Abstract
A wiper device comprising a wiper motor; a storage section storing specific positions at an upper and a lower portions of a region on the window glass where the wiper blade swings as a first upper stop target position and a first lower stop target position, and also storing specific ranges from the first upper stop target position to a lower side and from the first lower stop target position to an upper side as an upper and a lower permissible stop ranges; a detection section that detects rotation speed and rotation angle of the wiper motor; and a control section that identifies the wiper blade position, reduces the rotation speed of the wiper motor as the swinging wiper blade approaches the upper or the lower permissible stop range, and stops the wiper motor rotation when the wiper blade has stopped in the upper or the lower permissible stop range.
