Description

The present invention relates to a pachinko gaming machine having a ball feeding mechanism for stably supplying pachinko balls stored in a saucer to a pachinko ball launching mechanism so as to be fired.

In the pachinko gaming machine, the game is executed by driving the pachinko ball launching mechanism and firing the pachinko ball by the player's active handle operation. The pachinko ball launched from the pachinko ball launching mechanism is guided upward while drawing an arc along the rail and released into the game area. The pachinko balls stored in the upper tray are guided from the upper tray by the flow-down passage and supplied to the pachinko ball launching mechanism. A ball feeding mechanism is disposed at the lowest position of the downflow passage, that is, at a position adjacent to the pachinko ball launching mechanism. The pachinko balls that flow down the downflow passage are sent to a predetermined position on the rail that is launched by the pachinko ball launching mechanism via the ball feeding mechanism. The ball feeding mechanism feeds pachinko balls one by one onto the rail in synchronization with the launching operation of the pachinko ball launching mechanism. Patent Document 1 is shown as an example of a pachinko gaming machine in which such a conventional ball feeding mechanism is disclosed. The ball feeding mechanism disclosed in Patent Document 1 will be described in more detail based on FIGS. 15 and 16.

A launching mechanism 111 is disposed at the lower front position of the gaming machine body. The launch mechanism 111 includes a launch rail 113 fixed to the front surface of the base plate 112, a pachinko ball launch device 114 behind the launch rail 113, and a ball feed unit 115 disposed in a manner overlapping the pachinko ball launch device 114. It is configured. The main body case 116 of the ball feeding unit 115 as a ball feeding mechanism is formed with an introduction port 117 for introducing the pachinko ball that has flowed down the downflow passage into the main body case 116. A solenoid 119 is disposed inside the main body case 116 and is excited in synchronization with the firing operation of the firing mechanism 111 to generate a magnetic force. A substantially fan-shaped lever 120 is supported at a lower position of the solenoid 119 by a swinging shaft 121 formed at the position of the fan. An iron piece 122 as a suction portion is attached to the upper surface of the lever 120. A guide portion 123 having an inclined surface that is lowered rearward (rail side) is formed at a lower right position in FIG. 15 of the lever 120.

When the solenoid 119 is not energized, the lever 120 is placed on the placement portion 124 arranged at the position of the solid line in FIG. 15, that is, the position below the introduction port 117 in the main body case 116. More specifically, it is mounted on the mounting portion 124 by the lower surface of the guide portion 123 of the lever 120. In this state, the interval between the corner portion 125 as the ball holding portion formed on the right side portion of the lever 120 in FIG. 15 and the tip portion 127 of the shelf portion 126 as the projection facing the introduction port 117 is pachinko. Since it is narrower than the diameter of the sphere B, the pachinko sphere B is held by the corner portion 125 and the tip portion 127 and does not fall as shown in FIG. Here, when the solenoid 119 is excited, the lever 120 moves to the position indicated by the broken line in FIG. 15, that is, the position that swings upward, so that the interval between the corner 125 and the tip 127 increases. As a result, the pachinko ball B falls, and further rolls on the inclined guide surface of the guide portion 123 formed on the lever 120 and is sent out onto the launch rail 113.

By the way, in pachinko games, players often play games while drinking drinking water. In some cases, accidentally spilled drinking water on the upper tray. In that case, spilled drinking water may enter the ball feeding unit 115 from the introduction port 117 along the flow path from the upper tray. When such drinking water enters the ball feeding unit 115, the bar 120 and the main body case 116 are contaminated. Here, drinking water with a high sugar content and fruit juice is particularly problematic. This is because these drinking waters tend to become sticky and sticky like the glue with their sugar content as they dries, and if such drinking water spills, it may hinder the operation of the moving parts. In the conventional ball feeding unit 115, especially when the vicinity of the guide portion 123 and the placement portion 124 is contaminated with the infused sugar-rich drinking water, the adhering force of the drinking water accompanying the evaporation of the water causes the solenoid 119 to be bonded. In some cases, the lever 120 may not swing upward despite being excited, or may not be accurately synchronized with the launching operation of the pachinko ball launcher 114 although it swings. The present invention has been made paying attention to such problems existing in the prior art. The purpose is that even if the drinking water that becomes sticky due to drying accidentally spilled into the saucer enters the ball feed mechanism and the lever driven by the excitation of the solenoid is contaminated, the lever The present invention provides a pachinko gaming machine that does not cause problems in swinging.

