  An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are a side view and a perspective view showing a car washer WA according to an embodiment of the present invention. The car wash WA includes a remote panel 7 (operation unit) and the car wash main body 1.

  The remote panel 7 is arranged along the approach path R of the vehicle CA to be cleaned. The vehicle to be washed CA stops in front of the remote panel 7, and the user sets the washing conditions by operating the remote panel 7.

  With the buttons provided on the remote panel 7, it is possible to set conditions for car washing using a liquid agent used for shampooing, waxing, water-repellent coating, and the like. The remote panel 7 can also be used to set equipment such as a front guard, a fender pole, a side mirror, a rear wiper, and a roof carrier.

  When the driver's seat of the vehicle to be cleaned CA is on the left side, a side brush 30 described later is arranged on the right side (passenger seat side) of the vehicle to be cleaned CA by operating the remote panel 7.

  The car washer body 1 is formed as a portal having two left and right opposite stand portions 90 and a ceiling portion 91 connecting the upper ends of the stand portions 90. The ceiling portion 91 has an eave portion 40 protruding from the stand portion 90 toward the entry side of the vehicle CA to be cleaned. The eaves portion 40 is provided rotatably about the shaft portion 40a.

  A pair of left and right rails 2 are laid on the ground G, and wheels 3 provided on the bottom surface of the stand unit 90 are arranged on the rails 2. As a result, the car washer body 1 stands on the rail 2, travels on the rail 2 by driving of a traveling motor (not shown), and moves back and forth with respect to the vehicle CA to be washed.

  The stand unit 90 is provided with a tank storage unit 29 that stores a plurality of storage tanks (not shown) that store various liquid agents such as detergents and waxes. Above the tank storage section 29, a distribution pipe section 28 for distributing the liquid agent from each liquid storage tank is provided. The distribution pipe section 28 includes first and second water purification nozzles 11 and 13, first and second detergent nozzles 12 and 15, water-repellent coating nozzles 14, and wax nozzles 16 each having an electromagnetic valve (not shown). Derived through

  The first and second water purification nozzles 11 and 13 are disposed on the inlet surface 1a side and the outlet surface 1b side of the car wash machine main body 1, respectively, and inject the wash water to the vehicle CA to be washed. The first and second detergent nozzles 12 and 15 are disposed on the inlet surface 1a side and the outlet surface 1b side of the car washer body 1, respectively, and inject the detergent to the vehicle CA to be washed. The water-repellent coating nozzle 14 and the wax nozzle 16 are arranged on the exit surface 1b side of the car wash machine body 1. The water-repellent coating nozzle 14 injects a liquid of a water-repellent coating agent to the vehicle CA to be cleaned. The wax nozzle 16 injects liquid wax to the vehicle CA to be cleaned.

  A water tank 70 is provided in one of the stand portions 90. The water tank 70 is connected to the distribution pipe section 28 via a pipe (not shown). The size of the water tank 70 in the left-right direction is formed smaller than the size in the front-rear direction, and is stored in the stand unit 90. In the water tank 70, for example, about 110 liters of washing water is stored.

  Further, a vehicle detection sensor 9 is provided on the entrance surface 1a side of the stand section 90. The vehicle detection sensor 9 includes a photoelectric sensor having a light-emitting unit and a light-receiving unit, an ultrasonic sensor, and the like, and detects a vehicle length and an outer shape of the vehicle CA to be washed entering the car wash machine body 1.

  The car washer body 1 is provided with a blower 20 that generates an airflow to dry the vehicle CA to be cleaned. A plurality of blowing nozzles (drying units) including a side blowing nozzle 22 and a top blowing nozzle 21 are connected to the blower 20. The side blowing nozzles 22 are provided on both the stand portions 90, respectively, and blow the air toward the side surface of the vehicle CA to be cleaned. The top blowing nozzle 21 is provided on the ceiling 91 and blows air toward the upper surface of the vehicle CA to be cleaned.

  The top blowing nozzle 21 is disposed closer to the entrance surface 1a of the car wash machine body 1 than the side blowing nozzle 22 is. Further, the top blowing nozzle 21 and the side blowing nozzle 22 are arranged between a top brush 4 and a side brush 30 described later.

