Abstract
Abstract One end of a base plate is formed with an elongated opening and the other end rotatably supports the base end of an elastic plate whose free end is inserted in the above mentioned elongated opening. The elastic plate is longer than the base plate and formed with an engagement projection adjacent the free end thereof. In setting the elastic plate, it is upwardly curved and an engagement member is interposed between the upper surface of the base plate and the engagement projection so as to engage the elastic plate and maintain its curved condition. The engagement member will be moved by a small animal taking a bait or by the weight of a small animal treading on the base plate. Such movement of the engagement member results in relieving the engagement, so that the elastic plate is instantaneously elastically restored to its flat condition, thereby trapping the small animal by squeezing it between the base plate and the elastic plate.