In order to achieve the above object, according to the first aspect of the present invention, a receiving tray for storing pachinko balls, a downflow passage for flowing down the pachinko balls in the receiving tray toward the rail member, and a pachinko ball flowing down the downflow passage. Is stopped immediately in front of the rail member and a pachinko ball is sent to the rail member one by one in the direction of the rail member, and the pachinko ball sent out from the ball feeding mechanism is guided to the rail member toward the game area. In the pachinko gaming machine provided with a pachinko ball launching mechanism that launches, the ball feeding mechanism includes a front wall in which an introduction port for introducing a pachinko ball that has flowed down the flow-down passage is formed, and a magnetic action portion is provided below. A solenoid that is disposed in the direction of the solenoid, a swing shaft that supports the solenoid so as to swing, a suction portion that is attracted by a magnetic force generated by a magnetic action portion of the solenoid, and the swing And a lever provided with a ball holding portion protruding in a lateral position sandwiching the suction portion between the shaft and the lever, and the lever is located at a predetermined distance from the magnetic action portion. On the mounting portion so that a narrow path smaller than the diameter of the pachinko sphere is formed between the projection formed facing the introduction port and the sphere holding portion to hold the pachinko sphere. And a second state in which the distance between the protrusion and the ball holding portion is greater than the diameter of the pachinko ball by swinging upward by the adsorption operation of the solenoid. The gist of the invention is that the mounting portion is arranged closer to the swing axis than the lower position of the ball holding portion and at the lower surface position of the lever.

In the configuration as described above, in the pachinko gaming machine, the ball feeding mechanism that sends the pachinko ball to the pachinko ball launching mechanism introduces the pachinko ball that flows down the flow passage from the introduction port, and the protrusion in the first state of the lever. Pachinko balls are temporarily held between the ball holding portions. This is because in the first state of the lever, a narrow path is formed in which the distance between the protrusion and the ball holding portion is narrower than the diameter of the pachinko ball. In this first state, since the solenoid is not excited, the attracting portion of the lever is not attracted by the magnetic action portion and is arranged at a predetermined interval. In the first state, the lever is held because the lever is placed on the placement portion. On the other hand, when the solenoid is excited, the lever instantly swings upward with the swing shaft as a base. With the movement of the lever, the distance between the protrusion and the ball holding part increases, and in the second state of the lever, that is, the distance between the protrusion and the ball holding part is greater than the diameter of the pachinko ball. Therefore, the pachinko ball falls on the ball feeding mechanism and is sent to the rail member.

In such a configuration of the ball feeding mechanism, the placing portion that holds the lever in the first state is disposed closer to the swing shaft than the lower position of the ball holding portion and at the lower surface position of the lever. In other words, the ball holding part is arranged at a position to hold the pachinko ball near the introduction port together with the protrusion, but if the drinking water is spilled on the upper tray, the drinking water travels down the flow path and passes from the introduction port. The ball feed mechanism may get into the ball feed mechanism. In this case, the ball holding portion and the protrusion near the introduction port, the pachinko balls held by them, and the members in the ball feeding mechanism arranged at the lower positions thereof are contaminated. In that case, there is a possibility that a malfunction occurs in the operation of the lever due to the adhesive force of the drinking water which becomes viscous as the water evaporates as described above. However, in the present invention, since the placing portion is disposed closer to the swing shaft than the lower position of the ball holding portion, the drinking water does not fall even if dripping down the range where the drinking water reaches, that is, the lower portion that has entered from the introduction port. Since it is in a position deviating from such a range, there is very little possibility of contamination. In addition, since the placing portion is disposed at the lower surface position of the lever, the lever itself serves as a shielding wall having a function of preventing drinking water from being placed on the placing portion, so that the possibility of contamination is reduced.

