[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-37949 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, when fixing the injection unit and the imaging unit with the jig, the injection unit and the imaging unit must be inserted through a through-hole in the jig, which takes time. Furthermore, if the tip of the injection unit is molded into a flat shape or the connection part of the injection unit is reinforced and becomes larger than the through-hole, the attachment and detachment process becomes difficult. Therefore, a structure that can simplify the process of holding the injection unit and the imaging unit has been desired.

[0015] According to the third invention, the retaining member is constructed by connecting the circumferential end of the first arc-shaped member and the circumferential end of the second arc-shaped member to each other, which makes it possible to mold the retaining member as a single unit, thereby reducing the manufacturing cost of the retaining member.

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that in the following embodiments, the drawings are appropriately simplified or modified, and the dimensional ratios and shapes of the various parts are not necessarily drawn accurately. [Example]

[0022] 1 is an overall view of an injection device 10 to which the present invention is applied. The injection device 10 includes an injection mechanism 12 and an imaging device 14.

[0023] The injection mechanism 12 includes an injector 16, a flexible pipe 18 connected at one end to the injector 16, and a tubular injection pipe 22 connected to the other end of the flexible pipe 18 via a connection reinforcement portion 20.

[0024] The injector 16 comprises a cylindrical container 24, a cylinder portion 26 from which the grease filled in the container 24 is injected, an extrusion portion 28 for moving a piston (not shown) built into the cylinder portion 26, and a spring 30 for biasing the extrusion portion 28 to a non-grease injection position.

[0025] When the operator presses the extrusion portion 28, the piston in the cylinder portion 26 is pushed out against the biasing force of the spring 30, and grease is injected from the cylinder portion 26 toward the flexible pipe 18. When the grease is injected toward the flexible pipe 18, the grease filled in the flexible pipe 18 and the injection pipe 22 moves toward the tip 22a of the injection pipe 22, and the grease is injected from the tip 22a of the injection pipe 22. In addition, the tip 22a of the injection pipe 22 is formed with a fluid injection port 31 having a rectangular cross section.

[0026] The imaging device 14 includes a monitor 32 and a scope 34 connected to the monitor 32. An image captured by a tip 35 of the scope 34 is displayed on a display unit 32a of the monitor 32. The imaging device 14 is used to check the amount of grease remaining in the area where grease is to be supplied and to confirm whether grease has been supplied to the appropriate area. As shown in FIG. 1, the tip 22a of the injection pipe 22 protrudes further from a holding member 36 (described later) toward the tip side than the tip 35 of the scope 34. Therefore, the scope 34 captures an image including the tip 22a of the injection pipe 22 and its surroundings.

[0027] Next, a description will be given of the holding member 36 that holds the injection pipe 22 and the scope 34 in a parallel arrangement. Fig. 2 is an enlarged view of the vicinity of the tip 22a of the injection pipe 22 and the tip 35 of the scope 34 in Fig. 1.

[0028] 2, the injection pipe 22 and the scope 34 are held in a state in which they are arranged in parallel by a holding member 36. The holding member 36 is made of an elastic material such as resin or spring steel.

[0029] Figure 3 is an external view of the holding member 36. The upper part of Figure 3 corresponds to the state in Figure 2, and the lower part of Figure 3 corresponds to a view of the holding member 36 in Figure 2 as seen from the direction of arrow A. The lower part of Figure 3 also corresponds to a cross-sectional view of the holding member 36 in Figure 2 cut along a plane perpendicular to the longitudinal direction (linear direction) of the injection pipe 22 and the scope 34. The longitudinal direction (linear direction) of the injection pipe 22 and the scope 34 corresponds to the direction in which the injection pipe 22 and the scope 34 extend.

[0030] As shown in FIG. 3 , the holding member 36 is composed of a first U-shaped member 36a and a second U-shaped member 36b, each of which has a U-shaped cross section. The pair of first U-shaped member 36a and second U-shaped member 36b are recessed in a direction in which the opening narrows near the opening. The holding member 36 is configured such that the opening of the first U-shaped member 36a and the opening of the second U-shaped member 36b are aligned in parallel, facing the same direction, and the contact portions of adjacent first U-shaped members 36a and 36b are connected. Furthermore, when the holding member 36 is in a state in which the injection pipe 22 and the scope 34 are held, the holding member 36 has a predetermined width W in the longitudinal direction of the injection pipe 22 and the scope 34. The first U-shaped member 36a and the second U-shaped member 36b correspond to the pair of members having a U-shaped cross section of the present invention.

