Abstract
A power window apparatus with a safety device capable of taking a safety measure when it detects the neck or hand of a passenger being caught in the window, which device can exactly detect such a dangerous state and take a reliable safety measure to correct for the same, irrespective of variations of ambient temperature. A temperature sensor provided which senses the temperature of the motor acting as a drive source for moving the window. This temperature is closely related to the ambient temperature. A reference value for the motor speed for detecting an object-caught state is altered according to the detected temperature, thereby providing exact detection of the object-caught state irrespective of temperature variations. Preferably, the power transmission for the window, the temperature sensor, and a controller structure are mounted on an inner side of a single housing.