In order to achieve the above object, in the invention of claim 2, in addition to the structure of the invention of claim 1, the lever has a horizontal portion formed with the suction portion formed on an upper surface and extended substantially horizontally, A main body composed of a hanging part formed with an inclined surface that guides a pachinko ball that is suspended from the horizontal part and introduced into the ball feeding mechanism in the direction of the rail member; The gist is that it is arranged within the range defined by the hanging part. In the lever having such a configuration, the inlet for drinking water to enter is located obliquely above the range defined by the horizontal portion and the hanging portion. In other words, if the placement part is arranged within this range, the introduction part direction into which the drinking water enters is completely protected by the horizontal part and the hanging part, and the placement part may be contaminated. Less. In order to achieve the above object, in the invention of claim 3, in addition to the configuration of the invention of claim 2, an upper position of a fall path of a pachinko ball formed facing the introduction port, The gist is that a shielding wall is formed at a position adjacent to the lever. When drinking water invades from the introduction port vigorously, there is a risk of splashing around. In this way, if the shielding wall is formed at the upper position of the dropping passage and at the position adjacent to the lever, it is possible to shield the splashed droplets from reaching the lever direction.

In order to achieve the above object, in the invention of claim 4, in addition to the configuration of the invention of any one of claims 1 to 3, the upper surface of the mounting portion is substantially the same as the lowermost edge portion of the introduction port. The gist is that it is the same height. When drinking water intrudes from the introduction port, if a large amount of drinking water flows in, it may spread like a waterfall from the introduction port and contaminate a considerable area in the ball feeding mechanism. However, when the upper surface of the mounting portion on which the lever is mounted is substantially the same height as the lowermost edge portion of the introduction port, even if a large amount of drinking water infiltrates, the horizontal position is high. Since there is no possibility of spreading in the direction, there is no possibility of the mounting part being contaminated. Here, the upper surface of the mounting portion is “substantially the same height” as the lowermost edge portion of the introduction port, not only in the case of exactly the same height, but also in a range in which contamination of the mounting portion is reliably prevented. Including meaning.

In order to achieve the above object, in the invention of claim 5, in addition to the configuration of the invention of claim 1, a shield wall projecting in the front-rear direction is formed on the hanging part. This is the gist. If it does in this way, it can be ensured that drinking water does not reach a mounting part. In particular, it is effective in the case where a large amount of drinking water intrudes as described above, or even if the drinking water invades so vigorously that splashes are scattered.

In the inventions described in the above claims, even if spilled drinking water enters the ball feed mechanism and contaminates the inside, there is very little possibility that the drinking water will be applied to the mounting portion that holds the lever. The mounting part is not contaminated, and the mounting part and the lever are not adhered to each other by sticky drinking water, and a malfunction occurs when the lever is attracted and swung by the excitation of the solenoid. There is no end.

A game board mounting space 20 is formed above the lower region 16, and a game board 21 is disposed in the space 20. The space 20 is formed with a window hole 23 that is cut out in a substantially elliptical shape, and the game surface 21 a of the game board 21 is exposed forward from the window hole 23. On the game surface 21a, an outer rail 25 and an inner rail 26 as rail members are mounted to define a game area on the game surface 21a.

A door frame 31 is disposed on the front surface of the main body frame 14. As shown in FIG. 1, the door frame 31 has a rectangular outer shape that is substantially coincident with the outer shape viewed from the front of the main body frame 14. The door frame 31 is attached to the main body frame 14 so as to be openable and closable. A visual window hole 32 is formed in the door frame 31 so that the player can visually observe the game surface 21a. A glass plate 33 supported by a frame (not shown) is disposed on the back side of the door frame 31 at the position of the viewing window hole 32. On the front side of the door frame 31 and on the left and right and above the visual window hole 32, a decorative panel 35 bulging forward is disposed. In the decoration panel 35, a speaker device (not shown) and a decoration lamp (not shown) are arranged. A first bulging portion 36 bulging forward is provided at a position below the visual window hole 32, and an inner side of the first bulging portion 36 is an upper tray 37. The upper tray 37 serves as a ball reservoir for temporarily storing game balls paid out from a payout device (not shown) and guiding them in the direction of the launching mechanism 17 while aligning them in a row.

A second bulging portion 40 bulging to the front side is provided at a position below the first bulging portion 36 in the door frame 31, and the inner side of the second bulging portion 40 is a lower tray 41. . The lower tray 41 stores the pachinko balls distributed by the pachinko ball distribution mechanism unit 18 or auxiliary ball storage for storing the pachinko balls that have flowed down from the upper tray 37 based on the player's active operation. Part. The decorative panel 33, the first bulging portion 36, and the second bulging portion 40 are designed to be unified as a whole. An ashtray 42 is disposed on the left side of the lower tray 41 when viewed from the front. A pachinko ball launching handle 43 is formed on the right side of the lower tray 41 so as to protrude forward.

