Description

  The present invention relates to an operation handle for adjusting the firing strength of a game ball in a gaming machine.

  In a gaming machine such as a pachinko gaming machine, an operation handle that adjusts the launch intensity of a game ball to the gaming area does not generate excessive friction when the rotating ring part is rotated with respect to the fixed base part. In addition, it is necessary to provide an appropriate gap between the two due to the structure. The operation handle is configured by assembling a plurality of parts. For this reason, in the operation handle, a backlash (play portion) due to a dimensional tolerance of each part or the like occurs, and this exists as a gap.

  Further, usually, the return type spring is provided with a return type spring for returning the rotation ring portion to the initial position. And a player rotates a rotation ring part against the urging | biasing force by a return spring. At this time, in order to maintain the target launch strength of the game ball, it is necessary to hold the turning ring portion at a predetermined turning position, and in order to perform this holding, the urging force by the return spring is always the player. Will be added to the hand. Therefore, the player wants to perform an act of inserting a foreign object such as a coin into the gap between the fixed base portion and the rotation ring portion and holding the rotation ring portion at a predetermined rotation position.

  In a gaming machine such as a pachinko gaming machine, for example, an operation handle that adjusts the launch intensity of a game ball to a game area is disclosed in Patent Document 1. In the bullet ball game machine of this patent document 1, a coin or a game ball is inserted into a gap between a rotatable turning ring for adjusting the striking force of the launching device and another member, and the turning ring is fixed. It is disclosed to provide a fixing blocking member for blocking the action. And in patent document 1, while eliminating the fixing action of a rotation ring and contributing to the soundness of a game, the device which prevents the breakage | damage of the handle resulting from a fixing action is performed.

  In addition, the gaming machine of Patent Document 2 includes a rotating member that can control the momentum at which the game ball is launched based on the rotation angle, and a pair of restricting members that restrict movement of the rotating member from both sides in the thrust direction. A firing handle is disclosed. In this firing handle, a gap filling member is provided in a gap between at least one of the pair of regulating members and the rotating member, thereby preventing insertion of an insert into the gap.

  However, in order to prevent the act of holding the rotation ring at a desired rotation position by a foreign substance such as a coin, Patent Document 1 is not sufficient. That is, in order to make the rotation ring rotatable, a gap is always generated between the members, and this gap is opened to the outside of the handle.

  On the other hand, the above-mentioned patent document 2 aims to fill the gap almost completely by the gap filling member. For this reason, it is necessary to make the dimensional tolerances of each part extremely small in the design so that there is no backlash (playing part) between the parts constituting the handle, which not only makes it difficult to manufacture each part. In addition, it is necessary to prevent the assembly error of each part from occurring.

In Patent Document 2, if a foreign object such as a coin can be inserted between one surface of the gap filling member and the regulating member or the rotating member, the other surface of the gap filling member is the rotating member or the regulating member. By being in close contact with the member, the rotating member can be held at a predetermined rotational position.
Therefore, in order to prevent the act of holding the rotation ring at a desired rotation position by a foreign object such as a coin without making the manufacture of each component difficult, further ingenuity is required.

  The present invention has been made in view of such conventional problems, and prevents the act of holding the rotating ring portion at a desired rotating position by a foreign object such as a coin without making it difficult to manufacture each component. It is an object of the present invention to provide an operation handle for a gaming machine that can be used.

The present invention includes a fixed base portion, a turning ring portion for adjusting a launching strength of a game ball by turning around a central axis of the fixed base portion, and turning the turning ring portion to an initial position. In an operating handle for a gaming machine having a biasing member that biases to move,
Between the fixed base portion and the rotation ring portion, a rotation holding prevention member that covers or fills a gap formed between the fixed base portion and the rotation ring portion is disposed. The rotation holding prevention member is rotatable with respect to both the fixed base portion and the rotation ring portion,
The rotation holding prevention member is configured to form a predetermined clearance from the other when the fixed base portion and the rotation ring portion are in close contact with each other and become an integral state. An operating handle for a gaming machine characterized by the above (claim 1).

  In the operation handle for the gaming machine of the present invention, the act of holding the rotation ring portion at a desired rotation position by disposing the rotation holding prevention member between the fixed base portion and the rotation ring portion. Can be prevented. Specifically, the rotation holding prevention member can rotate with respect to both the fixed base portion and the rotation ring portion, and covers a gap between the fixed base portion and the rotation ring portion. Or a shape that fills this gap.

