Description

  The present invention relates to a ballistic correcting device and a ballistic correcting member in a simulated gun, and a multiple-ballistic-type simulated gun using them, in which rotation is imparted to the bullet in the process of firing a spherical bullet.

  A so-called hop-up technique is applied to a gun that uses a compressed gas or compressed air as a pressure source and fires a spherical bullet commonly called a BB bullet. The above hop-up technology uses the buoyancy generated by applying upward rotation to the spherical bullet, and maintains the straightness of the bullet without increasing the gas pressure, and has the effect of improving the range. Can do. The applicant has been involved in the development of this technology for many years and has been striving for disclosure by filing patent applications successively, starting with JP-A-6-3091. After the above-mentioned application, other companies have proposed Japanese Patent Laid-Open Nos. 6-288697 and 9-42892 for simulated guns.

  On the other hand, for example, Japanese Patent Application Laid-Open No. 5-99594 discloses a technique for firing a plurality of bullets. The invention stops a plurality of bullets by an O-ring having an inner diameter smaller than the outer diameter, and external force is applied at the time of firing. When added, it has a configuration that allows the bullets to pass larger than the outer diameter of the bullets. However, due to the structure that the bullet passes through the O-ring, it seems that it is difficult to put it to practical use, and it seems that it has not been commercialized. Japanese Patent Application Laid-Open No. 2004-324962 discloses a invention of a warhead with a launching device in which a plurality of bullets are fitted in a barrel, but the warhead itself has a firing function, and is actually used for a game gun. It belongs to a special type of gun that is loaded into a bullet launcher.

  All of the above hop-up techniques modify the trajectory of a single bullet, and no gun is known that applies the hop-up technique to all bullets in a gun that simultaneously fires multiple bullets. . The reason for this is that the current hop-up technology has a configuration in which a ballistic correcting member is arranged at the bullet loading position at the rear end of the barrel, that is, the barrel, and one bullet is stopped and stopped by the ballistic correcting member. it is conceivable that. That is, according to the applicant's experiment, the ballistic correction member elastically deforms when the bullet passes through the ballistic correction member that stops the bullet, but the elastic deformation does not completely return when the next bullet passes. It has been confirmed that sufficient rotation cannot be given to the next bullet, and the trajectory of multiple bullets is not constant.

  The present invention has been made in view of the above circumstances, and the problem is that when a plurality of bullets are fired, an equivalent rotation is imparted to all the bullets fired so that the trajectory is substantially constant. It is to be. Another object of the present invention is to provide a ballistic correcting device, a ballistic correcting member, and a multi-ball firing type using the same in a simulated gun capable of giving substantially the same hop-up action to all the bullets fired. Is to provide a simulated gun.

  In order to solve the above-mentioned problems, the present invention provides a barrel for firing a bullet as a ballistic correcting device in a simulated gun that imparts rotation to the bullet in the process of firing a spherical bullet. An upper part of the above-mentioned bullet unit is provided as a ballistic correction unit that is provided at the rear end portion and that can be loaded with a plurality of bullets, and that is contacted in the process in which a plurality of bullets are fired from the bullet unit. The projections are provided so as to protrude slightly inward, and the projections have different heights in the bullet movement direction.

  The simulated gun to which the ballistic correction device of the present invention is applied is assumed to use a spherical bullet commonly called a BB bullet. Moreover, the device of the present invention is in line with the conventional ballistic correcting device in that the bullet is rotated and the ballistic is corrected. However, the present invention is novel in a configuration in which a plurality of bullets are mounted on the rear end of a barrel for firing bullets and a hop-up technique is applied to all the plurality of bullets. The bullet loading part means a bullet loading position, and a plurality of bullets are stopped until receiving a firing pressure at this position.

  In a configuration in which a plurality of bullets are loaded in the bullet loading portion, the present invention is a ballistic correction portion that contacts in the process of firing a plurality of bullets from the bullet loading portion. It shall have the elastic protrusion which was made to protrude and was provided. And the said protrusion has taken the means to assume that height differs in a bullet moving direction. Further, the protrusion satisfies the matter that a plurality of bullets are in contact with each other and the matter that the height differs in the direction of bullet movement. Therefore, the protrusion also serves as a means for stopping and placing until a plurality of bullets receive the firing pressure.