  A plurality of rotations including a top brush 4, a side brush 5 (first side brush), a rocker brush 6, and a side brush 30 (second side brush) that slide and brush on the vehicle to be cleaned CA are provided on the car wash machine body 1. A brush is provided.

  The side brushes 5 are provided on a pair of left and right sides on the exit surface 1b side of the car wash machine body 1. In addition, the side brush 5 has a rotating shaft (not shown) arranged vertically, and cleans the front side of the vehicle to be cleaned CA and the front side cleaning area T1 (see FIG. 9) of the vehicle to be cleaned CA.

  The top brush 4 is arranged on the entrance surface 1a side of the car wash machine body 1 with respect to the side brush 5. Further, the top brush 4 arranges a rotating shaft (not shown) in a horizontal direction and moves up and down along the upper surface of the vehicle to be cleaned CA to clean the upper surface of the vehicle to be cleaned CA. The rocker brush 6 is disposed between the side brush 5 and the top brush 4, and has a rotating shaft (not shown) arranged in a vertical direction to clean lower portions on both side surfaces of the vehicle CA to be cleaned.

  The side brush 30 is disposed on the opposite side of the side brush 5 with respect to the top brush 4, and one is provided outside the entrance surface 1 a of the car wash machine body 1. The side brush 30 has a rotating shaft (shaft 30a) arranged in the up-down direction, and cleans a rear cleaning area T2 (see FIG. 10) of the side surface of the vehicle CA and the rear surface of the vehicle CA.

  Each rotating brush has a plurality of cleaning materials such as cloth and sponge attached to a peripheral surface of a shaft forming a rotating shaft. For this reason, the rocker brush 6, the side brush 5, and the side brush 30 having the rotating shafts arranged in the vertical direction have a small diameter because the cleaning material hangs down when the rotation is stopped, and have a large diameter because the cleaning material spreads by centrifugal force during rotation. The side brush 30 is made of a different material or color from the side brush 5.

  FIG. 3 shows a schematic front view of the car wash body 1. Inside the eaves portion 40 (see FIG. 2), a rail 26 (guide portion) extending in the left-right direction is provided. The side brush 30 is held by a holding portion 35 running on the rail 26. Thereby, the side brush 30 is arranged so as to be movable in the left-right direction.

  FIG. 4 shows a front view of the upper part of the side brush 30. The holding portion 35 is formed of a plurality of metal plates, and surrounds the front and rear surfaces of the rail 26 by a pair of opposing walls 35a that face each other. The holding portion 35 is provided with a driving wheel 27 that rolls on the rail 26, and driven rollers 34a to 34e.

  The drive wheel 27 is axially supported by the holding portion 35 with the axial direction arranged horizontally. The drive wheel 27 rolls on the upper surface 26 a of the rail 26 by driving a moving motor 36 attached to the holding unit 35. The upper surface 26a of the rail 26 is formed with inclined surfaces at front and rear ends, and the peripheral surface of the drive wheel 27 is formed in a V shape along the front and rear inclined surfaces of the upper surface 26a. Thus, the drive wheels 27 can stably roll on the upper surface 26a of the rail 26.

  The driven roller 34a is supported by the holding portion 35 with the axial direction inclined with respect to the horizontal, and is provided in a pair in front and rear along the front and rear inclined surfaces of the upper surface 26a. The driven rollers 34b and 34c are horizontally supported in the axial direction and are supported by the shaft supporting portion 25, and roll on the lower surface 26b of the rail 26. The driven rollers 34d and 34e are vertically supported in the axial direction and are supported by the holding portion 35 to roll on the side surface 26c of the rail 26.

  A shaft support 25 that supports the side brush 30 is provided on the facing wall 35a. The shaft 30a forming the rotation axis of the side brush 30 is inserted into a hollow rod 30b having a rectangular horizontal cross section, and is rotatably supported by a bearing (not shown) arranged in the rod 30b. The shaft 30a is connected to a rotation motor (not shown) provided in the holding unit 35, and the side brush 30 rotates around a rotation shaft extending vertically by driving the rotation motor.