  Then, in order to prevent the player or the like from returning the rotation ring portion to the initial position by the urging member, a foreign object such as a coin is inserted into the gap formed between the rotation holding prevention member and the fixed base portion. When inserted, the foreign object is brought into close contact with the rotation holding prevention member and the fixed base part, but a predetermined gap is formed between the rotation holding prevention member and the rotation ring part. Is done. Therefore, the rotation ring portion can be rotated with respect to the rotation holding prevention member and the fixed base portion that are in the integrated state.

On the other hand, when a foreign object such as a coin is inserted into the gap formed between the rotation holding prevention member and the rotation ring part, the rotation holding prevention member and the rotation ring part are brought into close contact with each other by the foreign object. However, a predetermined gap is formed between the rotation holding preventing member and the fixed base portion. Therefore, the rotation holding preventing member and the rotation ring portion that are in the integrated state can be rotated with respect to the fixed base portion.
Therefore, a player or the like cannot hold the rotating ring portion at a desired rotating position using a foreign object such as a coin, and the operating handle rotates the rotating ring portion with respect to the fixed base portion. It can be kept operational.

  In the present invention, even if a predetermined gap is formed between the fixed base portion and the rotation ring portion, the gap can be covered or filled with the rotation holding prevention member. Therefore, the dimensional tolerance of the predetermined gap can be set gently. Further, when the predetermined holding gap is covered, the rotation holding prevention member plays a role even if it is formed to be slightly larger, and when the predetermined holding gap is filled, the rotation holding prevention member is connected to the fixed base portion or the rotating ring portion. Even if a somewhat large gap is formed between them, it plays the role. Therefore, it is easy to manufacture each part, and even if the width dimension of the gap formed between the rotation holding prevention member and the fixed base part or the rotation ring part varies due to the dimensional tolerance of each part. In order to keep the rotating ring portion rotatable with respect to the fixed base portion, there is almost no trouble.

  Therefore, according to the operating handle for the gaming machine of the present invention, the rotating ring portion is held at a desired rotating position by a foreign object such as a coin without making it difficult to manufacture each part and to assemble the operating handle. Can be prevented.

A preferred embodiment of the present invention described above will be described.
In the present invention, the fixed base portion may be a main body base portion that is fixed to the front panel of the gaming machine. The fixed base portion may be a cap portion that covers the front side of the operation handle. Further, the fixed base part may be the main body base part and the cap part.
Moreover, the said rotation ring part can be integrated with the cap part which covers the front side of the said operation handle.
In addition, the rotation holding prevention member is preferably provided so as to cover or fill the entire circumference of the gap between the fixed base portion and the rotation ring portion. In this case, it is possible to prevent foreign objects from being inserted all around the operation handle.

Moreover, it is preferable that the rotation holding preventing member is made of a material that is hard and has low friction. As the rotation holding prevention member, for example, polyacetal (POM), fluorine-containing polycarbonate (PCF), or the like can be used.
In addition, the width dimension of the gap formed between the rotation holding preventing member, the fixed base portion, and the rotation ring portion is determined by each component (the main body base portion, the rotation ring portion, the rotation holding portion). It can be set in consideration of play (play) caused by dimensional tolerance of the prevention member or the like), assembly error, and the like.

The urging member may be a torsion coil spring provided on a central shaft portion for rotatably supporting the rotating ring portion.
In addition, the amount of rotation operation of the rotation ring portion can be detected by a variable resistor connected to the central shaft portion, and based on the resistance value in the variable resistor, the launch intensity of the game ball is determined. Can be determined.

The fixed base portion and the rotating ring portion are each formed with a protruding portion that protrudes radially outward, and the rotation holding prevention member that covers the gap covers the both protruding portions from the outer periphery. It can have a ring part and a pair of clamping convex parts which protrude inward in the diameter direction of the ring part in a state where the both convex parts are sandwiched in the axial direction (Claim 2).
In this case, the rotation holding prevention member can be stably maintained on the outer periphery of the gap between the fixed base portion and the rotation ring portion.

Further, an annular protrusion is formed on the outer peripheral surface of the fixed base portion at a position facing the entire periphery of the opening portion of the gap formed between the outer peripheral surface of the fixed base portion and the sandwiching convex portion in the ring portion. The outer peripheral surface of the rotating ring portion is opposed to the entire periphery of the opening portion of the gap formed between the outer peripheral surface of the rotating ring portion and the clamping convex portion in the ring portion. It is preferable to form an annular protrusion at the position.
In this case, it is possible to prevent foreign objects such as coins from being inserted from a direction parallel to the direction of the central axis of the fixed base portion.

