Description

  The present invention mainly relates to a car wash machine for cleaning dirt or the like adhering to a surface to be cleaned such as an outer surface of an automobile or a vehicle or a wheel.

  Various improvements have been made to the conventional wheel cleaning brush and the wheel cleaning brush. For example, in an automobile wheel cleaning device, the wheel cleaning brush includes a brush base supported by the brush support shaft and the brush. Japanese Patent No. 3696585 discloses a wheel washing brush composed of brush bristles in which long brush groups and shorter brush groups attached to a base are alternately attached in the direction of rotation of the brush base. .

Japanese Patent No. 3696585

  For example, a conventional cleaning brush such as a wheel discloses a technique having the above-described characteristics. However, in the technique disclosed in Japanese Patent No. 3696585, a long brush group and a short brush group rotate. Because the long brush group and the short brush group contact the wheel cap alternately in the rotation direction, the urging force applied to the wheel cap is not constant and the brush is knocked. However, after making the wheel cap jump, there was a problem that the wheel cap dropped off from the wheel. Further, in the manufacturing process of the brush, there is a step of trimming the tip of the brush in order to align the hair length of the brush. As described above, in the wheel cleaning device for an automobile, the wheel cleaning brush is supported by the brush support shaft. Since the brush base and the bristle attached to the brush base and the long brush group and the shorter brush group are alternately attached in the rotation direction of the brush base, The work of trimming the tip of the cleaning brush could not be performed, and the task of trimming the tip of each brush group was necessary. Therefore, there is a problem that the brush becomes expensive. Further, as described above, since the long brush group and the shorter brush group are composed of the brush hairs alternately attached in the rotation direction of the brush base, the mutual brush groups are formed with steps. . For this reason, there has been a problem that cleaning residue occurs.

The present invention was made in order to solve the above problems, and even if the hair and waist of a cleaning brush such as a wheel is set strongly, the wheel or the like to be cleaned is not damaged, It is an object of the present invention to provide a wheel cleaning brush that exhibits high cleaning performance and a car wash machine equipped with the wheel cleaning brush.

  In order to achieve the above-mentioned object, the present invention provides a first problem-solving means comprising: a wheel cleaning brush for cleaning dirt or the like adhering to a surface to be cleaned of an automobile wheel or tire; Has a pedestal and a brush part, and the brush part is flocked to the upper part of the pedestal with a plurality of brush pieces, and at least one of the brush pieces has a different hardness and has a molecule in the longitudinal direction. It is formed of at least two kinds of oriented multilayer coated wires, and at least a part of the outer peripheral surface of the wire is covered.

  Further, the second problem solving means has a configuration in which a reinforcing member having a mechanical strength larger than that of the brush piece is formed at least on the outer periphery of the brush portion in the cleaning brush such as a wheel of the first problem solving means. It is a thing.

  Further, according to a third problem solving means, in the cleaning brush such as a wheel of the first to second problem solving means, the reinforcing member is formed lower than the bristle length of the brush portion, and moreover than the brush piece. Also, the hair and waist are large.

  The fourth problem solving means includes a drive source, a nozzle for spraying a cleaning agent and water sprayed on the surface to be cleaned, and a drying means for drying the surface to be cleaned after cleaning. This is a car washer equipped with a cleaning brush such as a wheel described in the means for solving problems.

  The cleaning brush such as a wheel of the present invention has a pedestal and a brush part, and the brush part is planted on the upper part of the pedestal with a plurality of brush pieces, and at least one of the brush pieces has different hardness. It is formed of at least two or more types of multi-layer coated wires having molecular orientation in the longitudinal direction, and at least a part of the outer peripheral surface of the wire is coated. Since the rigidity can be increased and it is difficult for the hair to fall down, even when the bristle of the bristle material for the brush is set strongly, it can be brought into contact with the strong bristle on the wheel of the car body that is the surface to be cleaned, etc. It is extremely excellent in that it can remove scratches on the surface to be cleaned and exhibit high detergency without causing scratches on the wheel or the like.

