Description

Description A HOLE BOBBER FOR FISHING

Technical Field

[1] The present invention relates, in general, to holed bobbers for fishing and, more particularly, to a holed bobber which can be easily replaced with another without cutting a fishline to which tackle is coupled, and in which, when head parts of a rotating pipe and a inner pipe which are exposed outside upper and lower ends of the holed bobber are rotated by the hand of a user, slots of the inner pipe and the rotating pipe are aligned with or misaligned from both a slot of an outer pipe, fastened to a bobber body, and a slot of the bobber body, so that the fishline is easily removably inserted into the inner pipe installed along a central axis of the bobber body, and in which, even if the elastic fishline, which is placed in the bobber body, is biased towards a slot of the bobber body, mountain-shaped uneven parts of cushion pads push the fishline into the inner pipe, so that, when the inner pipe is rotated, the fishline can stably maintain its position in the inner pipe, and in which the two cushion pads disposed in the slot of the bobber body prevent water from entering the bobber body and, as well, prevent the bobber body from rotating due to water currents, and in which a ring-shaped chemical light is provided in a concave seat formed in a circumferential outer surface of a neck part or a head part, so that, when fishing at night, in whichever position the holed bobber is placed, the ring-shaped chemical light is horizontally oriented and lights up the surface of the water, thus making it possible for the user to easily observe movement of the holed bobber to see if fish are taking the bait, and in which, when casting, the fishline, which is flying away along with the holed bobber, is prevented from becoming entangled with the ring-shaped chemical light. Background Art

[2] Conventional holed bobbers having slots were proposed in Korean Utility Model

Laid-open Publication No. 1995-31859 (title: center-holed bobber) and Korean Utility Model Registration No. 316185 (title: holed bobber for fishing).

[3] In the center-holed bobber of Korean Utility Model Laid-open Publication No.

1995-31859, a locking pin is provided on each of the upper and lower ends of a bobber body, which has a guide hole formed along a central axis thereof. The bobber body is made of lightweight wood, ABS resin or lightweight plastic. A slot which has a width of approximately 1 mm is formed in the bobber body. The slot communicates with the guide hole and extends to an outer surface of the bobber body. A receiving space in which a sinker is installed is defined at a lower position in the bobber body.

[4] The sinker is made of lead. A guide hole, having the same inner diameter as that of the guide hole of the bobber body, is formed through the sinker. A slot, having the same width as that of the slot of bobber body, is formed in the sinker. The slot of the sinker communicates with the guide hole of the sinker and extends to the outer surface thereof. The sinker is received in the receiving space of the bobber body such that the slot of the sinker corresponds to the slot of the bobber body. At this time, the guide hole of the bobber body communicates with the guide hole of the sinker.

[5] Each locking pin is made of ABS resin. A through hole is formed at a central position through each locking pin. Furthermore, each locking pin includes an insertion part which has an outer diameter slightly larger than the inner diameter of the bobber body, and a flange part which is provided on a circumferential outer surface of the insertion part. A slot, which extends from a predetermined position of the outer surface of the locking pin to the through hole, is formed throughout the overall length of the locking pin.

[6] To couple the center-holed bobber having the above-mentioned structure to a fishline for fishing, the fishline, to which tackle is mounted at an end thereof, is inserted into the through holes of the two locking pins through the slots while the locking pins are oriented such that the flange parts face outwards. The fishline is inserted into the guide hole of the bobber body through the slot thereof such that the bobber body is coupled to the fishline between the two locking pins.

[7] Thereafter, the insertion parts of the locking pins are inserted into the guide hole at the opposite ends of the bobber body until the flange parts thereof are brought into contact with the bobber body. Because the outer diameter of each insertion part is slightly larger than the inner diameter of the guide hole of the bobber body, the locking pin is prevented from being removed. Here, when the locking pins are mounted to the bobber body, the slots of the locking pins must be misaligned from the slot of the bobber body.