  The fixed base portion is a main body base portion fixed to the front surface of the gaming machine, and an outer diameter of a rear end portion of the rotating ring portion is larger than an outer diameter of a front end portion of the main body base portion. A step-shaped reduced diameter portion is formed at a front end portion of the main body base portion, and the rotation holding prevention member is formed between an outer periphery of the main body base portion and an inner periphery of the rotation ring portion. A gap is formed between the rotation holding preventing member and the reduced diameter portion of the main body base portion so that the predetermined handle is not exposed to the outside of the operation handle. A gap can also be formed (claim 3).

  In this case, the player or the like can insert a foreign object such as a coin into the gap formed between the rotation holding prevention member and the rotation ring portion, while the rotation holding prevention member and the main body base portion It is difficult to insert foreign objects such as coins into the gap formed between the reduced diameter portion and the outer peripheral portion of the rotation ring portion or the rotation holding prevention member as an obstacle. For this reason, it is possible to always use the rotation holding prevention member and the rotation ring portion to insert and remove the foreign matter, and to stabilize the action of holding the rotation ring portion at a desired rotation position. Can be prevented.

Hereinafter, embodiments of the operation handle for a gaming machine according to the present invention will be described with reference to the drawings.

The rotation holding preventing member 5 </ b> A and the rotation ring portion 3 are configured to be rotatable with respect to the main body base portion 2. 1 and 2, the front side of the gaming machine 10 is indicated by an arrow F.

Hereinafter, the operation handle 1 for the gaming machine of this example will be described in detail with reference to FIGS.
As shown in FIG. 1, the operation handle 1 of this example is arranged to stand forward from a front panel 11 on which a ball tray 12 is arranged in a gaming machine (pachinko gaming machine) 10.
As shown in FIG. 2, the rotating ring portion 3 of this example is integrated with a cap portion 4 that covers the front side of the operation handle 1. The main body base portion 2 of this example is formed as a shaft-like portion and a substantially hemispherical portion that rises forward of the front panel 11. And the operation handle 1 of this example is comprised so that the whole rotation ring part 3 may be rotated with respect to the main body base part 2. FIG.

In addition, the rotating ring portion 3 includes an auxiliary member 41 and a main body base portion 2 that are located inside the rotating ring portion 3 and fixed to the main body base portion 2 with a portion (a rotating plate 34 described later) located inside the rotating ring portion 3. It is comprised so that it may rotate in the state clamped between.
Further, as shown in FIG. 1, a plurality of operation projections 32 capable of locking a player's finger are formed on the outer periphery of the rotation ring portion 3 at appropriate locations in the circumferential direction.

As shown in FIG. 2, in the operation handle 1, a touch sensor 71 for detecting that the player has touched the rotating ring portion 3 or the cap portion 4 is provided. Further, the main body base portion 2, the rotating ring portion 3 and the cap portion 4 are made of synthetic resin, and conductive metal plating is applied to appropriate portions of the surface of the rotating ring portion 3 and the surface of the cap portion 4. It is.
The detection part of the touch sensor 71 is electrically connected to metal plating applied to appropriate portions of the surface of the rotating ring part 3 and the surface of the cap part 4. When the player of the gaming machine 10 (see FIG. 1) is in contact with the metal plating, the player detects the capacitance of the player and detects that the player is in contact with the operation handle 1. can do.

  In the operation handle 1, a torsion coil spring (biasing member) 72 that urges the rotating ring portion 3 in a direction that weakens the launching strength of the game ball (biased toward the initial position) is disposed. Further, a rotation amount sensor 73 for detecting a rotation operation amount of the rotation ring portion 3 is disposed in the operation handle 1. This rotation amount sensor 73 is constituted by a variable resistor, and its detection shaft is connected to a shaft portion 33 connected to the central portion of the rotation plate 34 fixed to the rotation ring portion 3. Then, the control device in the gaming machine 10 operates the ball launching device in the gaming machine 10 in accordance with the rotational operation amount of the rotational ring unit 3 to increase the launch intensity of the game ball to be launched into the game area of the game board. Can be adjusted.

