PURPOSE: A vibration transfer checking apparatus is provided to allow users to easily recognize vibration transfer characteristic of a structure, such as a bed, by installing the vibration transfer checking apparatus in the structure. CONSTITUTION: A vibration transfer checking apparatus includes a base(10), on which a spring structure and a pocket spring structure are installed while being spaced from each other. The spring structure is separated from the pocket spring structure by means of a partition plate(11), which is installed at an upper middle portion of the base(10). Striking members(20,20') are provided at both sides of a transverse plate(13), which extends through an upper portion of a frame(12), in order to apply impact to the spring structure and the pocket spring structure. The striking members(20,20') are formed with guide holes for receiving a pair of guide rods(14).
