Abstract
An acceleration detecting device comprising a movable weight, a movable electric contact disposed on the weight, a fixed electric contact, an resilient member, and a friction creating mechanism. The movable electric contact slides on the fixed electric contact when a force is given to the weight for moving the weight in a first direction. The resilient member urges the weight continually in a second direction opposing to the first direction. The friction creating mechanism gives a frictional force to the weight when the weight travels a distance in excess of a certain amount in the first direction. The friction creating mechanism increases the frictional force as the weight continues to advance further in the first direction.
