PROBLEM TO BE SOLVED: To increase the carrying property regarding a mouthpiece, and an exhalation measuring apparatus equipped with the same.SOLUTION: The exhalation measuring apparatus includes: a body case 7 which has a cylindrical shape, and of which one end opening becomes an exhalation blowing-in part 5, and of which the other end opening becomes a device fitting part 6; and a filter 8 which is fitted in the body case 7. On the exhalation blowing-in part 5 side in the body case 7, a branching rib 9 for making blowing-in air disperse in the body case 7 is installed. The filter 8 is arranged in a state being in contact with the branching rib 9. On the body case 7 internal surface side on the device fitting part 6 side of the filter 8, a protuberance 10 for preventing the filter 8 from dropping off is formed. On the exhalation blowing-in part 5 side of the body case 7, a protuberance 11 for stacking is formed. On the device fitting part 6 side of the body case 7, a protuberance fitting section 12 for stacking is formed. Then, the inner diameter of the protuberance fitting section 12 for stacking is made larger than the outer diameter of the protuberance 11 for stacking. |
