  First guide rollers 62A and 62B arranged vertically are pivotally supported on the elevating parts 61A and 61B, respectively. An auxiliary roller 62C is pivotally supported between the first guide rollers 62A and 62B. The first guide rollers 62A and 62B rotate around a rotation axis extending in the left-right direction, and the auxiliary roller 62C rotates around a rotation axis extending in the front-rear direction. Accordingly, the first guide rollers 62A and 62B roll on the rails 59A and 59C. Further, the auxiliary roller 62C rolls on the connecting portion 59B. Therefore, the elevating parts 61A and 61B can be smoothly moved up and down along the guide rail 59.

  5, FIG. 6, and FIG. 7 are a front sectional view, a top sectional view, and a left side sectional view of the left side lifting unit 61B. The elevating part 61B includes a box-shaped holder 70, and the first guide rollers 62A and 62B and the auxiliary roller 62C are attached to the left side surface 70b of the holder 70.

  The inside of the holder 70 is partitioned up and down via a guide plate 72, and the guide plate 72 has inclined surfaces 72a and 72b at both front and rear ends of a horizontal plane portion 72b. The inclined surface 72a is inclined forward and upward, and the inclined surface 72c is inclined upward and backward.

  A support portion 43 is disposed on the upper surface of the guide plate 72. The support portion 43 includes a pair of swing rollers 43 a and 43 b at one end in the holder 70. The rotation shafts of the swing rollers 43a and 43b extend in the left-right direction, and the swing rollers 43a and 43b roll on the guide plate 72 in the front-rear direction.

  Further, the other end of the support portion 43 protrudes to the outside of the holder 70 through an opening 71 that opens to a part of the right side surface 70a of the holder 70, and supports the shaft 4B. Thereby, the support part 43 is rock | fluctuated in the front-back direction integrally with the top brush 4 by rocking | fluctuating roller 43a, 43b. Thereby, the rocking | fluctuation mechanism of the top brush 4 can be reduced in size up and down.

  The swing rollers 43a and 43b are shifted in the front-rear direction and the left-right direction, and the swing roller 43a is positioned in front of and on the right side of the swing roller 43b. Thereby, the support part 43 can be smoothly moved back and forth along the guide plate 72. The guide plate 72 is provided with a detection unit 45. The detection unit 45 detects that the swing roller 43b is disposed at a predetermined position on the inclined surface 72c, and determines an abnormal load on the top brush 4.

  Moreover, the support part 43 is connected with the bottom face 70c of the holder 70 via the coil spring 44 which is an elastic urging member. Thereby, the support part 43 is hold | maintained in the state urged | biased by the perpendicular direction downward. The upper end of the coil spring 44 is hooked by a hook portion 43c extending from the support portion 43 at an intermediate position in the front-rear direction and the left-right direction of the swing rollers 43a, 43b. The lower end of the coil spring 44 is hooked on a vertical reference plane h (see FIG. 7) in the center in the front-rear direction of the flat surface portion 72b at an intermediate position between the boundaries 72e and 72f between the inclined surfaces 72a and 72c and the flat surface portion 72b. ing.

  A through hole 73 is formed at the center of the guide plate 72, and the coil spring 44 passes through the through hole 73. Moreover, the opening part 71 opened to the right side surface 70 a of the holder 70 also extends and opens in the front-rear direction, and the movement of the support part 43 in the front-rear direction is not restricted by the contact between the holder 70 and the support part 43. .

  In the neutral state in which the top brush 4 is in an unloaded state, the swing roller 43a is disposed on the boundary 72e, and the swing roller 43b is disposed on the boundary 72f. As a result, unless an external force of a predetermined value or more is applied to the support portion 43 in the front-rear direction, the support portion 43 does not ride on the inclined surface 72 a or the inclined surface 72 c against the urging force of the coil spring 44. Further, even when the support portion 43 rides on the inclined surfaces 72a and 72c, when the external force applied to the support portion 43 disappears, the support portion 43 returns to the neutral position by the urging force of the coil spring 44.

  Therefore, when the external force to swing the top brush 4 in the front-rear direction is small, the biasing force of the coil spring 44 can suppress the swing of the top brush 4 and maintain the neutral state. As a result, it is possible to suppress fluttering and blurring of the top brush 4 caused by variations in the brush material, roundness of the brush pipe, how water is contained in the brush, and accuracy of brush installation. Therefore, the rotation of the top brush 4 can be stabilized and the occurrence of unwashed residue can be suppressed.

