However, the above-mentioned conventional technique has a problem that a key for a gaming machine cannot be efficiently manufactured. This will be described.

The key code of the key for the gaming machine is assigned to each hole. Therefore, the key is ordered for each hole, and the order quantity per hole is small. When the key head is made by insert molding, it is necessary to perform insert molding after processing the key code on the key body, and small lot molding is performed each time an order is received. However, in order to make a key head as designed by insert molding, a preparatory process for determining the conditions of the molding machine by performing trial hitting or the like is indispensable. Performing such a preparatory process each time a small lot is formed makes the manufacturing process extremely inefficient.

By adopting the configuration described in Patent Document 2, molding of a small lot can be avoided. However, in the configuration described in Patent Document 2, as shown in FIG. 7, the space between the two protrusions 111 that engage with the stopping means 106 and connect the head 101 and the shaft 110 is open. With such a configuration, it is not possible to withstand the load due to the tensile stress when opening the opening / closing portion 50 (see FIG. 6) of the gaming machine, and the head 101 may come off from the shaft 110.

Key cord portions 11e having a plurality of cord grooves recessed in a conical shape toward the insertion guide ribs 11d are formed on both sides of the key insertion portion 11c with the insertion guide ribs 11d interposed therebetween.

By using the convex insertion guide rib 11d as the insertion guide, the key insertion portion 11c is located in the shorter direction (see FIG. 7) than the groove-shaped insertion guide (see FIG. 7) as in the key described in Patent Document 2. A wide cross-sectional area (in the direction orthogonal to the central axis of rotation) can be secured, and the configuration can be made resistant to loads due to bending stress. Further, in the present embodiment, since the key 10 has a reversible configuration and the insertion guide ribs 11d are provided on both sides, the cross-sectional area is secured wider than the configuration provided on only one side, and the configuration is resistant to the load due to bending stress. it can.

Further, in the present embodiment, the key body 11 is manufactured by using a cross-shaped rod-shaped drawing material having a convex portion having a size required as the insertion guide rib 11d. Therefore, a convex portion forming the insertion guide rib 11d is also provided in the base portion 11a, and the convex portion is provided over the entire length of the key main body 11. As a result, the key body 11 becomes stronger as a whole, and the resistance to the load of torsional stress, tensile stress and bending stress when fixed by the first and second fixing pins described later can be increased. When the key body 11 is manufactured from a plate material and the insertion guide rib 11d is manufactured by cutting or the like, it is not necessary to form a convex portion connected to the insertion guide rib 11d on the base portion 11a, and the thickness of the plate material can be used as it is.