  A shaft portion 30d protrudes from front and rear surfaces of the rod 30b, and a bearing 25a fitted to the shaft portion 30d is provided on the shaft support portion 25. Thereby, the holding part 35 holds the side brush 30 so as to be able to tilt in the left-right direction about the shaft part 30d.

  The shaft support 25 is provided with a tilt sensor 25b and a tilt sensor 25c, each of which is a proximity switch, above and below the shaft 30d. An opposing member 39b is disposed on the rod 30b above the inclination sensor 25b, and an opposing member 39c is disposed below the inclination sensor 25c.

  The facing member 39b and the facing member 39c face the inclination sensor 25b and the inclination sensor 25c, respectively, and detect the amount of inclination of the side brush 30. The side brush 30 that moves in the left-right direction by driving the moving motor 36 is inclined when it comes into contact with the vehicle CA to be cleaned. Then, when the tilt sensor 25b faces the facing member 39b, the moving motor 36 is stopped, and the side brush 30 is disposed at a desired tilt amount at the time of cleaning. When the inclination sensor 25c faces the opposing member 39c, the movement motor 36 is stopped, and the side brush 30 is arranged at a desired inclination amount during cleaning.

  That is, when cleaning the right side surface of the vehicle CA to be cleaned, the inclination sensor 25b detects that the side brush 30 has reached a desired inclination amount facing the opposing member 39b in the drawing. When cleaning the left side surface of the vehicle CA to be cleaned, the inclination sensor 25c detects that the side brush 30 has reached a desired inclination amount facing the opposing member 39c in the figure.

  Further, a new counter member may be added to the right side of the counter members 39b and 39c, and the abnormality of the inclination amount of the side brush 30 may be detected by the increased counter member. When an abnormality is detected, the side brush 30 can be evacuated from the vehicle CA by the moving motor 36.

  The holding portion 35 is provided with a double-acting air cylinder 32 disposed above the shaft portion 30d. The air cylinder 32 has a cylindrical cylinder tube 32b and a cylinder rod 32a, and the tip of the cylinder rod 32a is rotatably connected to the upper end of the rod 30b. A pipe 33 is connected to a front end and a rear end of the cylinder tube 32b, and air is supplied through one of the pipes 33. As a result, the cylinder rod 32a is changed between an extended state and a contracted state, and the air cylinder 32 urges the side brush 30 in the circumferential direction of the shaft portion 30d.

  That is, when the left side surface of the vehicle to be cleaned CA is cleaned, the cylinder rod 32a extends, and the side brush 30 abutting on the vehicle to be cleaned CA tilts clockwise in the figure against the urging force of the air cylinder 32. When the right side surface of the vehicle to be cleaned CA is cleaned, the cylinder rod 32a contracts, and the side brush 30 abutting on the vehicle to be cleaned CA tilts counterclockwise in the figure against the urging force of the air cylinder 32.

  Thus, the side brush 30 can be urged by the one air cylinder 32 in both the left and right directions. Further, when the side brush 30 is urged in both the left and right directions by the two coil springs, the elastic force due to expansion and contraction from the free length of the coil spring to the neutral position is canceled. For this reason, the urging force on the side brush 30 inclined from the neutral position is small, and it is difficult to obtain a large urging force.

  On the other hand, the air cylinder 32 can obtain a large urging force in the left and right directions with respect to the side brush 30 by switching the air supply direction. Therefore, it is possible to easily realize the side brush 30 having a large pressing force on both side surfaces of the vehicle to be cleaned CA and a large cleaning power. The air cylinder 32 may be a single-acting type, but if it is a double-acting type, the biasing force in both the left and right directions can be obtained by air pressure. For this reason, even if the inclination amount of the side brush 30 fluctuates, the urging force can be stabilized, and the pressing force of the side brush 30 against the vehicle CA to be cleaned can be made uniform.