  In the apparatus of the present invention, a plurality of projecting parts made of a resilient material in which a plurality of bullets are in contact with each other are provided with a bullet loading unit capable of loading a plurality of bullets in one barrel for projecting bullets. It is possible to adopt a configuration in which the parts are arranged side by side along the barrel direction on the inside of the bullet loading part. In this configuration, a plurality of bullets are in contact with a plurality of individual protrusions, and it is possible to individually manage the frictional force with respect to the plurality of bullets or the rotation speed of the bullet based on the frictional force. This is a desirable mode.

  The plurality of protrusions arranged in parallel in the barrel direction on the inner side of the loading part are arranged substantially in a row in the barrel direction, and the protrusion height thereof is closer to the muzzle side than the protrusion on the barrel base side. A configuration in which the protrusion is set larger is also desirable for the present invention. The ballistic correction member is elastically deformed by the bullet firing, but as a measure to prevent the elastic deformation from returning completely when the next bullet passes, the force to be received by the next bullet is affected by the protrusion on the barrel base side and the muzzle side protrusion. This is a configuration based on an idea that is given in a plurality of times with a part, and is effective for individual management of the frictional force on the bullet or its rotational speed.

  The trajectory correcting portion has a plurality of front and rear projections, and has a regulator composed of an inclined projection to change the protruding height of the plurality of projections. It is also desirable for the present invention that the contact force of the projecting portion with respect to the bullet in the bullet loading portion is adjusted so as to be adjustable. By moving the adjuster in the front-rear direction, the protrusion moves in the up-down direction and changes the protrusion height of the protrusion, and thus a trajectory correction effect can be obtained. It is clear that the same effect can be obtained even if the regulator itself is directly moved in the vertical direction.

  Further, the present invention is configured as a part of a cylinder having a length that can cover the upper part of a plurality of bullets and a curvature that matches the curved surface of the bullet, and an upper part of the loaded part that is disposed at the rear end of the barrel, A ballistic correcting portion comprising a protrusion provided on the inner surface of the upper portion of the loading portion so that the plurality of bullets arranged on the loading portion at the rear end of the barrel are slightly protruded inward so as to come into contact with each other in the firing process. And a bullet-shaped bullet introduction part that is integrally formed at the upper part and the rear part of the loading part and that has an opening through which a bullet supplied from a magazine passes, and is used in an airtight connection to the rear end part of the barrel. A ballistic correcting member for use in a ballistic correcting device in a simulated gun made of a resilient material.

  The upper part of the bullet loading part and the bullet introduction part are formed in an L shape when viewed from the side, and the rear end of the barrel is formed in a complementary shape that forms a cylindrical bullet loading part in combination with the L shape. In addition, it is desirable that the connection state is maintained by the outer peripheral fixing part when the upper part of the bullet loading part and the bullet introduction part are assembled with the barrel rear end part. The L-shape of the ballistic correction member and the L-shape of the rear end portion of the barrel are combined to form a substantially cylindrical loading portion (a protrusion is present on the upper portion of the cylindrical loading portion). State is maintained.

  Also, as the ballistic correction part, a protrusion that slightly protrudes inward is provided on the upper part of the loading part, and the protrusion consists of a ridge extending in a direction perpendicular to the barrel direction. In order to obtain the above, it is also a desirable aspect to form a recess in the outer surface of the protrusion. A recess can be provided at the position of the outer surface of the bulge of the ridge to reduce the wall thickness, and it becomes possible to obtain the necessary elasticity and to adjust the elasticity.

  Further, in the present invention, in the process of firing a spherical bullet, in order to impart rotation to the bullet at the trajectory correction section, it is possible to load a plurality of bullets provided at the rear end of the barrel for firing the bullet. As a trajectory correction part that comes in contact with a process in which a plurality of bullets are fired from the bullet loading part, it has a protruding part that protrudes slightly inward to the upper part of the bullet loading part, The protrusion includes a ballistic correcting device having a configuration with different heights in the bullet moving direction, and a plurality of bullets can be fired from a plurality of barrels by bundling a plurality of barrels including the ballistic correcting device. A multi-shot type simulated gun configured as described above is included. It is possible to fire at least two bullets from one barrel, bundling two or three barrels, it becomes possible to fire four to six bullets at a time, and all bullets Can be provided with an equivalent hop-up effect.

