Abstract
The present invention provides a small and simple shock sensor which can be easily assembled. The shock sensor includes a hermetically sealed case extending along a direction substantially perpendicular to the direction in which a shock is to be detected and a fixed reed and a movable reed sealed inside the hermetically sealed case so as to extend in the lengthwise direction thereof. The movable reed is formed of a weight member and a supporting member which elastically supports the weight member. The shock sensor is structured so that when the weight member moves in the detected direction due to a shock, the contact of the tip of the weight member presses against the contact of the tip of the fixed reed and closes the space between the fixed reed and the movable reed.