[0031] When attaching the holding member 36 to the injection pipe 22 and the scope 34, the injection pipe 22 is inserted from the side with respect to the longitudinal direction (linear direction) of the injection pipe 22 so as to pass through the opening of the first U-shaped member 36a of the holding member 36. Similarly, the scope 34 is inserted from the side with respect to the longitudinal direction (linear direction) of the scope 34 so as to pass through the opening of the second U-shaped member 36b of the holding member 36.

[0032] Returning to FIG. 2 , a first elastic member 38 is interposed between the injection pipe 22 and the holding member 36. The first elastic member 38 is made of an elastic tape 39, and is attached to the injection pipe 22 by wrapping the tape 39 around the outer circumferential surface of the injection pipe 22. As a result, the portion of the injection pipe 22 to which the first elastic member 38 is attached is larger in the radial direction of the injection pipe 22 than the portion of the injection pipe 22 to which the first elastic member 38 is not attached. More specifically, the tape 39 constituting the first elastic member 38 is wrapped around the injection pipe 22 until the outer diameter D1 of the injection pipe 22 at the portion to which the first elastic member 38 is attached becomes larger than the inner diameter d1 of the first U-shaped member 36a. For example, the number of wraps of the tape 39 around the injection pipe 22 is adjusted so that a predetermined amount of interference is formed between the first elastic member 38 and the first U-shaped member 36a.

[0033] The position where the first elastic member 38 is attached is set at a position of length L1 based on the tip (fluid injection port 31) of the tip portion 22a of the injection pipe 22. The length L1 is determined in advance experimentally or through design. The first U-shaped member 36a of the holding member 36 is attached to the injection pipe 22 using the position of the first elastic member 38 as a marker. For example, as shown in FIG. 2, the first U-shaped member 36a is attached at a position where a boundary line 42 between the tape 39 wrapped around the injection pipe 22 and the injection pipe 22 is aligned with an end face 44 of the first U-shaped member 36a. In this way, the first elastic member 38 can be used to position the first U-shaped member 36a.

[0034] Furthermore, a second elastic member 40 is interposed between the scope 34 and the holding member 36. The second elastic member 40 is made of elastic tape 41, and is attached to the scope 34 by wrapping the tape 41 around the outer circumferential surface of the scope 34. As a result, the portion of the scope 34 to which the second elastic member 40 is attached is larger in the radial direction of the scope 34 than the portion of the scope 34 to which the second elastic member 40 is not attached. In detail, the tape 41 constituting the second elastic member 40 is wrapped around the scope 34 until the outer diameter D2 of the scope 34 at the portion to which the second elastic member 40 is attached becomes larger than the inner diameter d2 of the second U-shaped member 36b. For example, the number of wraps of the tape 41 around the scope 34 is adjusted so that a predetermined amount of interference is formed between the second elastic member 40 and the second U-shaped member 36b.

[0035] The position at which the second elastic member 40 is attached is set to a position of length L2 based on the tip of the distal end portion 35 of the scope 34. Length L2 is determined in advance experimentally or through design. The second U-shaped member 36b of the holding member 36 is attached to the scope 34 using the position of the second elastic member 40 as a marker. For example, as shown in FIG. 2, the second U-shaped member 36b is attached at a position where the boundary line 46 between the tape 41 wrapped around the scope 34 and the scope 34 and the end face 48 of the second U-shaped member 36b are aligned in a straight line. In this way, the second elastic member 40 can be used to position the second U-shaped member 36b.

[0036] Next, one mode of use of the injection device 10 configured as described above will be described. FIG. 4 is a view from the inside of the case 50 showing the state in which the injection pipe 22 and scope 34 are inserted into the case 50 to supply grease to parts of the case 50 that require grease. FIG. 5 is a view of FIG. 4 seen from the outside of the case 50. The modes shown in FIGS. 4 and 5 show a mode in which grease is injected between a release bearing 52 of a dry clutch that connects and disconnects a manual transmission and a power source and a release fork 54 that contacts the release bearing 52. Note that a contact portion 60 between the release bearing 52 and the release fork 54 corresponds to the corresponding portion within the clamping space of the present invention.

[0037] In Figure 4, the release bearing 52 is attached so as to be movable relative to the rotary shaft 56 in the axial direction. The release fork 54 is a longitudinally shaped member that is rotatable around a support part (not shown) as a fulcrum. An end 54a of the release fork 54 on the longitudinal side that is housed inside the case 50 is bifurcated so as to sandwich the rotary shaft 56. In the assembled state, the end 54a of the release fork 54 housed inside the case 50 comes into contact with the release bearing 52. Note that Figure 4 shows a state in which the end 54a of the release fork 54 is separated from the release fork 54 when grease is supplied.

