoiler 6 projected downward from a front bumper 1. When a large air resistance is applied to the front spoiler 6, the elevating rod 10 is subjected to backward force and separated from the pinion 21, so that the engagement between the pinion 21 and the rack 12 is loosened, but not tightened so as to smoothly elevate the elevating rod 10. The motor 23 and the elevating rod 10 are disposed adjacent to each other on the side, so that the occupation area of the device can be reduced.