  Since the present invention is configured and operates as described above, when a plurality of bullets are fired, an equivalent rotation is given to all the bullets fired, and a substantially constant trajectory is obtained. There is an effect of becoming. Further, according to the present invention, a ballistic correcting device and a ballistic correcting member in a simulated gun capable of imparting substantially the same hop-up action to all the bullets fired, and a multi-shot type simulated gun using them Can be provided.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows a multi-shot type simulated gun 10 to which a ballistic correcting device H according to the present invention is applied. The multiple-shot type simulated gun 10 is illustrated as a gas gun having three barrels, and is configured to be able to fire two bullets B from three barrels 14 respectively, and thus a total of six shots simultaneously. .

  In each figure, 11 is a gas gun body, and 12 is a gas source. The gas source 12 communicates with the gas flow path 13 by a vaporized gas extraction cylinder 12a projecting inwardly. The gas flow path 13 is provided in the gas gun body 11, and its end faces the plurality of barrels 14. Is growing. The gas flow path 13 has an air chamber 16 that is opened and closed by a valve body 15 in the middle thereof, and further, a flow rate adjusting unit adjacent to the loading portion 14 a located at the rear end of the barrel 14 downstream. 17. The main body 18 having the air chamber 16 is provided on the gas gun main body 11 side, and a compression spring 19 is disposed between the main body 18 and a nozzle assembly 24 described later.

  The valve body 15 is composed of a shaft-like member, is disposed in the front-rear direction inside the air chamber 16 and penetrates through the front and rear holes 16 a and 16 b, and the front end portion 15 a is a gas flow downstream D of the valve body 15. The road 13 is reached. Further, the rear end portion 15b of the valve body 15 is attached so as to protrude rearward from the rear wall of the air chamber portion 18 and to be movable in the front-rear direction. The front end portion 15a and the rear end portion 15b of the valve body 15 are provided with sealing means 15c and 15d, and the sealing means 15c and 15d seal the air chamber 16 in an airtight manner by contacting the front and rear hole walls. And is biased by the spring 15e in the backward direction of the valve body 15. Therefore, when the valve body 15 moves forward, the gas flow passes through the front hole 16a and flows out from the upstream U of the gas flow path 13 to the downstream D.

  The gas gun main body 11 has a trigger 20, and the trigger 20 is provided to be rotatable around a shaft 20 a, and is configured to open the valve body 15 through a shear 21 and a striker 22 by the operation thereof. ing. The shear 21 is provided so as to be rotatable around a shaft 21 a and has an engaging counterpart 21 b that engages with an engaging portion 20 b provided on the trigger 20. The striker 22 is attached to a guide shaft 23 provided in the gas gun body 11 so as to be movable in the front-rear direction, and is urged forward by a spring 23a. It is comprised so that the edge part 15b may be pressurized. While the trigger 20 and the shear 21 are engaged, the shear 21 is also engaged with the part 22c of the striker 22 at the part 21c, and the striker 22 is placed at the standby position. FIG. 1 shows the moment when the trigger 20 is pulled and the striker 22 strikes the valve body 15. The trigger 20 and the shear 21 are provided with a return spring.

  The flow rate adjusting unit 17 is provided between the gas flow path 13 and the loading portion 14 a of the barrel 14, and the flow rate adjusting unit 17 includes a control valve device 25. The control valve device 25 includes a space 24 that communicates with the gas flow path 13, a gas ejection path 26 that communicates with the space 24 on the upstream side, and communicates with the loading portion 14 a on the downstream side, and a gas ejection path from the space side. 26, and a control valve 27 slidably inserted into 26 (see FIGS. 1 to 3). The gas ejection passages 26 are provided at three places as in the case of the bullet loading portion 14 a, and the control valve 27 is urged in the valve closing direction by the coil spring of the urging means 28 disposed inside each, and is upstream of the space 24. Is stopped against the stop portion 24a. The portion constituting the flow rate adjusting unit 17 has a gas injection nozzle 17a at the tip, and is provided so as to be movable in the front-rear direction with respect to the gas gun body 11, and constitutes a part of a bullet loading mechanism. doing.

  The control valve 27 has a hollow cylindrical structure that is open on the barrel side and substantially closed on the upstream side, and has a side opening 27a and a small end surface as ventilation means for allowing gas to pass through an intermediate portion of the cylindrical structure. And an opening 27b (see FIGS. 2 and 3). The control valve 27 is urged by the urging means 28 in the upstream direction of the gas flow path 13 as described above, but is received by the stop portion 24a in a state where the gas from the gas source 12 does not flow, and the opening portion 27a. Gas is allowed to pass through and can be moved downstream by the gas flow. Accordingly, even when the control valve 27 enters the gas ejection path 26 to a part of the opening 27a with the bullet firing, and the flow of the gas flowing into the barrel is restricted, the small amount of gas is small. It can pass through the opening 27b.