[0038] Grease is applied to a contact portion 60 between the release bearing 52 and the end portion 54a of the release fork 54, as they come into sliding contact with each other. However, when driving on a flooded road, water or foreign matter may enter the case 50, causing the grease at the contact portion 60 to flow out. When this happens, there is a risk of poor sliding between the release bearing 52 and the release fork 54. Therefore, if the grease at the contact portion 60 flows out, grease is supplied to the contact portion 60 between the release bearing 52 and the release fork 54 using the injection device 10.

[0039] As shown in FIGS. 4 and 5 , a through-hole 58 is formed in the case 50 for inserting the release fork 54 into the case 50, and the release fork 54 passes through the through-hole 58. Furthermore, an operator holds the injection pipe 22 and the scope 34 and inserts them into the case 50 through a gap between the through-hole 58 and the release fork 54. Peripheral components (not shown in FIG. 4 ) are housed within the case 50. In reality, the injection pipe 22 and the scope 34 reach the contact portion 60 by passing through a space within the case 50 so as not to interfere with the peripheral components. As shown in FIG. 4 , the holding member 36 is also inserted into the case 50. The portions of the injection pipe 22 and the scope 34 that are inserted into the case 50 correspond to the insertion portion of the present invention. The portion of the injection pipe 22 that is inserted into the case 50 corresponds to the injection portion of the present invention. The portion of the scope 34 that is inserted into the case 50 corresponds to the imaging portion of the present invention.

[0040] As shown in Figure 4, when the tip 22a of the injection pipe 22 reaches the contact point 60 between the release bearing 52 and the release fork 54, the operator activates the injector 16 to inject grease from the fluid injection port 31 of the tip 22a, thereby supplying the grease to the contact point 60.

[0041] To improve workability, the insertion depth of the injection pipe 22 and the scope 34 into the case 50 that enables grease to be supplied to the contact portion 60 is determined in advance through experimentation or design. For example, the insertion depth is determined in advance with the tip 22a of the injection pipe 22 as the reference (zero), and the injection pipe 22 and the scope 34 are inserted into the case 50 by that insertion depth to enable grease to be supplied to the contact portion 60. Alternatively, the insertion depth is determined in advance with the holding member 36 as the reference (zero), and the injection pipe 22 and the scope 34 are inserted into the case 50 by that insertion depth to enable grease to be supplied to the contact portion 60. Note that for fine adjustments, the position is adjusted by an operator while referring to an image captured by the scope 34 and displayed on the display unit 32a of the monitor 32. At this time, because the injection pipe 22 is inserted into the first U-shaped member 36a, interference with the scope 34 is prevented when fine-tuning the position of the injection pipe 22. Similarly, since the scope 34 is inserted into the second U-shaped member 36b, interference with the injection pipe 22 is prevented when fine-tuning the position of the scope 34.

[0042] Furthermore, during the transitional period in which the injection pipe 22 and the scope 34 are being inserted into the case 50, a position (angle θ) of the scope 34 relative to the injection pipe 22 that avoids interference with peripheral components within the case 50 is determined in advance through experiments or design. For example, as shown in FIG. 5 , the angle θ about the injection pipe 22 is determined in advance, with the state in which the injection pipe 22 and the scope 34 are horizontally positioned as a reference (zero). When the injection pipe 22 and the scope 34 are inserted into the case 50 through the through-hole 58 of the case 50, the scope 34 is inserted into the case 50 with the orientation rotated by the angle θ in advance. As a result, the injection pipe 22 and the scope 34 can be positioned appropriately without interfering with peripheral components within the case 50. Note that, while it is preferable for the injection pipe 22 and the scope 34 to be horizontal from the standpoint of ease of viewing the scope 34, the scope 34 is rotated appropriately about the injection pipe 22 to avoid interference with peripheral components.

[0043] As described above, the injection pipe 22 and the scope 34 are held by the holding member 36. The holding member 36 is attached by being inserted laterally in the longitudinal direction (linear direction) of the injection pipe 22 and the scope 34. Specifically, the holding member 36 is attached by passing the injection pipe 22 through the opening of the first U-shaped member 36a of the holding member 36 and passing the scope 34 through the opening of the second U-shaped member 36b. This improves the ease of attaching the holding member 36 to the injection pipe 22 and the scope 34.