  The coil spring 44 may be omitted. Also in this case, since the swing roller 43a is disposed on the boundary 72e and the swing roller 43b is disposed on the boundary 72f, the support portion 43 is inclined even if a predetermined weak external force is applied in the front-rear direction. The neutral state can be maintained without riding on 72a. Further, even when the support portion 43 rides on one of the inclined surfaces 72a and 72c, when the external force applied to the support portion 43 is lost, one of the swing rollers 43a and 43b rolls the inclined surfaces 72a and 72c downward. Then, the support part 43 returns to the neutral position.

  8-10 is explanatory drawing which shows operation | movement of the support part 43. As shown in FIG. As shown in FIG. 8, when there is no external force applied to the support part 43, the upper end of the coil spring 44 is located on the reference plane h, and a neutral state is maintained.

  As shown in FIG. 9, when an external force is applied to the support portion 43 in the backward direction, the swing roller 43b rides on the inclined surface 72c against the urging force of the coil spring 44. However, in the state of FIG. 9, the swing roller 43b does not exceed a predetermined position set in advance, so that the detection unit 45 determines that an abnormal load is not applied to the top brush 4.

  Further, as shown in FIG. 10, when a larger external force is applied to the support portion 43 than in the state of FIG. 9, the support portion 43 rides on the inclined surface 72c more greatly. At this time, the detection unit 45 detects that the swing roller 43b has exceeded a predetermined position, and determines that an abnormal load is applied to the top brush 4. When the detection unit 45 detects an abnormal load, the driving of the top brush 4 is stopped. Thereby, the overload by contact | abutting with the to-be-cleaned vehicle CA of the top brush 4 can be suppressed. Therefore, cleaning is performed with the top brush 4 lightly in contact with the vehicle CA to be cleaned, and the vehicle can be prevented from being damaged by an abnormal load of the top brush 4.

  According to this embodiment, the swing rollers 43a and 43b of the support portion 43 that pivotally supports the top brush 4 roll back and forth on the guide plate 72 provided on the elevating portion 61B, and the top brush 4 swings back and forth. To do. Accordingly, it is possible to provide the car wash machine WA that can swing the top brush 4 in the front-rear direction while downsizing the swing mechanism of the top brush in the vertical direction.

  Further, the guide plate 72 has inclined surfaces 72a and 72c whose front and rear end portions are inclined upward, and swings to one of the inclined surfaces 72a and 72c unless an external force exceeding a predetermined value is applied to the top brush 4 in the front-rear direction. The rollers 43a and 43b do not ride up. For this reason, the small swing of the top brush 4 in the front-rear direction is suppressed, and the top brush 4 can be prevented from fluttering and blurring, and the rotation of the top brush can be stabilized.

  In addition, a detection unit 45 that detects the swing position of the swing roller 43b is provided, and the detection unit 45 detects that the swing rollers 43a and 43b are arranged at predetermined positions on the inclined surfaces 72a and 72c, and the top brush. 4 is detected. Thereby, when the detection part 45 discriminate | determines the abnormal load of the top brush 4, it can stop driving of the top brush 4, can suppress damaging a vehicle with the top brush 4, and can wash a car safely.

  Further, the rotary motor 60 is arranged on one side with respect to the top brush 4, and the elevating part 61 </ b> B and the support part 43 are arranged on the other side, so that the support part is caused by vibration when the rotary motor 60 is driven. 43 can be prevented from swinging in the front-rear direction.

  A pair of rocking rollers 43a and 43b are arranged side by side, the guide plate 72 has a horizontal flat portion 72b between the front and back inclined surfaces 72a and 72c, and the rocking roller 43a is not loaded when the top brush 4 is unloaded. , 43b are arranged on boundaries 72e, 72f between the inclined surfaces 72a, 72c and the plane portion 72b. As a result, when a weak external force is applied in the forward direction, the swing rollers 43a and 43b do not ride on the inclined surface 72a and remain in a neutral state. When the external force applied to the support portion 43 is lost, one of the swing rollers 43a and 43b rolls down the inclined surfaces 72a and 72c to return to the neutral state.

  For this reason, with a simple structure, when the external force for swinging the top brush 4 in the front-rear direction is small, the swing of the top brush 4 can be suppressed and the neutral state can be maintained.

  Further, the top brush 4 is formed by attaching a cloth brush body to the peripheral surface of the shaft 4B forming the rotating shaft 4A. Accordingly, the detection unit 45 can determine an abnormal load on the top brush 4 even in a cloth brush with an unstable circulating current applied to the top brush 4.