  The first invention is a wheel cleaning brush for cleaning dirt or the like adhering to a surface to be cleaned of an automobile wheel or tire. The wheel cleaning brush has a pedestal and a brush portion, and the brush portion is A plurality of brush pieces are planted on top of the pedestal, and at least one of the brush pieces is formed of at least two or more types of multi-layer coated wires having different hardness and molecular orientation in the longitudinal direction. In addition, since at least a part of the outer peripheral surface of the wire is covered, the outer layer portion that comes into contact with the surface to be cleaned has a lower hardness than the core portion and a soft form is adopted. Since the brush piece comes into contact with the surface flexibly, there is no scratch such as a brush mark on the surface to be cleaned. In addition, the hair waist as a brush piece is held, and the hair waist is set strongly against the surface to be cleaned. For this reason, even if the bristle of the brush piece is set strongly, the car body that is the surface to be cleaned is not damaged, and the bristle of the brush piece can be set strongly by the core part harder than the outer layer part. Can exhibit high detergency.

  According to a second aspect of the present invention, there is provided a cleaning brush for wheels and the like having the structure according to claim 1, wherein a reinforcing member having a mechanical strength larger than that of the brush piece is formed at least on the outer periphery of the brush portion. On the other hand, when the brush piece comes into contact with the brush piece, even when bending stress that causes the hair fall of the brush piece or the hair follicle is constantly applied, the outer periphery of the brush portion has a mechanical strength larger than that of the brush piece. Since the reinforcing member is formed, the brush piece of the cleaning brush such as a wheel does not fall down or generate fuzz.

  According to a third aspect of the present invention, in the cleaning brush for wheels and the like having the configuration according to claim 2, the reinforcing member is formed lower than the bristle length of the brush part, and has a larger fluff than the brush piece. For this reason, the reinforcing member having a bristle waist larger than that of the brush piece is formed with a lower bristle length at the time of cleaning, so that the reinforcing member does not directly contact the surface to be cleaned. Therefore, scratches such as brush marks do not enter the surface to be cleaned. In addition, when the brush piece comes into contact with the surface to be cleaned, even when bending stress that causes the brush piece to fall down or cause hair flaws is constantly applied, The brush piece of the equal cleaning brush does not fall down or cause fuzz.

  A fourth invention includes a drive source, a nozzle for spraying cleaning agent and water sprayed on the surface to be cleaned, and a drying means for drying the surface to be cleaned after cleaning. Since it is a car wash machine equipped with a cleaning brush such as a wheel, the hair and waist can be brought into strong contact with the surface to be cleaned without causing scratches. For this reason, the car wash machine has a high cleaning performance such that the cleaning brush such as a wheel is set to high-speed rotation, and even if the cleaning time is set to a short time, the surface to be cleaned is not damaged and there is no cleaning residue. Is granted. Further, even when the rotation of the cleaning brush such as a wheel is suddenly changed from a low-speed rotation to a high-speed rotation, the same action as described above is given to the car wash machine. Therefore, it is possible to provide a car wash machine that can exhibit extremely high cleanability without damaging the vehicle body that is the surface to be cleaned.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Example 1)
Example 1 is shown in FIGS. FIG. 1 is a perspective view of a brush piece of a cleaning brush such as a wheel of the present invention as seen from the front side. In FIG. 1, 1 is a brush piece, 10 is a cleaning brush such as a wheel, 11 is a brush portion, 12 is a base, and 13 is a reinforcing member. FIG. 2 is a cross-sectional view of the brush piece of FIG. In FIG. 2, 1 is a brush piece, 10 is a cleaning brush such as a wheel, 11 is a brush portion, 12 is a pedestal, 13 is a reinforcing member, and 14 is a mounting hole. FIG. 3 is a perspective view of a brush piece of a cleaning brush such as a wheel of the present invention as seen from the front side. In FIG. 3, 1 is a brush piece, 2 is an outer layer part, 4 is a tip crack part, and 5 is a curved part. 4 is a cross-sectional view of the brush piece of FIG. In FIG. 4, 3 is a core part and 7 is a side edge part. FIG. 5 is a front view of a brush piece according to another embodiment of the brush piece of FIG. In FIG. 5, 6 is a slit.