[8] To remove the center-holed bobber from the fishline, the user holds the flange part of each locking pin using his/her fingernails or the like and pulls out the locking pin from the bobber body. Subsequently, the fishline which has been placed in the through holes of the locking pins are removed from the locking pins through the slots. Thereafter, the fishline is also removed from the guide hole of the bobber body through the slot thereof.

[9] As such, the center-holed bobber can be coupled to or removed from the fishline, to which the tackle is coupled, without cutting the fishline. In other words, because it is not necessary to cut the fishline when the center-holed bobber is coupled to or removed from the fishline, there is a time-saving advantage.

[10] However, in the prior art, when it is desired to couple the center-holed bobber to a fishline, after the fishline is first inserted at upper and lower positions thereof into the two locking pins, the two locking pins coupled to the fishline must be forcibly fitted into the guide hole of the bobber body through separate processes while a part of the fishline which is placed between the locking pins is inserted into the guide hole of the bobber body. Accordingly, the process of coupling the center-holed bobber to the fishline is complex and inconvenient for the user. Furthermore, there is a problem in that the fishline is undesirably twisted by rotation of the bobber when the water current strikes the sloted part of the bobber.

[11] Furthermore, when it is desired to remove the center-holed bobber from the fishline, if the user holds the flange part of each locking pin using his/her fingernails or the like and pulls out the locking pin from the bobber body, there is some danger of the fingernails being damaged because the two locking pins are forcibly fitted into the guide hole of the bobber body. As such, this art is problematic in that the process of removing the two locking pins is difficult and unreasonable and there is a possibility of bodily harm during the removal process.

[12] Meanwhile, the holed bobber for fishing of Korean Utility Model Registration No.

316185 includes a bobber body, with a hole having a predetermined diameter vertically formed along a central axis through the spherical bobber body, and a slot having a predetermined width formed in the bobber body and extending from the vertical hole to the outer surface thereof. The holed bobber further includes a fishline guide rod which is fitted into the hole and has a fishline guide hole therethrough. Furthermore, the fishline guide rod is slitted at one side thereof from one end to the other end thereof into a width corresponding to the width of the slot of the bobber body, such that the fishline guide hole formed in the fishline guide rod is exposed to the outside. A threaded part is provided on each of the hole of the bobber body and the fishline guide rod, such that the threads correspond to each other. Thus, the fishline guide rod is fitted into the bobber body so as to be rotatable by a handle key such that the fishline guide hole of the fishline guide rod is selectively aligned with or misaligned from the slot of the bobber body.

[13] However, this holed bobber is problematic in that the fishline guide hole may be undesirably aligned with the slot by rotation of the guide rod while fishing so that the bobber body is detached from the fishline. Furthermore, because the separate handle key is required to align or misalign the fishline guide hole of the fishline guide rod with or from the slot of the bobber body, the fishline guide rod rotating process inconveniences the user. As well, there is a problem in that the fishline is twisted by rotation of the bobber when the water current strikes the sloted part of the bobber.

[14]

Disclosure of Invention Technical Problem

[15] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a holed bobber in which slots through which a fishline passes are opened or closed by a simple process in which a user rotates exposed head parts of a rotating pipe and a inner pipe using one hand, so that the fishline can easily be removably inserted into the holed bobber without cutting the fishline to which tackle is coupled, and

[16] in which even if the elastic fishline, having entered the bobber body, is biased towards a slot of the bobber body, mountain-shaped uneven parts of cushion pads push the fishline into the inner pipe, so that, when the inner pipe is rotated, the fishline can stably maintain the position thereof in the inner pipe, and in which the two cushion pads disposed in the slot of the bobber body prevent water from entering the bobber body, prevent the bobber body from rotating due to water currents, and prevent the slots from being undesirably opened during fishing, and in which a ring-shaped chemical light is provided in a concave seat formed in a circumferential outer surface of a neck part or a head part, so that, when fishing at night, in whichever position the holed bobber is placed, the ring-shaped chemical light is horizontally oriented and lights up the surface of the water, thus making it possible for the user to easily observe movement of the holed bobber to see if fish are taking the bait, and in which, when casting, the fishline, which is flying away along with the holed bobber, is prevented from becoming entangled with the ring-shaped chemical light. Technical Solution