[0044] On the other hand, in the conventional structure, the injection pipe 22 and the scope 34 were held by being inserted into a member (holding member) having two through holes, which required a lot of work. Furthermore, if the tip portion 22a of the injection pipe 22 and the connection reinforcement portion 20 were made larger as in this embodiment, it would be difficult to insert the injection pipe 22 into the through holes in the conventional structure, making it difficult to attach and detach the injection pipe 22. As a result, it would also be difficult to use the injection pipe 22 for other purposes. In contrast, the holding member 36 can be easily attached and detached regardless of the dimensions of the tip portion 22a and the connection reinforcement portion 20, which is easy to use and makes it easy to use the injection pipe 22 and the scope 34 for other purposes (improved versatility).

[0045] Furthermore, since the first elastic member 38 is interposed between the injection pipe 22 and the first U-shaped member 36a of the holding member 36, even if a gap occurs between the injection pipe 22 and the first U-shaped member 36a, the gap is filled by the first elastic member 38. At this time, by appropriately setting the compression amount of the first elastic member 38, the resistance acting between the first elastic member 38 and the first U-shaped member 36a becomes appropriate, and the holding force of the holding member 36 becomes appropriate. Furthermore, since the first elastic member 38 is interposed, injection pipes 22 with different diameters can be used, improving versatility.

[0046] Furthermore, because the second elastic member 40 is interposed between the scope 34 and the second U-shaped member 36b of the holding member 36, even if a gap occurs between the scope 34 and the second U-shaped member 36b, the gap is filled by the second elastic member 40. At this time, by appropriately setting the compression amount of the second elastic member 40, the resistance acting between the second elastic member 40 and the second U-shaped member 36b becomes appropriate, and the holding force by the holding member 36 becomes appropriate. Furthermore, because the second elastic member 40 is interposed, scopes 34 of different diameters can be used, improving versatility.

[0047] As described above, according to this embodiment, the holding member 36 can be inserted laterally in the longitudinal direction of the injection pipe 22 and the scope 34, thereby easily holding the injection pipe 22 and the scope 34 side by side. Furthermore, because the first elastic member 38 is interposed between the injection pipe 22 and the holding member 36, the injection pipe 22 can be appropriately held by the elastic force of the first elastic member 38 even if the diameter of the injection pipe 22 varies. Furthermore, because the second elastic member 40 is interposed between the scope 34 and the holding member 36, the scope 34 can be appropriately held by the elastic force of the second elastic member 40 even if the diameter of the scope 34 varies.

[0048] Furthermore, according to this embodiment, the holding member 36 is a member in which the first U-shaped member 36a and the second U-shaped member 36b, each having a U-shaped cross section, are connected in a state of being adjacent to each other in parallel. Therefore, when attaching the holding member 36, the injection pipe 22 and the scope 34 can be attached separately. In relation to this, when attaching the holding member 36 to one of the injection pipe 22 and the scope 34, the other does not interfere, improving workability. Furthermore, because the first elastic member 38 is attached to the injection pipe 22, the attachment work of the first elastic member 38 is facilitated. Furthermore, because the second elastic member 40 is attached to the scope 34, the attachment work of the second elastic member 40 is facilitated.

[0049] Furthermore, according to this embodiment, the first elastic member 38 is formed by wrapping elastic tape 39 around the outer circumferential surface of the injection pipe 22, so that the first elastic member 38 can be easily attached to the injection pipe 22. Furthermore, the size of the first elastic member 38 can be easily adjusted by changing the number of turns of the tape 39. Furthermore, a boundary line 42 between the first elastic member 38 and the injection pipe 22, which is formed by the tape 39 wrapped around the injection pipe 22, can be used to position the holding member 36. Furthermore, the second elastic member 40 is formed by wrapping elastic tape 41 around the outer circumferential surface of the scope 34, so that the second elastic member 40 can be easily attached to the scope 34. Furthermore, the size of the second elastic member 40 can be easily adjusted by changing the number of turns of the tape 41. Furthermore, a boundary line 46 between the second elastic member 40 and the scope 34, which is formed by the tape 41 wrapped around the scope 34, can be used to position the holding member 36.