  As shown in FIGS. 1 and 2, the cleaning brush 10 such as a wheel has a brush portion 11 formed in a direction orthogonal to the upper surface of a disk-shaped base 12. Further, the brush portion 11 presses the brush piece 1 against the flocked hole with a lead-in line of nylon or the like, folds the brush piece 1 and folds the lead-in line over the inner peripheral surface of the base 12, and the brush piece 1 is put on the base 12. Has been pulled in to be fixed. Further, a reinforcing member 13 is drawn into the pedestal 12 at an appropriate interval on the outer peripheral portion of the brush portion 11 and is implanted. The reinforcing member 13 is formed of, for example, a nylon resin having a hardness higher than that of the brush piece 1 of the brush portion 11 and having a low bristle length. Further, the cleaning brush 10 such as a wheel is attached to the drive shaft 21 of FIG. 6 through an attachment hole 14 formed in the base 12. Further, as shown in FIGS. 3 and 4, the brush piece 1 is formed in a long shape in which the core portion 3 is covered with the outer layer portion 2 and the entire outer peripheral surface of the core portion 3 is covered. The cross section is formed in a wave shape having a substantially round side end portion 7 and a curved portion 5. The brush piece 1 is made of foamed ethylene vinyl acetate for the outer layer portion 2 and low density polyethylene resin for the core portion 3. Moreover, the front crack part 4 is formed in the both ends of a longitudinal direction. Further, the brush piece 1 may be used by forming a slit 6 as shown in FIG. The brush piece 1 is a surface to be cleaned by forming the tip cracked portion 4 or the slit 6 so that the tip cracked portion 4 or the slit 6 comes into contact with the fine irregularities of the surface to be cleaned such as a wheel. The dirt adhering to the surface to be cleaned can be scraped and removed by the tip crack 4 or the slit 6 without damaging the vehicle body. Furthermore, the brush piece 1 can also employ a form in which the slit 6 is formed and the tip 4 is formed at the tip of the slit 6. When the said form is employ | adopted, the brush piece 1 can prevent or suppress that a to-be-cleaned surface is damaged since the fur waist becomes so soft that it approaches a front-end | tip part. Moreover, since the brush piece 1 has the curved part 5, water etc. can be temporarily stored in the curved part 5 at the time of a car wash, and the water retention at the time of a car wash can be improved. Furthermore, since the side end portion 7 of the cross section has a substantially round shape with no corners, it is possible to suppress the adhesion of scratches to the surface to be cleaned.

  The operation and action of the cleaning brush 10 such as a wheel of the present invention are as follows. The brush piece 1 forming the brush portion 11 removes dirt and the like adhering to the surface to be cleaned by rotating the cleaning brush 10 such as the wheel while contacting the surface to be cleaned such as the wheel while being urged. ing. At this time, the brush piece 1 is constantly subjected to bending stress that causes the fall of the hair and the hair fistula in the lateral direction. Since the cleaning brush 10 such as a wheel is provided with the brush piece 1, the bristle of the brush piece 1 is strongly set in the core portion 3 of the brush piece 1 that does not directly contact the surface to be cleaned, and is more flexible than the core portion 3. The outer layer portion 2 comes into contact with the surface to be cleaned. Therefore, the surface to be cleaned is not damaged, and high cleanability can be imparted to the surface to be cleaned with strong fur. Therefore, it is possible to provide a cleaning brush 10 such as a wheel that has no scratches on a surface to be cleaned such as a wheel that is a surface to be cleaned and has high cleaning properties.

  The cleaning brush 10 such as a wheel reinforces the bending stress generated when the brush piece 1 is urged against and contacted with the surface to be cleaned because the reinforcing member 13 is formed on the outer periphery of the brush piece 1. The member 13 can be strongly repelled. For example, in the case of a house structure, the reinforcing member 13 corresponds to a pillar in the house structure. As long as the brush piece 1 itself has a high mechanical strength, it is possible to prevent hair lashes and hair fall, but there is a problem of scratching the surface to be cleaned, and it is as flexible as possible. Some are desirable. However, the flexible member has a low mechanical strength, and there is a problem in that hair folds and hair fall easily occur. Therefore, the mechanical strength reinforcing member 13 larger than the brush piece 1 is used as a column to improve the mechanical strength of the cleaning brush 10 such as a wheel, and the brush piece 1 in contact with the surface to be cleaned is made a flexible member. In this way, it is possible to provide a cleaning brush 10 such as a wheel that prevents scratches on the surface to be cleaned and does not cause hair flaws or hair fall. The reinforcing member 13 may be in the form of a thin plate or a single row flocking brush. When the said form is employ | adopted, the said brush piece 1 can be reinforced without taking a space.