Next, the launch mechanism 17 will be described in detail. The firing mechanism 17 is a mechanism having a structure for continuously firing pachinko balls in the direction of the game surface 21a based on the player's operation of the handle 43. As shown in FIGS. 2 to 4, the base plate 50 of the firing mechanism unit 17 is fixed to a mounting space 51 in the lower region 16 by bolts 52. On the base plate 50, a launch rail 53, a pachinko ball launcher 54, and a ball feed unit 55 as a ball feed mechanism are respectively attached. The launch rail 53 is disposed on the left shoulder so that the outer rail 25 is connected to the left of the base plate 50 on an extension line in the extending direction. A jump space 48 is provided between the upper end 53 a of the launch rail 53 and the lower base end portion 25 a of the outer rail 25. A pachinko ball that has been fired and the outer rail 25 has been transferred to but has not reached the game surface 21a falls from the jumping space 48 and is guided from the foul ball passage 49 to the lower tray 41. On the right side of the base plate 50, a pachinko ball launcher 54 having a launch solenoid 58 built therein is disposed. The pachinko ball launcher 54 is provided with a launcher 56 that moves forward and backward in accordance with the excitation operation of the launch solenoid 58. The pachinko ball launching device 54 is fixed so that the launching rod 56 rises to the left with respect to the base plate 50 in the same manner as the launching rail 53 so that the extending direction of the launching rail 53 coincides with the advancement and retreating direction of the launching rod 56. Yes. A stopper 57 is disposed at an upper position adjacent to the launch head 56a at the tip of the launching rod 56. The pachinko ball sent out from the ball feed unit 55 onto the launch rail 53 is brought into contact with the stopper 57 and stopped. This stop position is the optimum launch position of the pachinko ball by the launcher 56.

The ball feeding unit 55 is disposed above the firing rail 53 and the pachinko ball launching device 54. As shown in FIG. 6, the ball feeding unit 55 includes a unit main body 60 and a lid 61. As shown in FIGS. 6 and 9A to 9C, the unit main body 60 is composed of four wall surfaces: a front wall 60a, an upper wall 60b, and left and right side walls 60c and 60d. The front wall 60a is cut out in a substantially trapezoidal shape so as not to interfere with the pachinko ball launcher 54 when the ball feeding unit 55 is attached. Since the lid 61 is disposed at a position opposed to the front wall 60a, the ball feeding unit 55 has a box shape with the lower surface opened. In the following description of the ball feeding unit 55, the rear side in FIG. 6 is the front side or the front side, and the front side is the rear side or the back side. Further, the left and right directions in FIGS. 9A to 9C are left and right. Fixing leg members 62 having female screw portions are provided on the rear surface of the front wall 60 a, that is, on the inner side of the unit main body 60, and the solenoid 63 is fixed to the leg member 62 with screws 64. ing. The solenoid 63 has a magnetic core 63a serving as a magnetic action portion exposed downward, and is surrounded by a frame 63b serving as a magnetic action portion. As shown in FIGS. 9A to 9C, the solenoid 63 is fixed in a slightly inclined state so as to rise to the right in the drawing (that is, as viewed from the rear).

A lever 65 is disposed at a lower position of the solenoid 63. The lever 65 is pivotally supported by a rivet 74 as a rocking shaft with respect to a mounting bearing 66 formed on the back surface of the front wall 60a. The lever 65 is basically composed of a horizontal portion 67 extending horizontally from the position of the bearing 66 so as to cross the adjacent position below the solenoid 63, and a hanging portion 68 hanging downward from the front end of the horizontal portion 67. The skeleton is composed. A metal piece 70 made of an iron alloy formed in a rectangular shape is attached to the upper surface of the horizontal portion 67. The drooping portion 68 includes a drooping portion main body 69 having a substantially square cross section and an inclined portion 71 formed outside the drooping portion main body 69. The inclined portion 71 is formed with an inclined surface 71a that descends toward the rear (that is, the base plate 50 side). A first shielding wall 72 is formed on the side surface of the inclined portion 71 closer to the hanging portion main body 69. The first shielding wall 72 is configured to be wider in the front-rear direction than the hanging part main body 69. A small projecting piece 73 is formed as a mounting portion at a position below the horizontal portion 67 of the lever 65. The lever 65 is held at a position slightly spaced from the lower end of the frame 63 b of the solenoid 63 by the lower surface of the horizontal portion 67 being supported by the upper surface of the small protrusion 73. The state in which the lever 65 is placed on the small protrusion 73 corresponds to the first position of the lever 65. Since the lower part of the unit main body 60 is opened, the small protrusion 73 can be directly seen from below. As shown in FIGS. 6 and 10 to 12, a protruding portion 69 a extending in the vertical direction is formed in front of the hanging portion main body 69.