  Note that the side brush 5 is also arranged movably in the left-right direction by the same configuration. At this time, since the left and right side brushes 5 are arranged in a pair, the inclination sensors 25b and 25c detect inclination in one direction. Further, a coil spring for urging the side brush 5 in one direction of inclination is provided instead of the air cylinder 32.

  The shaft 30a of the side brush 30 is provided detachably with respect to the rod 30b. Further, the eaves portion 40 is provided on the ceiling portion 91 so as to be rotatable about a shaft portion 40a (see FIG. 1). For this reason, as shown in FIG. 5, when the side brush 30 is removed and the eaves portion 40 is rotated downward, the front-rear width of the car wash machine main body 1 can be reduced. Thus, when the car wash machine body 1 is transported, the car wash machine body 1 can be placed on the carrier with the front-rear direction of the car wash machine body 1 arranged in the left-right direction of the carrier of the transport vehicle.

  6 and 7 show a top view and a perspective view of the front right portion of the car wash machine main body 1. The car washer body 1 is provided with a water splash cover 51 projecting from the side end portions of both stand portions 90 toward the entry side of the vehicle to be washed CA and extending vertically. The water splash cover 51 is formed of an acrylic plate or the like, and shields the water splash of the side brush 30 moving below the eaves portion 40 in the left-right direction. Thereby, scattering of the washing water by the side brush 30 can be reduced.

  The right stand portion 90 is provided with a support portion 8a protruding along the splash cover 51 toward the entry side of the vehicle CA to be cleaned, and an operation panel 8 is provided at a tip of the support portion 8a. The operation panel 8 (operation unit) has a plurality of operation buttons (not shown), and can perform input operations such as a manual instruction to start washing and an instruction to stop washing.

  The operation panel 8 is inclined toward the entry side of the vehicle CA to be washed toward the center of the car wash machine body 1 in the left-right direction. As a result, the front-rear width of the car washer body 1 can be reduced, and interference between the side brush 30 disposed at the right end and the operation panel 8 is avoided to secure a large installation area for the operation buttons on the operation panel 8. Can be.

  In the car washer WA having the above configuration, a predetermined car wash setting is performed from the remote panel 7, and the vehicle CA to be washed is stopped at a predetermined position. At this time, by operating the remote panel 7, the side brush 30 is arranged at the initial position Y1 (see FIG. 8) on the passenger seat side (usually left side) of the vehicle CA to be cleaned. Thus, the driver can easily get off the vehicle before the start of car washing. Further, the driver may get off the vehicle before getting into the car wash machine main body 1 and set by the operation panel 8.

  When the vehicle to be washed CA stops at a predetermined position, the car wash machine body 1 moves in the front-rear direction from the car wash start position U1 (see FIG. 8), and the car wash is performed. FIGS. 8 to 10 are top views showing a state at the time of washing by the car wash machine main body 1.

  When the car wash is started, the car wash machine body 1 starts moving from the car wash start position U1 toward the rear of the vehicle CA to be washed, as shown by an arrow D1 in FIG. The vehicle detection sensor 9 detects the shape of the vehicle CA to be washed with the movement of the car washer body 1.

  At this time, the side brush 30 rotates at a lower speed than at the time of cleaning by the side brush 30. Since the side brush 30 projects more toward the entrance side of the vehicle to be cleaned CA than the stand 90, a person may be present near the side brush 30. For this reason, there is a risk of injury if cleaning is performed by rotating the stopped side brush 30 at high speed. Therefore, by rotating the side brush 30 at a low speed before washing, it is possible to recognize in advance that high-speed rotation will be performed, thereby preventing danger.

  The top brush 4 moves up and down along the shape of the vehicle to be cleaned CA detected by the vehicle detection sensor 9. Thereby, the upper surface of the vehicle CA to be cleaned is cleaned.

  When the side brush 5 is disposed at the front end of the vehicle to be cleaned CA detected by the vehicle detection sensor 9, the car wash machine body 1 stops, and the left and right side brushes 5 rotate and move in the left and right direction. Thereby, the front surface of the vehicle to be cleaned CA is cleaned.