[17] In order to accomplish the above objects, the present invention provides a holed bobber for fishing, including: a bobber body, with a guide hole vertically formed through a central axis of the bobber body, and a slot communicating with the guide hole and formed at a predetermined position in the bobber body. Locking grooves are formed throughout the overall length of the bobber body at opposite positions in an inner surface of the guide hole. Each locking groove is spaced apart from the slot at a right angle. An outer pipe is inserted into the guide hole and locked to the locking grooves. The outer pipe includes: an insertion pipe part, with insertion protrusions provided at opposite positions on an outer surface of the insertion pipe part; and a head part provided on an upper end of the insertion pipe part and stopped to an upper end of the bobber body. A slot is formed throughout the entire length of both the insertion pipe part and the head part, a rotation guide slot extends in a horizontal direction and is formed at a predetermined position in a lower part of the insertion pipe part, and a locking hole and a release hole are formed in the insertion pipe part above the rotation guide slot in the same horizontal line and spaced apart from each other by a pre- determined angular interval so that an elastic protrusion of the inner pipe is locked to the locking hole or the release hole. A lower sinker is provided under a lower end of the bobber body. The lower sinker has: a through hole into which the inner pipe is inserted; a slot corresponding to the slot of the outer pipe; and locking notches formed at upper positions in the lower sinker so that a lower end of the outer pipe is inserted into the locking notches. The inner pipe is inserted upwards into the outer pipe through the through hole of the lower sinker and is disposed throughout the overall length of the outer pipe. The inner pipe includes a head part and an insertion pipe part, with a slot formed throughout the entire length of both the insertion pipe part and the head part, a rectangular hole longitudinally formed through the inner pipe, an elastic part provided in a medial portion of the insertion pipe part at a position opposite the slot and slitted at opposite sides thereof, the elastic protrusion provided at a central position on an outer surface of the elastic part, a locking hole formed in an upper part of the insertion pipe part at a position opposite the slot so that a locking protrusion of a rotating pipe is locked to the locking hole, and a rotation guide protrusion provided on an outer surface of the insertion pipe part at a position corresponding to the rotation guide slot of the outer pipe so that movement of the rotation guide protrusion is guided by the rotation guide slot. The rotating pipe is inserted into the upper end of the outer pipe. The rotating pipe includes: a rectangular body inserted into the rectangular hole of the inner pipe inserted into the outer pipe; and a head part provided on an upper end of the rectangular body and stopped to the head part of the outer pipe. A slot is formed in the rotating pipe throughout the entire length of both the rectangular body and the head part in a same direction as the inner pipe, and a locking protrusion is provided on the rectangular body at a position opposite the slot so that the locking protrusion is locked to the locking hole of the inner pipe. Two cushion pads, each having a mountain- shaped uneven part therein, are inserted into the slot. As other embodiments, a neck part may be formed around the upper part of the bobber body, so that a ring- shaped chemical light is fitted over the neck part, or, alternatively, a concave seat may be formed around an outer surface of the head part of the outer pipe, so that a ring- shaped chemical light is fitted over the concave seat.

Advantageous Effects

[18] In a holed bobber for fishing according to the present invention, because slots through which a fishline passes are opened or closed by a simple process in which a user rotates exposed head parts of a rotating pipe and a inner pipe using one hand, so that the fishline can easily be removably inserted into the holed bobber without cutting the fishline to which tackle is coupled. Furthermore, even if the elastic fishline, having entered the bobber body, is biased towards a slot of the bobber body, mountain-shaped uneven parts of cushion pads push the fishline into the inner pipe, so that, when the inner pipe is rotated, the fishline can stably maintain the position thereof in the inner pipe. As well, two separate cushion pads disposed in the slot of the bobber body prevent water from entering the bobber body and prevent the bobber body from rotating due to water currents.