  As for the detailed shape and dimensions of the brush piece 1, the optimum shape and dimensions can be set by selecting the material of the outer layer portion 2 and the core portion 3, the shape of the curved portion 5, and the like. For example, an elastic body in which a covalent cross-linking structure is formed between molecules of a low-density polyethylene resin as a material of the core portion 3, and an elasticity in which a covalent cross-linking structure is formed between molecules of an ethylene vinyl acetate resin as a material of the outer layer portion 2. In the case of using the foam having, the length in the width direction of the brush piece 1 is 0.5 mm to 30 mm, and the thickness from the upper vertex of the curved portion 5 to the lower bottom point is 0.5 mm to 3 mm, more preferably The length in the width direction is preferably 1 mm to 15 mm, and the thickness from the upper vertex to the lower bottom point of the curved portion 5 is preferably 0.7 mm to 1.5 mm. If the length in the width direction or the thickness from the top vertex to the bottom bottom point of the curved portion 5 is less than 0.5 mm, the strength of the brush piece 1 required for removing dirt adhering to the surface to be cleaned can be obtained. In comparison, the strength may be reduced and the durability may be deteriorated. Further, if the length in the width direction is larger than 30 mm, the brush piece 1 does not come into contact with the details of the surface to be cleaned, and unwashed parts may be generated, resulting in poor cleaning performance. Further, if the thickness from the upper part of the curved portion 5 to the bottom bottom point is larger than 3 mm, the strength is higher than the strength of the brush piece 1 required for removing the dirt adhering to the surface to be cleaned. Therefore, the surface to be cleaned may be scratched.

  The outer layer part 2 foams the ethylene vinyl acetate resin, and at the time of foaming, a cross-linking agent is added to the foaming agent, and the foaming has elasticity in which a covalent cross-linking structure is formed between the molecules of the ethylene vinyl acetate resin. It is composed of bodies. As described above, an elastic foam having a covalently crosslinked structure formed between molecules of a resin such as ethylene vinyl acetate resin is generally called a crosslinked foam. The expansion ratio of the outer layer portion 2 is preferably 2 to 15 times and more preferably adjusted to 2.5 to 12 times for the purpose of not scratching the surface to be cleaned. If the expansion ratio is less than 2 times, it will be too hard and scratch the surface to be cleaned. If it is greater than 15 times, the frictional resistance will increase and the cleaning noise during cleaning will increase. The surface to be cleaned is easily damaged. In addition, as a material used for the outer layer part 2, in addition to the ethylene vinyl acetate resin, a polyolefin resin such as polyethylene resin, polypropylene resin, ethylene methyl acrylate resin, ethylene ethyl acrylate resin, ethylene butyl acrylate resin may be used. The materials as described above may be used alone or in combination.

  The foaming agent is not particularly limited as long as it has been conventionally used in the production of foams. For example, sodium bicarbonate, ammonium bicarbonate, azodicarbonamide, benzenesulfonyl hydrazide, dinitrosopenta Pyrolytic foaming agents such as methylenetetramine, toluenesulfonhydrazide, 4,4-oxybisbenzenesulfonylhydrazide are preferably used, and the above materials may be used alone or in combination.

  The cross-linking agent is not particularly limited as long as it has been used in the production for the purpose of imparting elasticity to the foam. For example, dicumyl peroxide, 2,5-dimethyl-2 Organic peroxides such as 1,5-bis-tertiarybutyl peroxyhexene and 1,3-bis-tertiary peroxyisopropylbenzene are preferably used, and the materials may be used alone or in combination. .

  The method of imparting elasticity to resins such as polyethylene resin, polypropylene resin, ethylene vinyl acetate resin, ethylene methyl acrylate resin, ethylene ethyl acrylate resin, ethylene butyl acrylate resin, etc. is not limited to the above-described method of forming a covalently crosslinked structure. Is a method generally called a polymer alloy in which a thermoplastic elastomer such as an ethylene-α-olefin copolymer elastomer, an ethylene-α-olefin cross-linked copolymer elastomer, and a styrene-ethylene-block copolymer elastomer is blended. Can also be used. Further, by using a resin having an ionic crosslinking structure such as a polyethylene ionomer resin, elasticity can be imparted.

  The core 3 is made of an elastic body in which a covalent cross-linking structure is formed between molecules of the low density polyethylene resin. As the material of the core 3, in addition to the low density polyethylene, polyethylene resin such as ultra low density polyethylene, medium density polyethylene, high density polyethylene, linear low density polyethylene, polypropylene resin, ethylene vinyl acetate resin, polyethylene terephthalate resin Polytrimethylene terephthalate resin, polybutylene terephthalate resin, polybutylene naphthalate resin, polycyclohexane terephthalate resin, polyester resin such as polyethylene naphthalate resin, nylon 6, nylon 66, nylon 610, nylon 612, nylon 11, nylon 12, polyamide resins such as nylon 46 can be used alone or in combination. Examples of the crosslinking agent that forms a covalently crosslinked structure include dicumyl peroxide, 2,5-dimethyl-2,5-bis-tertiary butyl peroxyhexene, 1,3-bis-tertiary peroxy as described above. An organic peroxide such as isopropylbenzene can be used.