  Further, as shown in FIG. 2, the rotation plate 34 fixed to the rotation ring portion 3 inside the rotation ring portion 3 and the rotation holding prevention member 5 </ b> A have an arc shape at circumferential positions corresponding to each other. Long holes 36 and 56 are formed, and the auxiliary member 41 disposed inside the rotation ring portion 3 is provided with a boss 411 for fixing to the main body base portion 2. Then, due to the engagement structure between the arc-shaped long holes 36 and 56 and the mounting boss 411, the rotating ring portion 3 can be rotated within a predetermined angle range (in this example, within a range of about 100 °). It can be operated manually.

  Although not shown, the operation handle 1 is provided with a stop switch that can stop the launch of the game ball in a state where the rotation ring portion 3 is rotated. This stop switch has an operation part with a tip projecting from the outer peripheral part of the main body base part 2 so as to be operable by a player, and a switch part for detecting an operation state by the operation part.

  Moreover, as shown in FIG. 2, the outer diameter of the rear end part 31 of the rotation ring part 3 is made larger than the outer diameter of the front end part 21 of the main body base part 2, and the rotation ring part 3 of this example is The rear end portion 31 covers the front end portion 21 of the main body base portion 2 from the outside in the radial direction. The front end portion 21 of the main body base portion 2 is formed with a step-shaped reduced diameter portion 211 having a diameter smaller than that of the outer peripheral portion of the main body base portion 2. The rotation holding prevention member 5 </ b> A has a disk shape that fills the entire circumference of the member space 61 </ b> A formed between the outer periphery of the main body base portion 2 and the inner periphery of the rotation ring portion 3.

An inner opening clearance 62A between the rotation holding prevention member 5A and the main body base portion 2 is formed between a step-like convex portion 52 (to be described later) of the rotation holding prevention member 5A and an outer peripheral surface of the reduced diameter portion 211 of the main body base portion 2. It is formed in a state where it is not exposed to the outside of the operation handle 1.
Further, the outer opening clearance 62B between the rotation holding prevention member 5A and the rotation ring portion 3 is formed to be opened rearward between the rotation holding prevention member 5A and the rotation ring portion 3. . A player or the like can insert a foreign substance C such as a coin into the outer opening gap 62B that opens rearward, while the inner opening gap 62A is exposed to the outside of the operation handle 1 in the inner opening gap 62A. Since the outer peripheral portion (rear end portion) 31 of the rotation ring portion 3 or the outer peripheral portion of the rotation holding prevention member 5A becomes an obstacle, the foreign matter C such as a coin can be inserted. I can't do it.

As shown in FIG. 2, an insertion hole 51 through which the shaft portion 33 connected to the center portion of the rotating plate 34 is inserted is formed at the center portion of the rotation holding prevention member 5 </ b> A. The opening edge portion of the insertion hole 51 is formed in a curved surface shape.
The outer peripheral surface of the rotation holding prevention member 5A is formed in a shape along the inner peripheral surface of the rear end portion 31 of the rotation ring portion 3, and in the vicinity of the outer peripheral surface of the rotation holding prevention member 5A, A step-like convex portion 52 for forming the inner open gap 62A is provided between the main body base portion 2 and the reduced diameter portion 211.

  As shown in the figure, the width dimension X1 of the inner open gap 62A formed between the inner peripheral surface of the step-like convex portion 52 and the outer peripheral surface of the reduced diameter portion 211 of the main body base portion 2 is the width of the outer open gap 62B. It is set larger than the width dimension X2 and the width dimension X3 of the gap 622 formed between the insertion hole 51 of the rotation holding prevention member 5A and the shaft portion 33. As a result, when a foreign object C such as a coin is inserted into the outer open gap 62B, the opening edge of the insertion hole 51 and the outer peripheral surface of the shaft portion 33 are in close contact with each other, thereby preventing the rotation ring portion 3 and the rotation holding prevention. While the member 5A can be securely rotated and fixed (becomes an integral state), the main body base portion 2 and the rotation holding preventing member 5A can be reliably prevented from being rotationally fixed.

  In addition, the outside dimension of the gap 622 formed between the insertion hole 51 of the rotation holding prevention member 5A and the shaft portion 33 is smaller than the width dimension X2 of the outside opening gap 62B, thereby opening the outside. When the foreign object C is inserted into the gap 62B, the opening edge portion of the insertion hole 51 is moved before the outer peripheral surface of the rotation holding preventing member 5A is brought into contact with the inner peripheral surface of the rear end portion 31 of the rotation ring portion 3. The shaft portion 33 can be brought into contact with the shaft portion 33. Thereby, the rotation ring part 3 and the rotation holding prevention member 5 </ b> A in a state where the rotation is fixed can be stably rotated with respect to the main body base part 2.