[19] In addition, an elastic protrusion, a locking hole and a release hole, which function to maintain the opened or closed state of the slots, are provided in the holed bobber of the present invention, thus preventing the slots from being undesirably opened during fishing. Moreover, a ring-shaped chemical light is provided in a concave seat formed in a circumferential outer surface of a neck part or a head part, so that, when fishing at night, in whichever position the holed bobber is placed, the ring-shaped chemical light is horizontally oriented and lights up the surface of water, thus making it possible for the user to easily observe movement of the holed bobber to see if fish are taking the bait. Furthermore, when casting, the fishline, which is flying away along with the holed bobber, is prevented from becoming entangled with the ring-shaped chemical light. Brief Description of the Drawings

[31] Hereinafter, a holed bobber of the present invention will be described in detail with reference to FIGS. 1 through 11.

[32] In a first embodiment of the present invention shown in FIGS. 1 through 9, a guide hole 11 is vertically formed through a bobber body 10. A slot 12, which communicates with the guide hole 11, is formed at a predetermined position in the bobber body 10. Locking grooves 13 are formed throughout the overall length of the bobber body 10 at diametrically opposite positions in an inner surface of the guide hole 11, and each locking groove 13 is spaced apart from the slot 12 at a right angle.

[33] Furthermore, an outer pipe 20 is inserted into the guide hole 11 such that it is not rotatable. As shown in FIGS. 1, 4 and 5, the outer pipe 20 includes a head part 22 which is provided on an upper end of an insertion pipe part 21, which is inserted into the guide hole 11, throughout the entire piece thereof. The head part 22 is stopped to an upper end of the bobber body 10. A slot 23 is formed throughout the entire length of both the insertion pipe part 21 and the head part 22, and has the same width as that of the slot 12 of the bobber body 10. Insertion protrusions 25 are provided at diametrically opposite positions on an outer surface of the insertion pipe part 21, and each of the insertion protrusions 25 is spaced apart from the slot 23 at a right angle, so that the outer pipe 20 is locked in the bobber 10 by the insertion protrusions 25 which are inserted into the locking grooves 13 of the bobber body 10.

[34] As shown in FIGS. 1, 4, 8 and 9, a rotation guide slot 26, which extends from the slot 23 to a position adjacent to one insertion protrusion 25, is horizontally formed at a predetermined position in a lower end of the insertion pipe part 21. A locking hole 27 and a release hole 28 are formed in the insertion pipe part 21 in the same horizontal line above the rotation guide slot 26 and are spaced apart from each other by a predetermined angular interval, so that an elastic protrusion 36 of an inner pipe 30 is locked to the locking hole 27 or the release hole 28.

[35] As shown in FIGS. 1 and 4, a lower sinker 40 is provided under a lower end of the bobber body 10. The lower sinker 40 has a through hole 42, which has the same inner diameter as that of the insertion pipe part 21, and a slot 43, which has the same width as that of the slot 23. Locking notches 41 are formed at diametrically opposite positions in the inner surface of the lower sinker 40. Thus, a lower ends of the outer pipe 20 having the insertion protrusions 25 is inserted into the lower sinker 40.

[36] Furthermore, as shown in FIGS. 1, 4 and 5, the inner pipe 30 is inserted upwards into the outer pipe 20 through the through hole 42 of the lower sinker 40 and is disposed throughout the overall length of the outer pipe 20.

[37] The inner pipe 30 includes a head part 32, which is provided on a lower end of an insertion pipe part 31, which is inserted into the outer pipe 20 throughout the overall length thereof. The head part 32 is stopped to the lower sinker 40. A slot 33, which is narrower than the slot 23 of the outer pipe 20, is formed throughout the entire length of both the insertion pipe part 31 and the head part 32. A rectangular hole 38 is longitudinally formed through the inner pipe 30. An elastic part 35, which is defined by two slits 34, is provided in the medial portion of the insertion pipe part 31 at a position opposite the slot 33. The elastic protrusion 36 is provided at a medial position on an outer surface of the elastic part 35. A locking hole 37 is formed in an upper end of the insertion pipe part 31 at a position opposite the slot 33, so that a locking protrusion 54 of a rotating pipe 50 is locked into the locking hole 37. A rotation guide protrusion 39 is provided on the outer surface of the insertion pipe part 31 at a position corresponding to the rotation guide slot 26 of the outer pipe 20, so that movement of the rotation guide protrusion 39 is guided by the rotation guide slot 26.

