Abstract: A game machine makes it possible to make an accurate determination of not only success but also failure with regard to a predetermined play action, and can handle various play rules. The game machine includes at least one game machine main body, and at least one game machine sub unit configured to enable a play by being arranged in a predetermined position on the game machine main body, and is characterized in that, to provide an evaluation of successful play when the game machine sub unit is positioned in the predetermined position on the game machine main body, the game machine main unit and/or the game machine sub unit is provided with a position grasping unit for grasping a positional relationship of the main body and the sub unit. The position grasping unit includes a sensing device utilizing an electric change.

Abstract: A muffler includes a shell main that is formed in a cylinder with two openings opposite to each other being apart from each other in an axial direction of the shell main body by rolling a flat plate to have an overlapped portion overlapping an inner end portion and a shell portion, and a pair of end plates that are partially inserted in the openings of the shell main body and fixed to the shell main body. The inner end portion is formed with two cut-off portions at opening-side edges of the inner end portion, respectively, to avoid interference between the inner end portion and the end plates when the end plates are inserted into the openings of the shell main body.