  When the cleaning of the front surface of the vehicle to be cleaned CA is completed, the left and right side brushes 5 are separated, and the car wash machine body 1 moves toward the rear of the vehicle to be cleaned CA again as shown in FIG. Thus, the front portion of the side surface of the vehicle to be cleaned CA is cleaned by the side brush 5.

  At this time, the side brush 5 rotates in a direction opposite to the traveling direction in a direction of sliding on the vehicle to be cleaned CA. That is, the left side brush 5 rotates in the rotation direction V1 (counterclockwise in the figure), and the right side brush 5 rotates in the rotation direction V2 (clockwise in the figure).

  When the top brush 4 is washed to the rear end of the vehicle CA to be washed as shown in the figure, the car washer body 1 stops, and the top brush 4 and the side brush 5 stop. As a result, the cleaning of the upper surface of the vehicle to be cleaned CA is completed, and the cleaning of the front cleaning area T1 on both sides is completed.

  At this time, assuming that the center-to-center distance between the top brush 4 and the side brush 30 is L, the radius of the top brush 4 is R1, and the radius of the side brush 30 is R2, the car washer body 1 projects behind the vehicle CA to be cleaned. The distance W is approximately L + R2-R1.

  Next, as shown in FIG. 10, the car washer body 1 moves toward the front of the vehicle CA to be washed, and stops when the side brush 30 is disposed at the end of the washing area T1. Then, the side brush 30 moves along the vehicle to be cleaned CA as shown by the arrow E1, and cleans the cleaning area T2 at the rear of both sides of the vehicle to be cleaned CA and the rear surface of the vehicle CA to be cleaned.

  That is, the car washer body 1 moves toward the rear of the vehicle to be cleaned CA, and the side brush 30 cleans the cleaning area T2 on the left side of the vehicle to be cleaned CA. Next, the car washer body 1 stops, the side brush 30 moves in the left-right direction, and the rear surface of the vehicle CA to be cleaned is cleaned. Next, the car washer body 1 moves toward the front of the vehicle to be cleaned CA, and the side brush 30 cleans the cleaning area T2 on the right side of the vehicle to be cleaned CA.

  FIGS. 11 to 14 are front views showing the cleaning state by the side brush 30 at this time. When cleaning by the side brush 30 starts, air is supplied to the air cylinder 32 in the direction in which the cylinder rod 32a extends. Then, as shown in FIG. 11, the holding unit 35 is guided and moved rightward from the left end of the rail 26 by the driving of the moving motor 36, and the side brush 30 contacts the left side surface of the vehicle CA to be cleaned.

  As a result, the side brush 30 tilts in the left-right direction against the biasing force of the air cylinder 32, and when the side brush 30 is disposed at a predetermined tilt amount by the detection of the tilt sensor 25b, the moving motor 36 is stopped. At this time, the side brush 30 rotates in the rotation direction V3 (first rotation direction, see FIG. 10) sliding on the vehicle to be cleaned CA in the opposite direction to the traveling direction, and cleans the left side surface of the vehicle to be cleaned CA.

  When the side brush 30 is disposed behind the vehicle to be cleaned CA, the car washer body 1 stops moving. At this time, since the side brush 30 is released from the pressing force from the side surface of the vehicle CA to be cleaned, the cylinder rod 32a extends. For this reason, as shown in FIG. 12, the side brush 30 is inclined such that the lower end faces right. Then, the side brush 30 is moved rightward by the driving of the moving motor 36, and the rear surface of the vehicle CA to be cleaned is cleaned. At this time, the side brush 30 rotates in the rotation direction V3.

  When the side brush 30 reaches the substantially central portion P1 on the rear surface of the vehicle CA to be cleaned, the air cylinder 32 is supplied with air in a direction in which the cylinder rod 32a contracts. For this reason, as shown in FIG. 13, the side brush 30 is inclined such that the lower end faces the left side. The air cylinder 32 may supply air in a direction in which the cylinder rod 32a contracts at the end of the cleaning of the rear surface of the vehicle CA to be cleaned.