[38] Furthermore, the rotating pipe 50 is inserted into the upper end of the outer pipe 20.

The rotating pipe 50 includes a rectangular body 51 which is inserted into the rectangular hole 38 that is formed through the inner pipe 30 inserted into the outer pipe 20, and a head part 52 which is provided on an upper end of the rectangular body 51 and is seated onto a stepped seat 22b formed in the head part 22 of the outer pipe 20. A slot 53, having the same width as that of the slot of the inner pipe 30, is formed in the rotating pipe 50 throughout the entire length of both the rectangular body 51 and the head part 52 in the same direction as the inner pipe 30. A locking protrusion 54 is provided on the rectangular body 51 at a position opposite the slot 53, so that the locking protrusion 54 is locked to the locking hole 37 of the inner pipe 30.

[39] It is preferable that a neck part of the rotating pipe 50 which couples the head part

52 to the rectangular body 51 have a circular shape such that the rotating pipe is rotated in a circular rotation support hole 22a formed at a central position in the head part 22 of the outer pipe 20.

[40] Furthermore, a fishline guide groove 55 is formed in an upper surface of the head part 52 of the rotating pipe 50 and is oriented in the same direction as the slot 53, so that the fishline guide groove 55 guides insertion of a fishline and prevents slippage between the head part 52 and the fingers of a user when the user rotates the head part 52 using his/her hands. Slip prevention grooves, which are oriented in a direction crossing to the fishline guide groove 55, may be formed in the upper surface of the head part 52 of the rotating pipe 50.

[41] Meanwhile, two separate cushion pads 14, each of which has a mountain-shaped uneven part 15, are inserted into the slot 12 formed in the bobber body 10. The mountain- shaped uneven parts 15 of the cushion pads 14 are in contact with the outer surface of the insertion pipe part 21 of the inner pipe 30. [42] The above-mentioned elements, other than the cushion pads 14, are assembled together by a fitting method without using adhesive. The outer surface of the bobber body 10 is coated with paint and fluorescent paint by the well-known method.

[43] As shown in FIG. 10, the general construction of a second embodiment of the present invention, except for a neck part 16, which is provided on a circumferential outer surface of an upper end of a bobber body 10 so that a ring-shaped chemical light 17 is fitted over the neck part 16, remains the same as the first embodiment, therefore further explanation is deemed unnecessary.

[44] As shown in FIG. 11, the general construction of a third embodiment of the present invention, except for a head part 22 of an outer pipe 20, which has a concave seat 24 on a circumferential outer surface thereof so that a ring-shaped chemical light 17 is fitted over the concave seat 24 of the head part 22, remains the same as the first embodiment, therefore further explanation is deemed unnecessary.

[45] The operation of the present invention having the above-mentioned construction will be described herein below with reference to FIGS. 1 through 11.

[46] When it is desired to insert a fishline into the holed bobber of the present invention, the slot 12 formed in the bobber body 10, the slot 23 of the outer pipe 20 inserted into the guide hole 11 of the bobber body 10, the slot 33 of the inner pipe 30, and the slot 43 of the lower sinker 40 are aligned with each other. Then, the slots 12, 23, 43 and 53 are opened, so that the fishline is allowed to be inserted through the slots.