  Next, a method for manufacturing the brush piece 1 will be described. In the brush piece 1, a foaming agent and a crosslinking agent are mixed in advance in the ethylene vinyl acetate resin that forms the outer layer portion 2, while a crosslinking agent is blended in the low-density polyethylene resin that forms the core portion 3. The outer layer portion 2 and the core portion 3 are simultaneously extruded through a die attached to the tip of an extruder (not shown). After extrusion, the film is formed by stretching in the longitudinal direction with a stretching machine while being heated, and after cooling and solidifying by cooling in a process called annealing. By the way, in general, resin molding techniques include melt molding, solid layer molding, cast molding, injection molding, vacuum molding, pressure forming, press molding, and the like. This is called extrusion molding.

  The above-described method of stretching in the longitudinal direction is called uniaxial stretching. Uniaxial stretching is a processing method in which stretching stress is applied only in one direction. In the direction parallel to the stretching direction, molecular orientation occurs, so that the tensile strength is remarkably improved, but the direction perpendicular to the stretching direction is tensile. Since the strength is not improved, it has the property of being easily torn in a direction parallel to the stretching direction. Therefore, the brush piece 1 can form the tip crack part 4. The molecular orientation means that the linear molecules are arranged in a certain direction by the action of external force in a molten or solid state. Moreover, the formation method of the front crack part 4 is formed by subdividing the predetermined length of the both ends of the brush piece 1 with the subdivision machine which has the division | segmentation blade and cutter of predetermined rotation speed.

  When the brush piece 1 is not stretched as described above, molecular orientation does not occur, so it is difficult to form the pre-cracked portion 4 on the brush piece 1, but the slit 6 is formed using a cutter or the like. be able to.

  The operation | movement and effect | action of the brush piece 1 which comprises cleaning brushes, such as a wheel of this invention, are as follows.

  The outer layer 2 constituting the brush piece 1 is formed of a foam, and since the ethylene vinyl acetate resin is used as the material of the outer layer 2, the outer layer 2 in contact with the surface to be cleaned is foamed. It has been done. Therefore, the brush piece 1 can absorb and disperse a reaction force such as an impact force from the surface to be cleaned, and can come into contact with the surface to be cleaned more flexibly, and the brush piece 1 can be reduced in weight. For this reason, even if the brush piece 1 is pressed deeply into contact with the surface to be cleaned, the vehicle body that is the surface to be cleaned is not damaged. Further, since the outer layer portion 2 formed in the foam absorbs and disperses reaction force such as impact force from the surface to be cleaned, the brush piece 1 is not broken due to buckling or the like. It can have high durability. Further, since the ethylene vinyl acetate resin has a water absorption rate of 0%, water content during the washing of the brush piece 1 can be suppressed. Therefore, since the brush piece 1 does not freeze in winter and the brush piece 1 that has been hardened by freezing does not come into contact with the vehicle body, the vehicle body can be prevented from being damaged due to scratches, and the damage prevention effect Will further improve.

  Moreover, since the low density polyethylene resin whose hardness is larger than the outer-layer part 2 is used as a material of the core part 3 which comprises the brush piece 1, the brush piece 1 hold | maintains the hair and waist which the said material has. At the same time, the fluff of the core 3 can be imparted to the surface to be cleaned. Moreover, since the low density polyethylene resin is used for the core part 3, the brush piece 1 has characteristics, such as a water absorption rate of 0% and a low price.

  Further, since the outer layer part 2 and the core part 3 are formed of an elastic body having a shape restoring force, elasticity is imparted to the brush piece 1. That is, when the brush piece 1 is brought into contact with the surface to be cleaned, after being bent and deformed, and separated from the surface to be cleaned, the brush piece 1 is restored from the bent state to the original state without being bent. Therefore, since the brush piece 1 does not continue to contact the surface to be cleaned in a state of being bent and deformed, the brush piece 1 breaks, breaks, breaks and breaks at the bent and deformed portion. There is nothing. Therefore, the durability of the brush piece 1 is greatly improved.