  Further, the rotation motor of the side brush 30 is reversed, and the side brush 30 rotates in a rotation direction V4 (second rotation direction, see FIG. 10) opposite to the rotation direction V3. Thus, the remaining rear surface of the vehicle to be cleaned CA is cleaned by the side brush 30 rotating in the rotation direction V4.

  The side brush 30 rotates in the rotation direction V3 that slides on the vehicle to be cleaned CA in the direction opposite to the traveling direction on the left half of the rear surface of the vehicle to be cleaned CA, and slides on the vehicle CA in the traveling direction in the right half. In the rotating direction V4. Therefore, when the rear wiper is provided on the vehicle to be cleaned CA, the side brush 30 slides from the support shaft of the rear wiper toward the open end to press the rear wiper against the rear surface of the vehicle to be cleaned CA. Thus, it is possible to prevent the rear wiper from being damaged by being peeled from the rear surface of the vehicle to be cleaned CA by the side brush 30 whose open end rotates.

  When the side brush 30 finishes cleaning the rear surface of the vehicle CA to be cleaned, it moves to the right end of the rail 26. At this time, the rotation motor of the side brush 30 is reversed, and the side brush 30 rotates in the rotation direction V3 (see FIG. 10).

  Further, as shown in FIG. 14, the holding portion 35 is guided and moved leftward from the right end of the rail 26 by the driving of the moving motor 36, and the side brush 30 contacts the right side surface of the vehicle CA to be cleaned. As a result, the side brush 30 tilts in the left-right direction against the biasing force of the air cylinder 32, and when the side brush 30 is disposed at a predetermined tilt amount by the detection of the tilt sensor 25b, the moving motor 36 is stopped. Then, the car washer body 1 moves forward of the vehicle to be cleaned CA, and the side brush 30 cleans the cleaning area T2 on the right side of the vehicle to be cleaned CA.

  Note that the start end of the cleaning region T2 coincides with the end of the cleaning region T1, but the start end of the cleaning region T2 may be set ahead of the end of the cleaning region T1. That is, after the cleaning of the cleaning area T1, the car wash machine body 1 may be moved forward at least until the side brush 30 is disposed at the end of the cleaning area T1.

  In addition, the cleaning area T2 on one side of the vehicle CA to be cleaned may be cleaned by the side brush 30 while the car washer body 1 moves forward after the cleaning area T1 is cleaned by the side brush 5.

  When the cleaning of the cleaning area T2 on both side surfaces by the side brush 30 is completed, the car washer body 1 moves toward the rear of the vehicle CA to be cleaned and is disposed at the drying start position U2 shown in FIG. At the drying start position U2, the rear surface of the vehicle CA to be cleaned is dried by the top blowing nozzle 21. When the car washer body 1 arranged at the drying start position U2 moves toward the front of the vehicle to be cleaned CA as shown by an arrow D2, the vehicle to be cleaned CA is dried by the top blowing nozzle 21 and the side blowing nozzle 22. .

  When the drying of the vehicle to be cleaned CA is completed by the top blowing nozzle 21 and the side blowing nozzle 22, the car wash machine body 1 moves to the rear of the vehicle to be cleaned CA, and the vehicle to be cleaned CA moves forward and retreats. At this time, when it is detected that the side brush 30 is disposed behind the rear end of the vehicle CA to be cleaned, the side brush 30 moves in the left-right direction and returns to the initial position Y1 (see FIG. 8). At this time, if the next vehicle to be washed CA is set to be washed, the initial position Y1 is changed according to the position of the passenger seat of the vehicle to be washed CA.

  Thereby, the movement of the car washer body 1 in the front-rear direction and the movement of the side brush 30 in the left-right direction are simultaneously performed, and the car washing time can be reduced. When the car wash machine body 1 described later returns to the car wash start position U1, the side brush 30 may move in the left-right direction and return to the initial position Y1 (see FIG. 8).

  When it is confirmed that the vehicle to be washed CA has exited, the car wash machine body 1 returns to the car wash start position U1, and the car wash ends. Then, during a predetermined period after the end of the car washing, the side brush 30 is previously rotated at a lower speed than at the time of washing to be dehydrated. Since the rotation is performed at a low speed, the fact that the rotation is performed at a high speed can be recognized in advance to prevent danger. In addition, it is possible to prevent the side brush 30 from freezing in winter by removing the moisture of the side brush 30.

