The present invention relates to an assembling structure in which bent gutters divided into a plurality of members are integrally connected in a one-touch manner. 2. Description of the Related Art In general, a bent gutter of such a pachinko machine has a plurality of bent ball passages, a discharge preventing device for preventing payout of a prize ball when a ball runs out, and a closed hall. It is formed in a complicated structure in which a ball extracting device for extracting the remaining balls of the prize ball tank is installed. Therefore, in order to simplify the production, for example, a plurality of divided shafts are formed vertically, and a plurality of connecting shafts having screw insertion holes formed in each of the divided members are provided horizontally, and screws are respectively inserted into these screw insertion holes. It is inserted and tightened, and the parts formed separately are joined together. [0003] Such a conventional bent gutter assembly structure requires a cumbersome operation of tightening screws to a plurality of long connecting shafts, and the screws are tightened. It was troublesome. Therefore, an object of the present invention is to solve such problems found in the prior art, and it is possible to form a plurality of divided members so that they can be combined in a one-touch manner without any need for screw tightening. An object of the present invention is to provide a gutter assembly structure .

Further, the mechanism plate 3 has a first winning ball discharge processing mechanism 14 for discharging the winning balls collected in the first winning ball collecting section 4 one by one to the outside of the machine and a second winning ball set. A second winning ball discharge processing mechanism 15 for discharging the winning balls collected in the section 5 one by one to the outside of the machine is provided. Then, a predetermined number, for example, thirteen prize balls are discharged from the first prize ball discharge mechanism 11 to the prize ball discharge gutter 13 by the operation of the first prize ball discharge processing mechanism 14, and the second prize ball discharge processing mechanism. By the operation of 15, a predetermined number, for example, seven prize balls are discharged from the second prize ball discharge mechanism 12 to the prize ball discharge gutter 13. The bent gutter passage 10 of the bent gutter 10
Vertical ball passages 16a to 16c are provided continuously below a to 9c,
Further, a ball extraction device 17 is incorporated below the bent gutter 10, and a discharge prevention device 18 is provided in the vertical ball passages 16a to 16c. The discharge preventing device 18 prevents the operation of discharging the prize balls when the prize balls supplied to the first and second prize ball discharging mechanisms 11 and 12 are interrupted or emptied. ~ 19c and micro switch 20a