  In the operation handle 1 for the gaming machine of the present example, the rotation holding portion 5A is disposed between the main body base portion 2 and the rotation ring portion 3 so that the rotation ring portion 3 can be rotated as desired. The act of holding in position can be prevented. Specifically, the rotation holding prevention member 5A can be rotated with respect to both the main body base portion 2 and the rotation ring portion 3, and is formed in a shape that fills the entire circumference of the member space 61A. It is. Opening gaps 62A and B are formed between the rotation holding prevention member 5A and the main body base portion 2 and between the rotation holding prevention member 5A and the rotation ring portion 3, respectively.

  Then, in order to prevent the player and the like from returning to the initial position by the urging member 72, the outer opening gap 62B between the rotation holding preventing member 5A and the rotation ring portion 3 is avoided. When a foreign object C such as a coin is inserted, the rotation holding prevention member 5A and the rotation ring part 3 are brought into close contact with each other by the foreign object C, but the rotation holding prevention member 5A and the fixed base part 2 are integrated. The state in which the inner opening gap 62A is formed is maintained between the two. Therefore, the rotation holding prevention member 5 </ b> A and the rotation ring portion 3 that are in the integrated state can be rotated with respect to the main body base portion 2.

On the other hand, a player or the like cannot insert a foreign substance C such as a coin into the inner opening clearance 62A between the rotation holding preventing member 5A and the main body base portion 2. As a result, the foreign object C can be inserted and fixed in rotation and can always be the rotation holding prevention member 5A and the rotation ring portion 3, and the action of holding the rotation ring portion 3 in a desired rotation position. Can be prevented more stably.
Therefore, the player or the like cannot hold the rotating ring portion 3 at a desired rotating position using the foreign matter C such as a coin. In the operation handle 1, the player can hold the rotating ring portion 3 with the main body base portion 2. The rotation operation can be maintained.

  Further, in this example, even if a predetermined member space 61A is formed between the fixed base portion 2 and the rotating ring portion 3, the member space 61A is filled with the rotation holding preventing member 5A. be able to. Therefore, the dimensional tolerance of the member space 61A can be set gently. Further, when the rotation holding prevention member 5A fills the member space 61A, the above condition (X1) is satisfied even if a somewhat large open gap 62A, 62B is formed between the fixed base portion 2 or the rotation ring portion 3. If it satisfies> X3), it can play its role. Therefore, it is easy to manufacture each component such as the fixed base portion 2, the rotation ring portion 3, and the rotation holding prevention member 5A.

  In other words, in this example, it is not necessary to manage the width dimensions of the open gaps 62A and B in design, and even if the width dimensions of the open gaps 62A and B vary due to the dimensional tolerance of each part, Since the rotation ring portion 3 is maintained so as to be rotatable with respect to the main body base portion 2, there is almost no trouble.

  Therefore, according to the operation handle 1 for the gaming machine of this example, the rotating ring portion 3 can be rotated by a foreign object C such as coins in a desired rotation without making it difficult to manufacture each part and to assemble the operation handle 1. The act of holding in the moving position can be prevented.

(Example 2)
In this example, as shown in FIG. 3, the rotation holding prevention member 5 </ b> B is disposed around the entire circumference of a member gap 61 </ b> B formed between the front end portion 21 of the main body base portion 2 and the rear end portion 31 of the rotation ring portion 3. It is the example formed in the shape covered. In FIG. 3, the front side of the gaming machine 10 (not shown) is indicated by an arrow F.
Specifically, the front end portion 21 of the main body base portion 2 of this example is formed with a main body side convex portion 212 that protrudes radially outward, and the rear end portion 31 of the rotating ring portion 3 of this example. Is formed with a rotation-side convex portion 312 protruding outward in the radial direction.

  Further, the rotation holding prevention member 5B of this example includes a ring portion 53 that covers the main body side convex portion 212 provided on the main body base portion 2 and the rotation side convex portion 312 provided on the rotary ring portion 3 from the outer periphery. The ring portion 53 includes a front-side clamping convex portion 531 and a rear-side clamping convex portion 532 that project radially inward from the axial front end portion and the axial rear end portion. Then, by arranging (pinching) the main body side convex portion 212 and the rotational side convex portion 312 between the front side sandwiching convex portion 531 and the rear side sandwiching convex portion 532, the rotational holding preventing member 5B is It can be stably maintained on the outer periphery of the member gap 61B.

