A stuffed toy is built with a sound source member, a plate spring, and a stationary plate. The sound source member has the function of producing a sound through its oscillation. One end portion of the plate spring is connected to the sound source member. The stationary plate is attached to part of the plate spring ranging from the other end portion opposite from the above one end portion to a predetermined position, to hold the part of the plate spring. Simply rocking the stuffed toy causes the sound source member to oscillate with the above predetermined position as the fulcrum and then to receive pressure, thereby producing a sound.