[47] As such, to align the slots 12, 23, 43 and 53 with each other, the user holds the bobber body 10 with one hand and rotates the head part 32 of the inner pipe 30 and the head part 52 of the rotating pipe 50 using the thumb and the index finger of the other hand. Then, the rotating pipe 50 is rotated along with the inner pipe 30 in the outer pipe 20, because, as shown in FIGS. 6 and 7, the rectangular body 51 of the rotating pipe 50 is placed in the rectangular hole 38 of the inner pipe 30 and the locking protrusion 54 of the rotating pipe 50 is locked to the locking hole 37 of the inner pipe 30.

[48] Furthermore, because the fishline guide groove 55 and the slot 53 are formed in the upper surface of the head part 52 of the rotating pipe 50, when the user holds and rotates the head part 32 of the inner pipe 30 and the head part 52 of the rotating pipe 50 using the thumb or the index finger, the fishline guide groove 55 and the slot 53 are brought into contact with the finger. Thus, slippage is prevented from occurring at the junction between the head parts and the finger, so that the user can easily rotate the rotating pipe 50 and the inner pipe 30 without slippage.

[49] At this time, the outer pipe 20 is in the state of being locked into the bobber body 10 such that the outer pipe 20 is not rotated, and the lower sinker 40 is also in the state of being locked into the lower end of the outer pipe 20 such that the lower sinker 40 is not rotated.

[50] In detail, as shown in FIGS. 5 and 6, because the insertion protrusions 25 provided at diametrically opposite positions on the outer surface of the outer pipe 20 are inserted in the locking grooves 13 formed at diametrically opposite positions in the inner surface of the guide hole 11 of the bobber body 10, the outer pipe 20 cannot rotate in the bobber body 10. In addition, because the lower end of the outer pipe 20 which cannot rotate is inserted in the locking notches 41 of the lower sinker 40, the lower sinker 40 cannot rotate.

[51] Furthermore, as shown in FIGS. 4 and 8, because the elastic protrusion 36 provided on the outer surface of the inner pipe 30 is selectively inserted into the locking hole 27 or the release hole 28 of the outer pipe 20, the inner pipe 30 is prevented from idling in the outer pipe 20.

[52] In the case that the elastic protrusion 36 is inserted into the release hole 28, the slot

33 of the inner pipe 30 is aligned with the slot 23 of the outer pipe 20, so that the fishline is allowed to be inserted into or removed from the holed bobber. Furthermore, in this case, the inner pipe 30 is prevented from idling, and the slots 23 and 33 maintain alignment thereof. Meanwhile, in the case that the elastic protrusion 36 is inserted into the locking hole 27, the inner pipe 30 is rotated by an angle at which the locking hole 27 is spaced apart from the release hole 28, so that the slot 33 of the inner pipe 30 is misaligned from the slot 23 of the outer pipe 20. Then, the holed bobber enters a state in which the fishline cannot be inserted into or removed from the holed bobber. Of course, in this state, because the elastic protrusion 36 is inserted in the locking hole 27, the inner pipe 30 maintains its position without rotating.

[53] It has been explained that the inner pipe 30 is not rotated because of the elastic protrusion 36 inserted into the locking hole 27 or the release hole 28, but if the user holds and forcibly rotates the head part 32 of the inner pipe 30 and the head part 52 of the rotating pipe 50, the elastic protrusion 36, which has been seated into the locking hole 27 or the release hole 28, can be removed therefrom by the rotating force of the user, so that the head parts 32 and 52 can be rotated in a direction in which the user rotates them. Here, because the elastic protrusion 36 is provided on the elastic part 35, which is defined by the slits 34 formed in the insertion pipe part 31, the removal of the elastic protrusion 36, which has been seated into the locking hole 27 or the release hole 28, can be performed.

[54] Furthermore, as shown in FIGS. 1 and 9, the rotation guide protrusion 39 of the inner pipe 30 is inserted in the rotation guide slot 26 which is vertically formed in the outer pipe 20 to guide rotation of the inner pipe 30. Therefore, the inner pipe 30 can be rotated within an angular range, corresponding to the distance between the locking hole 27 and the release hole 28, that is, corresponding to the length of the rotation guide slot 26 which is equal to distance between the locking hole 27 and the release hole 28.

