On the other hand, the state shown in FIGS. 7 and 10 means that when the nozzle bracket 20 is rotated 180 degrees in the circumferential direction of the piston 12 and the nozzle bracket 20 is attached to the bumper bracket 30, the bumper bracket 30 Since the rib 34c on the lower surface 34 comes to the position of the guide portion 23c of the nozzle bracket 20, the overhanging portion 34d of the rib 34c interferes with the rib 23b constituting the guide portion 23c. Therefore, in this state, the rib 34c cannot be inserted through the guide portion 23c, and the nozzle bracket 20 cannot be assembled to the bumper bracket 30. As described above, the nozzle bracket 20 according to the present embodiment is configured so that the nozzle bracket 20 cannot be attached to the bumper bracket 30 in a direction different from the appropriate state (states 7 and 10). Therefore, it is possible to prevent the nozzle assembly 10 from being erroneously assembled.

Further, in the cleaner 1 according to the present embodiment, the engaged portions 25a and 26a are arranged outside the nozzles 13 and 13 on the plane orthogonal to the advancing and retreating directions of the piston 12, and the elastic locking pieces 37 and 38 are It is configured to engage the engaged portions 25a and 26a from the outside of the engaged portions 25a and 26a. As a result, a certain space can be provided between the nozzles 13 and 13 and the elastic locking pieces 37 and 38. Therefore, when the nozzle bracket 20 holding the nozzle assembly 10 is attached to the bumper bracket 30, it is elastically locked. It is possible to prevent the pieces 37 and 38 from colliding with the nozzles 13 and 13 so that the positions of the nozzles 13 and 13 are displaced or the nozzles 13 and 13 are damaged.

As shown in FIG. 5, the bumper bracket 30 is preferably formed vertically symmetrically. As a result, the bumper bracket 30 can be engaged with the bumper 100 by reversing the vertical direction of the bumper bracket 30 from the assembling direction as shown in FIGS. 3 and 4. Therefore, the assembling direction of the bumper bracket 30 with respect to the bumper 100 is not restricted. The bumper bracket may be formed asymmetrically in the vertical direction.

In the above embodiment, the elastic locking pieces 37, 38 of the bumper bracket 30 are configured to engage the engaged portions 25a, 26a from the outside of the engaged portions 25a, 26a of the nozzle bracket 20. , Not limited to this example. For example, protrusion-shaped engaged portions are provided on the left side surface and the right side surface of the nozzle bracket, and the elastic locking pieces of the bumper bracket are inserted into the nozzle bracket to be engaged on the left and right side surfaces of the nozzle bracket. The elastic locking piece may be engaged with the joint portion from the inside. Even with this configuration, the attachment to the bumper bracket is completed simply by the operator moving the nozzle assembly and the nozzle bracket in one direction while gripping the cylinder, so that the assembling property of the cleaner to the bumper can be improved. ..

Further, in the above embodiment, ribs 33b and 34b and ribs 33c and 34c provided with overhanging portions 33d and 34d are provided on both the upper surface 33 and the lower surface 34 of the bumper bracket 30, but this is limited to this example. I can't. For example, when only the rib 33b on the upper surface 33 is provided among the upper and lower ribs 33b and 34b, the rib 34c may be provided on the opposite side of the nozzle assembly 10 from the rib 33b. Further, when only the rib 34b on the lower surface 34 is provided among the upper and lower ribs 33b and 34b, the rib 33c may be provided on the opposite side of the nozzle assembly 10 from the rib 34b. With these configurations, it is possible to prevent the nozzle assembly 10 from being erroneously assembled.

Further, in the above embodiment, the elastic locking pieces 37 and 38 directly project rearward from the left side surface 35 and the right side surface 36 of the bumper bracket 30, but the present invention is not limited to this example. For example, one elastic locking piece protrudes rearward from the flat plate portion on the left side of the left side surface of the bumper bracket, and the other elastic locking piece protrudes rearward from the flat plate portion on the right side of the right side surface of the bumper bracket. The configuration may be adopted. In the case of this configuration, the opening of the flat plate portion formed as the internal space of the upper surface, the lower surface, the left side surface and the right side surface of the bumper bracket, and thus the opening 101 of the bumper 100 can be minimized.