  Further, since the side end portion 7 of the cross section of the brush piece 1 is formed in a substantially round shape, the side end portion 7 does not have a corner portion, so that it is possible to suppress the adhesion of scratches to the surface to be cleaned. .

  Further, since the cross section of the brush piece 1 is formed in a wave shape, a curved portion 5 is formed in the wave shape cross section. Therefore, water droplets or the like of cleaning water can be temporarily stored in the wave-shaped curved portion 5 of the brush piece 1. In addition, since the curved portion 5 contacts the surface to be cleaned in the wave-shaped cross section, the curved portion 5 that has contacted accurately removes and removes dirt and the like on the surface to be cleaned. Therefore, it is possible to greatly improve the cleaning performance.

  Further, since the brush piece 1 has the front cracked portion 4 or the slit 6 at both ends in the longitudinal direction, the front cracked portion 4 or the slit 6 of the brush piece 1 has a front cracked portion 4 or a slit against the surface to be cleaned. Compared with the case where 6 is not formed, the brush piece 1 comes into contact more flexibly and also comes into contact with fine uneven portions of the surface to be cleaned. Therefore, it is possible to dramatically improve the cleaning performance without damaging the vehicle body that is the surface to be cleaned.

  The shape of the brush piece 1 is not limited to the long shape having the cross section as described above, but the cross-sectional shape is a polygonal shape such as a substantially round shape, a triangle shape, a quadrangular shape, a hexagonal shape, or an M shape, an H shape, and a saw shape. It may be a cross, crescent, etc.

  Further, the structure for mounting the brush piece 1 to the base 12 is not particularly limited, and other than the structure as described above, it can be set as appropriate according to the purpose of use. For example, a flocking hole for planting the brush piece 1 is provided on the surface of the pedestal 12, the brush piece 1 is sandwiched between the flocking hole with staples, the brush piece 1 is folded in half, and driven into the bottom surface of the flocking hole. A round wire brush fixed to the base 12 or a brush piece 1 is pressed against a flocked hole with a thin flat plate, the brush piece 1 is folded in half, and the flat plate is attached to the bottom surface of the flocked hole so as to fit the inner peripheral surface of the flocked hole. The brush piece 1 is fixed to the pedestal 12 and the brush piece 1 is pressed against the flocking hole with a pulling line such as nylon as described above, the brush piece 1 is folded in half, and the pulling line is placed on the pedestal. A retractable brush or the like for fixing the brush piece 1 to the pedestal 12 along the inner peripheral surface of the twelve can also be adopted. The flocking holes as described above may be provided on the outer peripheral surface of the pedestal 12 at equal intervals or in a staggered manner. The diameter of the flocked hole is set in a timely manner according to the flocked amount of the brush piece 1. Furthermore, the central portion of the brush piece 1 in the longitudinal direction is folded and fixed to the pedestal 12 with a rivet or the like, or the groove portion is formed on the surface of the pedestal 12, and then the brush piece 1 is fixed to the groove portion with a stopper. A form or a form in which a channel brush in which the brush piece 1 is folded into the groove is inserted and fixed can also be adopted.

A cleaning agent and water are sprayed from the nozzle 103 to the surface to be cleaned, and the upper surface and side surfaces of the vehicle body are cleaned by the cleaning brush 105 and the wheel is cleaned by the cleaning brush 10 such as a wheel. After cleaning, the surface to be cleaned is dried by a dryer 104 which is a drying means of the car wash machine 100.

  The operation and action of the car wash machine 100 provided with the washing brush 10 such as a wheel of the present invention are as follows.

  Since the car wash machine 100 is equipped with a cleaning brush 10 such as a wheel having high cleaning performance without damaging the surface to be cleaned, it strongly abuts against the surface to be cleaned without causing scratches. Can be made. For this reason, the car wash machine 100 sets the cleaning brush 10 such as a wheel to high speed rotation, and even when the cleaning time is set to a short time, the surface to be cleaned is not attached to the surface to be cleaned, and there is no cleaning residue. Detergency is added. Further, even when the rotation of the cleaning brush 10 such as a wheel is suddenly changed from a low-speed rotation to a high-speed rotation or the like, the same action as described above is given to the car wash machine 100. Therefore, it is possible to provide the car wash machine 100 that can exhibit very high cleanability without damaging the vehicle body that is the surface to be cleaned. Further, the cleaning brush 10 such as a wheel mounted on the car wash machine 100 has a reinforcing member having a hardness higher than that of the brush piece formed on the outer peripheral portion of the brush portion.