[55] While the inner pipe 30 is rotated within the above-mentioned angular range, when the slot 33 of the inner pipe 30 is aligned with the slot 23 of the outer pipe 20, as shown in FIG. 9(A), the fishline is allowed to be inserted into the holed bobber through the slots. As shown in FIG. 9(B), when the slot 33 of the inner pipe 30 is misaligned from the slot 23 of the outer pipe 20, the fishline cannot be inserted into the holed bobber. In addition, if a fishline has been inserted in the inner pipe 30, the fishline cannot exit the holed bobber.

[56] To fit a fishline, to which tackle is coupled, into the holed bobber, that is, to insert the fishline into the holed bobber after the slot 33 of the inner pipe 30 is aligned with the slot 23 of the outer pipe 20, as shown in FIG. 4, the user places the fishline 60 on the outer surface of the bobber body 10 at a position opposite the slot 12 and holds the fishline 60 along with the bobber body 10 using his/her hand. Thereafter, the user raises the fishline 60 above the bobber body 10 and inserts it into the fishline guide groove 55 formed in the head part 52 of the rotating pipe 50.

[57] Subsequently, the user inserts the fishline 60 into the slot 53 which is formed opposite the fishline guide groove 55, and pulls it downwards. Then, the fishline 60 enters the inner pipe 30 via a gap between two cushion pads 14 disposed in the slot 12 of the bobber body 10, the slot of the outer pipe 20, and the slot of the inner pipe 30.

[58] Here, the two cushion pads 14 are placed in the slot 12 of the guide hole 11 and are in contact with each other, and the fishline is inserted through a gap defined between the two cushion pads 14. Because each cushion pad 14 is made of compressed sponge such as EVA, the cushion pads can be contracted to allow the fishline to pass therethrough. In normal conditions, the cushion pads 14 are charged in the slot 12 in a state of being compressed, thus preventing water from entering the bobber body 10 through the slot 12. Furthermore, the cushion pads 14 make it possible for water currents to smoothly flow past the bobber body 10, thus preventing the bobber body 10 from undesirably rotating, thereby preventing the fishline from becoming tangled.

[59] Furthermore, as shown in FIGS. 1 and 4, when the elastic fishline, having entered the bobber body, is biased towards the slots, a contact area of the inner pipe 30 is reduced so that the mountain- shaped uneven parts 15 of the cushion pads 14 push the fishline towards the rectangular hole 38 of the inner pipe 30, thus preventing the fishline from being biased towards the slot 12. Therefore, when the inner pipe 30 is rotated, the fishline does not interfere with rotation of the inner pipe 30 and stably remains in the inner pipe 30 such that it can pass through the inner pipe 30 without restriction. In addition, because the head part 52 of the rotating pipe 50, which is seated in the stepped seat 22 formed in the head part 22 of the outer pipe 20, is surrounded by the head part 22 of the outer pipe 20, the fishline is prevented from being undesirably held between the head part 52 of the rotating pipe 50 and the head part 22 of the outer pipe 20 during casting, thus ensuring efficient fishing.

[60] In both the second embodiment shown in FIG. 10 and the third embodiment shown in FIG. 11, because the general construction thereof is the same as that of the first embodiment, the operation and effect thereof is also the same as those of the first embodiment. However, unlike the first embodiment, the second embodiment has the ring-shaped chemical light 17 which is fitted over the neck part 16 of the bobber body 10, and the third embodiment has the ring-shaped chemical light 17 which is fitted over the concave seat 24 formed around the head part 22 of the bobber body 10. Therefore, in these cases, when fishing at night, in whichever position the holed bobber is placed, the ring-shaped chemical light 17 is horizontally oriented and lights up the surface of the water. Thereby, the user can easily observe movement of the holed bobber to see if fish are taking the bait. Furthermore, during casting, the fishline, which is flying away along with the holed bobber, is prevented from becoming entangled with the ring-shaped chemical light 17, thus ensuring efficient fishing.