  Since the gas gun 10 is a three-barrel type, the gas flow path 13 may be opened at the center of the space 24 of the flow rate adjusting unit 17. This space 24 has an area including three gas ejection passages 26, and reaches three barrels 14 through three gas ejection passages 26 that are evenly arranged outward from the center thereof. (FIGS. 1 and 2). Therefore, the space 24 of the flow rate adjusting unit 17 is a part that divides the gas flow into the three barrels 14. On the other hand, the spherical bullet B is supplied from the cartridge 30 mounted on the lower part of the gas gun body 11 to the bullet loading portion 14 a side of the barrel 14. In the illustrated example, the bullet B is introduced from the tip of the bullet passage 29 of the cartridge 30 into a bullet feeding chamber 31 whose cross-sectional shape is formed in a triangle or a trident (see FIG. 4).

  The bullet feeding chamber 31 is provided on the gun body side, and a bullet defining member 32 is arranged in a state of being urged in the direction of the bullet passage by the urging means 33, and the bullet B which is about to enter the bullet passage 29 is provided. Is placed in a stopped state by hitting a rocking member 34 provided so as to be movable up and down in order to enter and exit the bullet passage 29. Therefore, in a state where the swinging member 34 is detached downward from the bullet passage 29 and the bullet B is pressed by a spring device (not shown), when the bullet B enters the bullet passage 29, the swinging member 34 is finally swung. It is pushed by the tip 34a of the moving member 34 and distributed to the left and right. The bullet B is pressed by the swing member 34 and guided to the bullet feeding chamber 31 following the loading portion 14a by the shape of the bullet contact portion 32a of the bullet defining member 32 (FIG. 4B). The invention of the multiple barrel mounting apparatus of Japanese Patent No. 3045984 owned by the present applicant is applied to this mounting mechanism.

  The loading portion 14a is disposed at the rear end portion of the barrel that fires the bullet B, and has a size that allows a plurality of bullets B to be placed side by side. Since the bullets B are arranged in a straight line in the front-rear direction, the size of the plurality of bullet loading portions 14a is substantially equal to the length of the two bullets B in the embodiment. The bullet loading unit 14a is provided with a trajectory correction unit 35 that contacts the plurality of bullets B in the process of being fired from the bullet loading unit 14a. The minimum requirement necessary for the trajectory correcting portion 35 is to have a protruding portion 36 that protrudes slightly inwardly on the upper portion of the loading portion 14a, and the protruding portion 36 has a height in the direction of bullet movement. Two points of difference.

  As described above, it is natural that various forms can be adopted as the protrusion 36. Further, as a method of providing the protrusions 36 with different heights, a plurality of the protrusions 36 are provided and bullets are arranged on each of the protrusions 36. There are two possible ways of placing Several methods are conceivable for providing the trajectory correcting portion 35 at the rear end of the barrel. In the present invention, the method using the trajectory correcting member 37 is first adopted.

  The ballistic correcting member 37 is configured as a part of a cylinder having a length capable of covering the upper part of the plurality of bullets B and a curvature matching the curved surface of the bullets B, and is mounted at the rear end of the barrel. It includes a top part 38 and a short cylindrical bullet introduction part 39 having an opening 39a through which the supplied bullet B passes, and is formed integrally with the top part 38 and the rear part. The front and rear two protrusions provided on the inner surface of the upper part 38 are slightly protruded inward so that a plurality of bullets B arranged on the rear part 14a at the rear end of the barrel come into contact with each other in the firing process. The trajectory correcting section 35 including the sections 36-1 and 36-2 is provided (see FIGS. 5 to 8).

  The ballistic correction member 37 in the illustrated embodiment is made of a resilient material and is used in an airtight connection to the rear end of the barrel. For this reason, the upper portion 38 of the loading portion and the bullet introduction portion 39 are viewed from the side. Are formed in an L shape, and the barrel rear end portion formed in a complementary shape with the L shape is combined to form a cylindrical loading portion 14a. In order to stabilize the bullet B, the ratio of the complementary shape of the barrel 14 is larger than that of the substantially L-shaped ballistic correction member 37 (see FIG. 8, particularly B), so that at least half of the diameter of the bullet B fits. Is set to

  When the ballistic correction member 37 is assembled with the rear end of the barrel, the outer periphery fixing portion 40 maintains the connection state, and a substantially cylindrical mounting portion 14a is formed therein. The outer periphery fixing portion 40 is made of a rigid material, and the outer shape of the ballistic correction member 37 made of an elastic material is made constant so that only the protrusion 36 is deformed. Therefore, the connecting portion is in an airtight state. To be kept. The gas injection nozzles 17a are respectively disposed in the openings 39a through which the bullets B pass, and the bullets B supplied to the bullet feeding chamber 31 are pushed out and sequentially loaded into the loading chamber 14a. it can.