[0050] Next, another embodiment of the present invention will be described. In the following description, parts common to the above embodiment will be designated by the same reference numerals and description thereof will be omitted. [Example]

[0051] Fig. 6 is a diagram showing the shape of a holding member 80 corresponding to another embodiment of the present invention, and shows a state in which the injection pipe 22 and the scope 34 are held in a parallel arrangement by the holding member 80. Fig. 6 also corresponds to a cross-sectional view taken along a plane perpendicular to the longitudinal direction (linear direction) of the injection pipe 22 and the scope 34 in the attached state of the injection pipe 22 and the scope 34.

[0052] The holding member 80 has a cross section formed in a substantially ω shape. The holding member 80 is composed of a first arc-shaped member 80a and a second arc-shaped member 80b, each of which has an arc-shaped cross section. The arc lengths of the first arc-shaped member 80a and the second arc-shaped member 80b are at least longer than a semicircle. With the first arc-shaped member 80a and the second arc-shaped member 80b arranged in parallel, one circumferential end of the first arc-shaped member 80a and one circumferential end of the second arc-shaped member 80b are connected to each other. The other circumferential end of the first arc-shaped member 80a and the other circumferential end of the second arc-shaped member 80b face each other, and an opening 82 is formed between these opposing ends.

[0053] As shown in Figure 6, the injection pipe 22 is inserted into the inner periphery of the first arc-shaped member 80a. A first elastic member 38 is inserted in a compressed state between the injection pipe 22 and the first arc-shaped member 80a. The scope 34 is inserted into the inner periphery of the second arc-shaped member 80b. A second elastic member 40 is inserted in a compressed state between the scope 34 and the second arc-shaped member 80b. The injection pipe 22 and the scope 34 are held by the holding member 80 as the first elastic member 38 and the second elastic member 40 are compressed.

[0054] When attaching the holding member 80 to the injection pipe 22 and the scope 34, the holding member 80 is inserted from the side relative to the longitudinal direction (linear direction) of the injection pipe 22 and the scope 34 with the opening 82 of the holding member 80 facing the injection pipe 22 and the scope 34. In this way, the holding member 80 can be easily attached to the injection pipe 22 and the scope 34. Furthermore, because the holding member 80 can be molded as a single unit, the manufacturing cost is reduced compared to the holding member 36 of the first embodiment described above. The above-described holding member 80 also provides substantially the same effects as those of the first embodiment described above. [Example]

[0055] Fig. 7 is a diagram showing the shape of a holding member 90 according to yet another embodiment of the present invention, and shows a state in which the injection pipe 22 and the scope 34 are held in a parallel arrangement by the holding member 90. Fig. 7 also corresponds to a cross-sectional view taken along a plane perpendicular to the longitudinal direction (linear direction) of the injection pipe 22 and the scope 34 in the attached state of the injection pipe 22 and the scope 34.

[0056] The holding member 90 is formed in an annular shape with an O-shaped cross section. A notch 92 is formed in part of the circumferential direction of the holding member 90. As shown in FIG. 7 , the injection pipe 22 and the scope 34 are held in parallel on the inner circumferential side of the holding member 90. A first elastic member 38 is interposed in a compressed state between the injection pipe 22 and the holding member 90. A second elastic member 40 is interposed in a compressed state between the scope 34 and the holding member 90. The injection pipe 22 and the scope 34 are held by the holding member 90 as the first elastic member 38 and the second elastic member 40 are compressed.

[0057] When attaching the holding member 90 to the injection pipe 22 and the scope 34, the injection pipe 22 and the scope 34 are inserted from the side of the injection pipe 22 and the scope 34 in the longitudinal direction (linear direction) so that they pass through the notch 92 of the holding member 90. In this way, the holding member 90 can be easily attached to the injection pipe 22 and the scope 34. Furthermore, because the holding member 90 can be molded as a single unit, the manufacturing cost is reduced compared to the holding member 36 of the first embodiment described above. The above-described holding member 90 also provides substantially the same effects as the first embodiment described above. [Example]

[0058] 8 is a diagram showing the shape of a retaining member 100 corresponding to yet another embodiment of the present invention. When comparing the retaining member 100 with the retaining member 36 of the first embodiment, the basic shape is the same, but the difference is that a first elastic member 102 and a second elastic member 104 are attached to the retaining member 100.

[0059] The holding member 100 is composed of a first U-shaped member 100a and a second U-shaped member 100b, each of which is formed in a U-shape. The first U-shaped member 100a and the second U-shaped member 100b are both recessed in the vicinity of their openings in a direction that narrows the openings.