An introduction hole 75 is formed on the right side of the solenoid device 63 on the front wall 60a. A cylindrical introduction passage 76 that also serves as a reinforcement of the introduction hole 75 surrounding the introduction hole 75 is formed on the back surface of the front wall 60a facing the introduction hole 75. As shown in FIGS. 6 and 9 (a) to 9 (c), the introduction passage 76 has a first inclined portion 77 inclined downward and a second inclined portion inclined downward toward the lever 65. An inclined portion 78 is formed. A vertical wall portion 79 is formed downward from the lower end of the second inclined portion 78, and a drop passage 80 in which a pachinko ball falls is formed between the vertical wall portion 79 and the hanging portion 68 of the lever 65. . The introduction passage 76 has a shape in which the direction of the hanging portion 68 of the lever 65 is cut out, and the pachinko ball introduced into the ball feeding unit 55 from the introduction hole 75 is introduced into the introduction passage 76 by the first and second inclined portions 77 and 78. Is guided in the direction of the notch and is guided in the direction of the launch rail 53 from the fall passage 80. The side surface on the lever 65 side of the introduction passage 76 projects rearward to the extent that there is no hindrance to the movement of the pachinko ball in the direction of the fall passage 80 and constitutes a second shielding wall 83. An engaging portion 84 is formed at the rear portion of the introduction passage 76.

A latch piece 85 is formed on the rear surface of the front wall 60a on the left side of the solenoid 63 so as to project rearward. The right wall 60c is formed with two cuts 86 at the top and bottom, and the portion sandwiched between the cuts 86 is a latch piece 87. A pair of upper and lower projecting plates 88 are formed on the outer side of the left side wall 60d, and a rotating pin 89 is suspended from the projecting plates 88. A projection 90 for positioning the door frame 31 projects from the front surface of the front wall 60a.

The lid 61 is composed of four wall surfaces: a rear wall 61a, an upper small wall 61b, and left and right small side walls 61c and 61d. A through hole 91 and an engagement edge 92 are formed at the left position of the rear wall 61a. On the right side of the rear wall 61a, a sealing piece 93 formed in a bowl shape is projected. A pressing piece 94 protruding downward is formed at the lower right position of the rear wall 61a. The latch piece 85 on the unit main body 60 side is engaged with the engagement edge 92 in a state where the lid 61 is mounted on the unit main body 60, and the sealing piece 93 is on the unit main body 60 side as shown in FIG. The leading edge of the sealing piece 93 is engaged with the engaging portion 84 while being fitted behind the introduction passage 76. In this state, as shown in FIG. 9C, the solenoid 63 and the horizontal portion 67 of the lever 65 are sandwiched between the front wall 60a and the rear wall 61a from the front and rear. In addition, as shown in FIG. 9C, the holding piece 94 is disposed behind the upper position of the drop passage 80. The front wall 60a and the rear wall 61a are formed with heat radiation holes 95 at positions facing the solenoid 63, respectively.

Such a ball feeding unit 55 is mounted on the front surface of the unit base 96 disposed at the upper position of the base plate 50. As shown in FIGS. 3 and 4, the unit base 96 is formed with a bearing 97 on which the latch pin 89 is pivotally supported, a through hole 98 and an engagement edge 99 with which the latch piece 87 is engaged. . When the ball feeding unit 55 is set on the unit base 96, the latch piece 87 is engaged with the engagement edge 99. Then, by releasing the engagement relationship between the latch piece 87 and the engagement edge 99, the latch pin 89 can be rotated forward from the set state shown in FIG. 3 as shown in FIG. The latch pin 89 that lifts the ball feed unit 55 upward from the state of FIG. 4 is removed from the bearing 97, and the ball feed unit 55 can be removed from the unit base 96.