Further, as shown in FIG. 3, the outer peripheral surface of the main body base portion 2 has an opening portion of a rear-side open gap 62 </ b> D formed between the outer peripheral surface of the main body base portion 2 and the rear-side clamping convex portion 532. A main body side annular projection 213 is formed at a position facing the entire circumference at a predetermined interval. Further, the outer peripheral surface of the rotating ring portion 3 is opposed to the entire periphery of the opening portion of the front opening gap 62 </ b> C formed between the outer peripheral surface of the rotating ring portion 3 and the front clamping convex portion 531. A rotating side annular projection 313 is formed at a position where the rotation is performed.
Note that the gap X4 between the main body side annular projection 213 (rotation side annular projection 313) and the outer surface of the rear side clamping projection 532 (front side clamping projection 531) is the main body side projection 212 (rotation). It can be formed larger than the gap X5 between the side convex portion 312) and the inner surface of the rear side clamping convex portion 532 (front side clamping convex portion 531).

In this example, it is possible to prevent the foreign substance C such as a coin from being inserted from a direction parallel to the direction of the central axis L of the main body base portion 2.
Further, in this example, when a foreign object C such as a coin is inserted into the gap X4 between the main body side annular protrusion 213 and the outer surface of the rear side holding convex part 532, the main body side convex part 212 and the rear side holding convex part Although the inner surface of 532 comes into contact with the main body base portion 2 and the rotation holding prevention member 5B, the gap between the rotation-side annular projection 313 and the outer surface of the front-side clamping protrusion 531 is formed. The state where X4 and the gap X5 between the rotation-side convex portion 312 and the inner surface of the front-side clamping convex portion 531 are formed is maintained. Thereby, the rotation ring part 3 can be rotated with respect to the main body base part 2 and the rotation holding prevention member 5A in the integrated state.

Similarly, when a foreign object C such as a coin is inserted into the gap X4 between the rotation-side annular projection 313 and the outer surface of the front-side holding projection 531, the rotation ring portion that is in an integrated state is similarly obtained. 3 and the rotation holding prevention member 5 </ b> B can be rotated with respect to the main body base portion 2.
Further, in this example, even if a somewhat large member gap 61B is formed between the fixed base portion 2 and the rotation ring portion 3, the member gap 61B can be covered by the rotation holding prevention member 5B. Therefore, it is easy to manufacture each component such as the fixed base portion 2, the rotation ring portion 3, and the rotation holding prevention member 5B.
Also in this example, the other configuration of the operation handle 1 is the same as that of the first embodiment, and the same effects as those of the first embodiment can be obtained.

  Also, as shown in FIGS. 4 and 5, the rotation holding prevention member 5 </ b> B has a plurality of front-side clamping protrusions 531 in the circumferential direction R at the front end in the axial direction of the ring portion 53 in order to facilitate manufacture. In some places, it can be formed as a front claw portion 551 to be engaged with the rotation-side convex portion 312. Further, the rear-side clamping convex portion 532 can be formed as a rear-side claw portion 552 that is engaged with the main-body-side convex portion 212 at a plurality of locations in the circumferential direction R at the axial rear end portion of the ring portion 53.

  In order to allow the front claw portion 551 to be easily elastically deformed, a part of the ring portion 53 is cut out from the front end in the axial direction of the ring portion 53 on both sides in the circumferential direction of the front claw portion 551. Thus, the slit 54 can be formed. In addition, in order to allow the rear claw portion 552 to be easily elastically deformed, a part of the ring portion 53 is cut from the axial rear end of the ring portion 53 on both sides in the circumferential direction of the rear claw portion 552. The slit 54 can be formed by lacking.

  In this case, when forming the rotation holding prevention member 5B using the pair of molds, the pair of molds are moved away from each other in the axial direction of the rotation holding prevention member 5B, The rotation holding preventing member 5B can be taken out. Thereby, manufacture of rotation holding prevention member 5B becomes easy.

In this example, when the cap portion 4 is configured as a separate member from the rotation ring portion 3, the rotation holding prevention member 5 </ b> B is fixed integrally with the main body base portion 2. And it can also provide so that the member clearance gap formed between the said rotation ring parts 3 may be covered.
Further, the operation handle 1 shown in the first and second embodiments can be employed in various game machines such as an arrange ball game machine in addition to the pachinko game machine.
Note that the rotation holding prevention member 5B can be omitted over the entire circumference as long as it fulfills its purpose.