  The projecting portions 36 (36-1, 36-2) constituting the trajectory correcting portion 35 are provided so as to slightly protrude inwardly at the upper portion of the loading portion 14a, and extend in a direction perpendicular to the barrel direction. (See FIGS. 6 and 8C). Since the protrusion 36 is a horizontally long protrusion such as a string traversing the circumference, the bullet D can be reliably brought into contact with the protrusion 36. Since the protrusion 36 is too thick as it is, the recess 41 (41-1, 41-2) is formed on the outer surface of the protrusion, and the elasticity necessary for the trajectory correcting part 35 is obtained (FIG. 7, see FIGS. 8A and B). This elasticity acts in proportion to the frictional force imparted to the bullet D, and thus in proportion to the number of revolutions, and is thus one means for adjusting the hop-up action by changing the thickness or the material of the resilient material.

  As shown in detail in FIG. 9, the front protrusion 36-1 has a height h1, and the rear protrusion 36-2 has a lower height h2 (h1> h2), thus For the spherical bullet B, the front protrusion 36-1 gives a larger contact pressure than the rear protrusion 36-2. Further, the front protrusion 36-1 has a length l1 at the top thereof that is longer than a length l2 of the rear protrusion 36-2, and its width b1 is smaller than the width b2 of the rear protrusion 36-2. The projection 36-1 is more easily elastically deformed than the rear projection 36-2. Changing this setting is also a means of adjusting the hop-up effect. If it is possible to apply a friction force of 100 to the front bullet at the front protrusion 36-1, the rear bullet has about 30% friction at the rear protrusion 36-2 when fired three times. A force is applied, and a frictional force of about 70% is applied at the front protrusion 36-1, and the total is 100. In addition, when the six shots are fired, about 40% frictional force is applied to the rear protrusion 36-2, and about 60% frictional force is applied to the front protrusion 36-1, so that the total is 100. The above numerical values are based on the conditions of the embodiment, and may vary depending on conditions such as the initial speed of the bullet to be fired (generally, the low speed is more likely to rotate), the weight of the bullet, the winter season and the summer season. The ratio of the frictional force is an example, and can be arbitrarily changed in actual design.

  As described above, the method of arranging the bullets B at different positions in the front and rear of one inclined projection 36 can be used as a method of providing the projections 36 (36-1, 36-2) with different heights. It is as follows. Therefore, this will be described as Example 2 of the present invention. One inclined projecting portion 36 is set so as to protrude greatly at the front (downstream) in the bullet movement direction and to protrude small at the rear (upstream). (See FIG. 10). Although the degree of inclination in the embodiment of Example 2 is constant before and after, the inclination may be different between front and rear. The other configuration may be the same as that of Example 1 described so far, and detailed description thereof will be omitted.

  The effect | action of this invention comprised in this way is demonstrated with operation | movement of a simulation gun. When the trigger 20 is operated, the shear 21 rotates, the striker 22 is urged by the spring 23a to strike the valve body 15, and the valve body 15 is opened (FIG. 1 shows a state immediately before opening the valve). Since the gas has already flowed into the air chamber 16, the valve 24 opens from the hole 16 a on the outer periphery of the valve body 15 to the space 24 of the flow rate adjusting unit 17 downstream of the gas flow path 13 and the opening of the control valve 27. 27a passes through the gas ejection path 26 and is ejected to all of the bullet loading portions 14a, and the high-pressure gas flow acts on all the bullets B loaded in the bullet loading chamber 14a to fire them. The above firing process is exactly the same in Example 2 with reference to FIG.