[0060] Furthermore, a first elastic member 102 made of rubber or the like is attached to the inner circumferential surface of the first U-shaped member 100a by adhesive or the like. The first elastic member 102 is formed in an arc shape along the inner circumferential surface of the first U-shaped member 100a. A second elastic member 104 made of rubber or the like is attached to the inner circumferential surface of the second U-shaped member 100b by adhesive or the like. The second elastic member 104 is formed in an arc shape along the inner circumferential surface of the second U-shaped member 100b. In this way, even when the first elastic member 102 and the second elastic member 104 are provided on the holding member 100, the same effects as those of the above-described embodiment can be obtained. Furthermore, when the first elastic member 102 and the second elastic member 104 are provided on the holding member 100, the first elastic member 102 and the second elastic member 104 are not provided on the injection pipe 22 and the scope 34, making it easier to use the injection pipe 22 and the scope 34 for other purposes, improving versatility.

[0061] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the present invention can also be applied to other embodiments.

[0062] For example, in the above-described embodiment, the injection device 10 is used to supply grease to the contact portion 60 between the release bearing 52 and release fork 54 that constitute a dry clutch of a manual transmission. However, the present invention is not limited to this embodiment. For example, the present invention can also be applied to a predetermined greasing portion of a parking brake, a greasing portion of a wheel brake, a greasing portion inside a pulley, a greasing portion of a rotating portion, or a greasing portion of a sliding portion. In short, the present invention can be applied as appropriate to any portion that requires the supply of grease within a pinched space. Furthermore, the present invention is not limited to vehicles, and can be applied as appropriate to any industrial machine that has a portion that requires the supply of grease.

[0063] Furthermore, in the above-described embodiment, the first elastic member 38 is interposed between the injection pipe 22 and the first U-shaped member 36a, and the second elastic member 40 is interposed between the scope 34 and the second U-shaped member 36b. However, it is also possible to use only one of the first elastic member 38 and the second elastic member 40. That is, it is also possible to interpose the first elastic member 38 between the injection pipe 22 and the first U-shaped member 36a, while the scope 34 and the second U-shaped member 36b are in direct contact with each other. Alternatively, it is also possible to interpose the second elastic member 40 between the scope 34 and the second U-shaped member 36b, while the injection pipe 22 and the first U-shaped member 36a are in direct contact with each other.

[0064] Furthermore, in the above-described embodiment, the first elastic member 38 is configured from an elastic tape wound around the outer circumferential surface of the injection pipe 22, but the first elastic member 38 is not necessarily limited to this. For example, any elastic member such as rubber may be attached to the outer circumferential surface of the injection pipe 22, as long as it is capable of filling the gap between the injection pipe 22 and the holding member 36 and generating a holding force by elastically deforming when the holding member 36 is attached.

[0065] Furthermore, in the above-described embodiment, the second elastic member 40 is made of elastic tape wrapped around the outer peripheral surface of the scope 34, but the second elastic member 40 is not necessarily limited to this. For example, any elastic member such as rubber may be attached to the outer peripheral surface of the scope 34, as long as it is capable of filling the gap between the injection pipe 22 and the holding member 36 and generating a holding force by elastically deforming when the holding member 36 is attached.

[0066] In the above-described fourth embodiment, the first elastic member 102 and the second elastic member 104 are attached to the holding member 100, but similarly, the first elastic member and the second elastic member may be attached to the holding member 80 in the second embodiment. Furthermore, similarly, the first elastic member and the second elastic member may be attached to the holding member 90 in the third embodiment.

[0067] Furthermore, in the fourth embodiment described above, the first elastic member 102 and the second elastic member 104 are attached to the holding member 100. However, it is also possible for only one of these members to be attached to the holding member 100. For example, the first elastic member 102 may be attached to the first U-shaped member 100a of the holding member 100, while the second elastic member 104 may be attached to the scope 34. Alternatively, the second elastic member 104 may be attached to the second U-shaped member 100b of the holding member 100, while the first elastic member 102 may be attached to the injection pipe 22. In this regard, it is also possible for the holding member 80 of the second embodiment to have either the first elastic member or the second elastic member attached to the holding member 80. Similarly, it is also possible for the holding member 90 of the third embodiment to have either the first elastic member or the second elastic member attached to the holding member 90.

[0068] In the above-described embodiment, the cross section of the tip 22a of the injection pipe 22 is rectangular, but the cross section of the tip 22a is not necessarily limited to a rectangular shape. For example, the cross section of the tip 22a of the injection pipe 22 may be cylindrical, like the other portions of the tip 22a.

[0069] It should be noted that the above is merely one embodiment, and the present invention can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. [Explanation of symbols]