Next, in the pachinko gaming machine 11 configured as described above, an operation for setting a pachinko ball to the launch position of the launch rail 53 via the ball feeding unit 55 will be described. When the door frame 31 of FIG. 1 is closed, as shown in FIG. 3, the opening 101 of the flow-down passage 100 that guides the pachinko balls from the upper tray 37 toward the firing mechanism 17 is the front surface of the introduction hole 75 of the ball feeding unit 55. It is arranged in duplicate at the position. Note that one ball feeding operation by the ball feeding unit 55 described below is actually executed in a very short time. 9A and 10A show a state before the pachinko balls are introduced into the ball feeding unit 55. FIG. In this state, the lever 65 in the ball feeding unit 55 is supported by the small protrusion 73 because the solenoid 63 is not excited yet. When the pachinko sphere P is introduced from the introduction hole 75, the pachinko sphere P rolls while being slightly shifted leftward in FIG. 9B by the first and second inclined portions 77 and 78. At this time, since the rear of the introduction passage 76 is sealed by the rear wall 61a of the lid 61, the pachinko ball P does not roll off the introduction passage 76 and jump out of the unit 55. Next, as shown in FIGS. 9 (b) and 10 (b), the pachinko ball P that has rolled is the tip corner portion 102 of the lever 65 (horizontal portion 67), the second inclined portion 78 of the introduction passage 76, and the vertical wall portion. It is temporarily held in the vicinity of the entrance of the fall passage 80 without falling in the direction of the fall passage 80 by the corner portion 103 where 79 intersects. That is, since the gap between the corner portions 102 and 103 is a narrow path smaller than the diameter of the pachinko sphere P, the pachinko sphere P is kept waiting at this position when the solenoid 63 is not excited. In addition, at the standby position, the pressing piece 94 prevents rolling backward.

When the pachinko ball launching device 54 is driven based on the player's operation of the handle 43 in the standby state of the pachinko ball P, the excitation timing of the launching solenoid 58 of the pachinko ball launching device 54 is reached. In synchronization, excitation of the solenoid 63 of the ball feeding unit 55 is started. When the solenoid 63 is excited, the metal piece 70 on the upper surface of the horizontal portion 67 of the lever 65 is attracted by the magnetic core 63a and the lower end of the frame 63b, and the lever 65 swings upward with the position of the bearing 66 as a base. That is, it is separated from the small protrusion 73. Along with this displacement, the space between the two corners 102 and 103 holding the pachinko ball P opens, and the pachinko ball P falls in the direction of the fall passage 80 (the state shown in FIGS. 9C and 10C). . The fallen pachinko ball P is guided by the inclined surface 71 a and sent out on the firing rail 53. Since the excitation time of the solenoid 63 is very short, the lever 65 swings downward by its own weight when the excitation is released, and is again supported by the small projecting piece 73 of FIGS. 9A and 10A. Return. The pachinko ball P following the fallen pachinko ball P is held at the standby position by the lever 65 and the both corners 102 and 103 of the introduction passage 76 which have returned to the original state. The following will be repeated below.

In such a configuration of the ball feeding unit 55, it is assumed that a player accidentally spills drinking water on the upper tray 37. Drinking water flows down the downflow passage 100 and enters the inside through the introduction hole 75 of the ball feeding unit 55. At this time, first, since there is the second shielding wall 83, even if drinking water flows in vigorously, splashing in the direction of the lever 65 is prevented as much as possible. In addition, since the first hanging wall 68 of the hanging part 68 of the lever 65 has a first shielding wall 72, the drinking water flowing down the drop passage 80 is located below the lever 65, that is, in a region defined by the horizontal part 67 and the hanging part 68. It is hard to reach. The small protrusion 73 is directly below the horizontal portion 67 and the upper surface of the small protrusion 73 serving as a contact surface with the horizontal portion 67 is substantially the same as the lowermost edge portion of the introduction hole 75, that is, the first inclined portion 77. Since it is arranged at a height, even if a large amount of drinking water enters, the small protrusion 73 is not contaminated. Further, as shown in FIG. 15, a drooping portion main body 69 and a protruding portion 69 a protruding forward from the drooping portion main body 69 are arranged at a position adjacent to the introduction hole 75 side of the small protrusion 73, so that drinking water further flows. Intrusion in the direction of the small protrusion 73 is prevented. Further, since the ball feeding unit 55 is unitized and is easy to remove, it is also easy to remove the lid 61 from the main body 60.