  In the apparatus of the present invention, when a plurality of bullets B are loaded on a single barrel 14 that fires bullets, and the plurality of bullets B are fired, the front bullets have a predetermined friction on the projection 36-1. The rear bullets are in contact with a plurality of protrusions 36 (36-1, 36-2) to obtain the same frictional force as the front bullets, and each is given a constant rotation. Is fired from the barrel 14. In the example 2 of FIG. 10, a plurality of bullets are in contact with the inclined projections 36 and are held by the loading unit 14a in a state of different protruding heights. It will be in the same state as touching. That is, if the projecting part (36-1 in the case of two) is elastically deformed by the firing of the bullet and receives the force F1, as a countermeasure against the elastic deformation not returning completely when the next bullet passes. , F2 is the first force that the next bullet receives from the rear protrusion (36-2 in the case of two), and f is the force that is received from the front protrusion (36-1 in the case of two) the second time. The resultant force F2 + f applied in two steps is set to be the same as the force F1 received in the previous stage. Therefore, as in Example 1, the frictional force with respect to a plurality of bullets or the number of bullet rotations based on the frictional force is individually managed, and each bullet is fired from the barrel 14 with a given rotation.

  The bullets B to be fired are loaded in the bullet loading part 14a. In the loaded state in the embodiment, a total of six shots are loaded into each of the three barrels 14, and each bullet B is placed at two front and rear positions. The projections 36-1 and 36-2 provided are held in contact with each other. When these bullets B are fired, a predetermined frictional force is applied to the front bullet B by the front protrusion 36-1, and the rear protrusion 36-2 and the front protrusion are applied to the rear bullet B. With the sum of 36-1, the same frictional force as on the front bullet B acts. Therefore, a substantially constant frictional force can be applied to all six bullets to give a hop-up action. The experiment conducted by the present applicant was carried out under the conditions that the gas pressure was within the specified range, the initial speed was 80 m / s for three shots, the initial speed was 68 m / s for six shots, and the temperature was room temperature. When bullet B was fired at a target 20 meters ahead, it was confirmed that it averaged in a range of about 25 centimeters in diameter at the time of 3 and 6 shots. This experiment did not change no matter how many times, and it was confirmed that the ballistic correction effect of the present invention is excellent.

  As described above, the trajectory correcting device of the present invention can also adjust the hop-up action, and this will be described next as Example 3 of the embodiment according to the present invention. Example 3 of the embodiment is shown in FIG. 11 and the following, and is shown as an example of one barrel 14. Similarly to Example 1, the ballistic correcting member 43 is configured as a part of a cylinder having a length that can cover the upper part of the plurality of bullets B and a curvature that fits the curved surface of the bullets B. Two protrusions 44 (44-1 and 44-2) are provided in front and rear, which are protruded from each other (see FIG. 12). In order to reduce resistance, the protrusions 44 (44-1, 44-2) are provided with small rolls 44a, 44b.

  The ballistic correction member 43 is maintained in a connected state by the outer peripheral fixing portion 45 when assembled with the rear end portion of the barrel, and is adjusted by an inclined protrusion provided inside the adjustment member 46 at a part of the upper portion thereof. The child 46-1, 46-2 has a gap space 45a in which the child 46-1, 46-2 is arranged to be movable in the front-rear direction. The adjustment member 46 is provided so as to surround the outer periphery of the ballistic correction member 43, and is disposed in a part of the space 45a so as to be movable in the front-rear direction, and is provided with a long hole 46a in the front-rear direction formed in the movable piece. The protrusions 44-1 and 44-2 are adjusted in height by being guided back and forth by a shaft 11a provided on the gun body side (see FIG. 11B). A small protrusion 46b is provided on the movable piece of the adjustment member 46, and the amount of adjustment in the front-rear direction is determined within the range of the rack teeth 11b that mesh with the small protrusion 46b. An adjustment lever 46c is exposed to the outside through a slit 11c on the side of the gun body.

  Therefore, by moving the adjustment lever 46c back and forth, the adjusters 46-1 and 46-2 including the inclined protrusions are moved to the two front and rear protrusions 44 (44-1 and 44) via the small rolls 44a and 44b. -2), the contact amount with respect to the bullet B loaded in the loading portion 14a can be changed. The frictional force applied to the bullet B can be adjusted by changing the contact force, and therefore, the amount of rotation applied to the bullet, that is, the hop-up can be adjusted. As described above, according to the present invention, the plurality of protrusions 36 and 44 arranged in parallel in the barrel direction are arranged substantially in a row in the barrel direction, and the protrusion height thereof is set to the protrusion on the barrel base side. The hop-up characteristic can be variously set and adjusted based on the configuration in which the muzzle-side protrusion is set to be larger than the protrusion.