  According to the present embodiment, the top is located between the pair of side brushes 5 (first side brushes) and one side brush 30 (second side brush) arranged on the entry side of the vehicle CA to be cleaned with respect to the side brushes 5. A brush 4 is provided. Further, the side brush 5 cleans the front cleaning area T1 on both sides of the vehicle to be cleaned CA and the front surface of the vehicle CA to be cleaned. The cleaning area T2 at the rear of both sides of the vehicle to be cleaned CA and the rear surface of the vehicle to be cleaned CA are cleaned by the side brush 30. For this reason, the distance W of the car washer body 1 protruding rearward of the vehicle to be cleaned CA can be reduced. Thereby, the front-back stroke of the car wash machine main body 1 can be shortened, and the installation space of the car wash machine WA can be saved.

  Further, the side brush 30 that can be tilted in the left-right direction is urged by the air cylinder 32, and the urge direction of the air cylinder 32 is different between when the right side of the vehicle to be cleaned CA is washed and when the left side is washed. Thus, the side brush 30 can be urged by the one air cylinder 32 in both the left and right directions. Further, it is possible to easily realize the side brush 30 having a large pressing force on both side surfaces of the vehicle to be cleaned CA and a large cleaning power.

  The tilt sensor 25b and the tilt sensor 25b are provided above and below the shaft 30d. This makes it possible to easily detect the amount of inclination of the side brush 30 during cleaning.

  Further, since the air cylinder 32 is disposed above the shaft portion 39d, interference between the pipe 33 of the air cylinder 32 and the cleaning material of the side brush 30 can be prevented.

  Further, since the air cylinder 32 is a double-acting type, the pressing force of the side brush 30 against the vehicle CA to be cleaned can be made uniform.

  The ceiling portion 91 has an eave portion 40 projecting from the stand portion 90 toward the entry side of the vehicle CA to be cleaned, and the rail 26 (guide portion) extends left and right and is disposed inside the eave portion 40. Thus, the side brush 30 that moves in the left-right direction can be easily realized.

  Further, the side brush 30 is provided detachably with respect to the holding portion 35, and the eave portion 40 is provided rotatably about the shaft portion 40a. Thereby, the front-rear width of the car wash machine main body 1 can be reduced in size and can be easily transported.

  Further, an operation panel 8 is provided at a tip end of a support portion 8a protruding from the stand portion 90 toward the entry side of the vehicle CA to be cleaned. Thereby, the operation panel 8 is not closed by the side brush 30, and the operation panel 8 can be easily operated.

  Further, the operation panel 8 is inclined toward the entry side of the vehicle CA to be washed toward the center in the left-right direction of the car washer body 1. Thereby, the front-rear width of the car wash machine main body 1 can be reduced, and the installation space of the car wash machine WA can be further reduced. Further, the interference between the side brush 30 provided at one end and the operation panel 8 can be avoided, and a large installation area for the operation buttons on the operation panel 8 can be secured.

  In addition, since the water cover 51 is provided so as to protrude from the side end of the stand portion 90 toward the entry side of the vehicle to be cleaned CA and extend vertically, the scattering of the cleaning water by the side brush 30 can be reduced.

  Further, since the washing water tank 70 is provided in the stand section 90, the installation space for the car washer WA can be further reduced.

  Further, since the air blowing nozzles (21, 22) are arranged between the side brush 5 and the side brush 30, the distance W of the car washer body 1 protruding rearward of the vehicle to be cleaned CA can be reliably reduced. . Therefore, the installation space of the car washer WA can be more reliably saved.

  In the present embodiment, the rail 26 may be arranged to be inclined in the front-rear direction, and the side brush 30 may be inclined upward toward the front of the vehicle CA to be cleaned as shown in FIG. Accordingly, the side brush 30 is arranged along the rear surface of the vehicle CA to be cleaned at the time of cleaning the rear surface of the vehicle CA to be cleaned, and the cleaning power can be improved.
