[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a pachinko machine provided with a handle support structure for a pachinko machine according to an embodiment of the present invention.

In FIG. 1, the pachinko machine 10 includes a front frame 20 having a rectangular plate shape, a lower plate member 40 mounted on a lower portion of the front surface of the front frame 20, and a lower plate member 40 mounted from the front side of the lower plate member 40. Operating handle 30 to be operated. The front frame 20 is formed of a substantially rectangular plate material, and a part such as the lower plate member 40 is attached to a lower portion on the front side. An insertion hole 21 that connects the front surface and the rear surface is formed near the lower right end of the front surface of the front frame 20, and the rotating shaft 33 of the operation handle 30 can be led out to the rear through the insertion hole 21. Has become.

The operating handle 30 has a substantially cylindrical tubular portion 31 protruding rearward. A rotating shaft 33 connected to an operating lever 32 penetrates the inside of the tubular portion 31 and extends from the rear end. It is protruding. The operation handle 30 only needs to have at least a cylindrical portion and a rotating shaft that is inserted through the cylindrical portion and that rotates with an operation of rotating an operation lever or the like, and is limited to the above-described shape. No need. For example, the cylindrical portion 31 on the rear end side of the operation handle 30 may be formed in a prismatic shape.

The lower plate member 40 has a plate portion 41 protruding from the vicinity of the center of the plate-like member toward the front surface, and a bearing portion 42 shown in FIGS. It is formed. 2 and 3 show the coaxial receiving portion 42 in a main part perspective view and a main part side view, and are formed in a substantially cylindrical shape protruding forward and rearward at a position closer to the front right side of the lower plate member 40. Have been. The shaft hole 42a of the bearing portion 42 has a slightly larger diameter than the rotation shaft 33 of the operation handle 30 described above, so that the rotation shaft 33 can be inserted and supported rotatably.

On the other hand, the cylindrical portion 31 has a holding hole 31a through which the bearing portion 42 can be inserted, and when the rotating shaft 33 is inserted into the shaft hole 42a of the bearing portion 42, the bearing portion 42 The body itself enters the holding hole 31a of the cylindrical portion 31. Also, the cylindrical portion 31 itself has a fixing screw 31b which cuts the peripheral surface and tightens or loosens the cut portion. After the bearing portion 42 enters the holding hole 31a, the fixing screw 31b is formed. It can be fixed completely by tightening.

In order to mount the lower plate member 40 to the front frame 20, an insertion hole 21 is formed in the front frame 20 in advance. The rear side enters the insertion hole 21. That is, the bearing portion 42 of the lower plate member 40 and the insertion hole 21 formed in the front frame 20 are relatively positioned in consideration of the mounting position of the lower plate member 40 in advance. As a result, the bearing 42 is simultaneously attached to the predetermined position.

In the positioning, the position of the bearing portion 42 in the lower plate member 40 may be specified based on the positional relationship between the insertion hole 21 and the lower plate member 40 with the position of the insertion hole 21 fixed. Alternatively, the bearing portion 42 may be formed at a predetermined position of the lower plate member 40 in advance, and the formation position of the insertion hole 21 may be specified from the position of the bearing portion 42 when the lower plate member 40 is attached. Good. In any case, the step of fixing the bearing member to the front frame as in the related art can be reduced, and the productivity can be improved.

Incidentally, a short columnar cylindrical portion 43 is formed so as to surround the peripheral portion of the bearing portion 42 on the front surface of the lower plate member 40, and this cylindrical portion 43 constitutes a reinforcing structure. Here, the cylindrical portion 43 has a slightly larger diameter so that the cylindrical portion 31 on the rear end side of the operation handle 30 can be inserted. A cut-out portion 43a cut out from the opening end side is formed in a part of the lower peripheral wall of the cylindrical portion 43, and the fixing screw 31b is exposed to the outside when the cylindrical portion 31 is inserted. It is like that.

After the lower plate member 40 has been attached to the front frame 20, as shown in FIG.
5 is inserted from the front side of the bearing portion 42, as shown in FIG. 5, the outer peripheral surface of the end portion of the cylindrical portion 31 enters while closely contacting the inner peripheral surface of the cylindrical portion 43 which is a reinforcing structure. The end of the cylindrical portion 31 abuts against the lower plate member 40 and stops. Thereafter, when the fixing screw 31b is tightened as described above, the operation handle 30 is fixed while holding the bearing portion 42 therebetween.

The operation handle 30 is provided with a cylindrical portion 43 which is in close contact with the outer peripheral surface of the cylindrical portion 31 of the operation handle 30.
Even if an external force is applied from the side, some of the load applied to the bearing portion 42 is absorbed by the cylindrical portion 43, so that the strength is improved as a whole, and in this sense, it can be called a reinforcing structure. In the present embodiment, a short columnar cylindrical portion 43 is disposed so as to surround the peripheral portion of the bearing portion 42, and the cylindrical portion 43 of the operating handle 30 is closely contacted with the outer peripheral surface of the cylindrical portion 31 to form a reinforcing structure. What is necessary is just to be able to improve the support strength of the operation handle 30 in close contact with the peripheral surface of the portion 31, and it can be changed as appropriate.

For example, in the configuration shown in FIG. 6, three projecting ribs 44 are arranged at equal intervals on the same circumference around the bearing 42 on the front surface of the lower plate member 40.
In this case, in the same manner as described above, the operation handle 3
The ribs 44 are in close contact with the outer peripheral surface of the cylindrical portion 31 at 0, so that the supporting strength can be improved. Needless to say, the peripheral surface of the cylindrical portion 31 is not limited to the outer peripheral surface of the cylindrical portion 31, but may include a surface in close contact with the inner peripheral surface of the cylindrical portion 31.

As described above, when the operation handle 30 having the cylindrical portion 31 and the rotating shaft 33 inserted through the cylindrical portion 31 is attached to the pachinko machine 10 and supported, the rotating shaft 33 is rotatably supported. Since the bearing portion 42 and the lower plate member 40 are integrated, the number of assembling steps can be reduced and productivity can be improved. In addition, the cylindrical portion 31 of the operating handle 30 can be formed by the short cylindrical cylindrical portion 43 which is a reinforcing structure. The support strength can be improved by closely contacting the outer peripheral surface.
