PURPOSE: An apparatus for measuring the opening and closing speed of a vehicle door is provided to reduce the consumption of time and manpower by easily detecting the opening and closing speed of the vehicle door. CONSTITUTION: An apparatus for measuring the opening and closing speed of a vehicle door includes an attaching unit, a base unit, a first sensor, a second sensor, a calculation unit(20) and a sensor detection member(30). The attaching unit is attached to one side of the door panel(11) of the vehicle(10). The base unit is installed on the attaching unit. The first sensor is installed on the base unit with spacing apart from the attaching unit, and the second sensor is installed on the base unit with spacing apart from the first sensor at a predetermined distance for sending the open and close of the door together with the first sensor. The calculation unit calculates the speed by measuring the time between the first and the second sensors. The calculation unit(20) is provided with a power supply to provided the power. And, the sensor detection member(30) is installed on the one side of the door panel(11) to detect the first and the second sensors. |
