As shown in FIG. In the present embodiment, the inner diameter D of the insertion hole 32 a of the C-shaped ring 32 is configured to be smaller than the diameter of the shaft 20. Further, the outer diameter E of the C-shaped ring 32 is configured to be larger than the inner diameter F of the insertion hole 31 of the cylindrical support portion 30 and smaller than the outer diameter H of the cylindrical support portion 30. Here, the “neighboring position” means a distance of about 3 cm from the insertion side end S. In addition, as the configuration in which the cylindrical support portion 30 includes the C-shaped ring 32, any configuration can be used as long as the C-shaped ring 32 does not move in the axial direction when the cylindrical support portion 30 is inserted into and removed from the shaft 20. There may be.

  Furthermore, in this embodiment, as shown in FIG. 1 and FIG. 2, the fitting concave portion that fits the fitting convex portion 21 of the shaft 20 on the inner peripheral surface N of the insertion side end portion S of the cylindrical support portion 30. 33 is provided with a pair.

  Next, with reference to FIG. 3, FIG. 4, the case where the roller implement 1 which consists of such a structure is used is demonstrated.

First, the case where the roller tool 1 is used in a state where the roll body 40 is rotatable will be described.
In this case, as shown in FIGS. 3A and 4A, the cylindrical support portion 30 is inserted into the shaft 20 at the tip position (position on the tip side) with respect to the fitting convex portion 21 in the shaft 20. . In this case, it is necessary to insert the cylindrical support portion 30 through the shaft 20 to a position where the cylindrical support portion 30 is supported by the shaft 20 by at least the restoring force of the C-shaped ring 32.
Thereby, the cylindrical support part 30 provided with the roll body 40 is rotatably supported by the shaft 20 via the C-shaped ring 32.
Such a use state is useful when, for example, dust is cleaned while the roll body 40 is rotated.
In the present embodiment, a C-shaped ring 32 is provided in the vicinity of the insertion side end S of the cylindrical support 30. Therefore, if it is the structure which inserts the cylindrical support part 30 in the shaft 20 in the front-end | tip position rather than the convex part 21 for fitting, depending on the use environment and use of the roller tool 1, the length which inserts the cylindrical support part 30 with respect to the shaft 20 Can be appropriately changed.

Next, the case where the roller tool 1 is used in a state where the rotation of the roll body 40 is suppressed will be described.
In this case, as shown in FIGS. 3B and 4B, the cylindrical support portion 30 is inserted through the shaft 20 at a position where the fitting convex portion 21 and the fitting concave portion 33 are fitted.
Thereby, the cylindrical support part 30 provided with the roll body 40 is supported on the shaft 20 through the C-shaped ring 32 in a non-rotatable state.
Such a use state is useful, for example, when the roller tool 1 is used for polishing a paint.

  The roller device 1 according to the embodiment of the present invention having such a configuration has the following effects.

  The shaft 20 is provided with a fitting convex portion 21, and the cylindrical support portion 30 is provided with a fitting concave portion 33 for fitting with the fitting convex portion 21, and the fitting convex portion 21 and the fitting concave portion 33 are not fitted. The roll body 40 can be used in a state where the roll body 40 can be rotated with one roller device 1 by using a configuration in which both the use in the state and the use in the fitted state are possible. Use in a state where the rotation of 40 is suppressed can be properly used depending on the purpose. Therefore, it can be set as the roller tool 1 which can be used for many purposes.

  Further, by providing a pair of the fitting convex portion 21 and the fitting concave portion 33 in the radial direction, the fitting state between the fitting convex portion 21 and the fitting concave portion 33 can be more reliably maintained. . Therefore, the rotation of the roll body 40 can be more reliably suppressed via the cylindrical support portion 30. Therefore, the roller tool 1 with good workability can be obtained.

  In addition, by adopting a configuration in which the gripping part 10, the shaft 20, and the cylindrical support part 30 are arranged coaxially, even if the place where the roller tool 1 performs work is a place where the depth or the frontage is narrow, The roll body 40 can be easily arranged at the work position. Therefore, it can be set as the roller tool 1 with good workability.

  A C-shaped ring 32 having an inner diameter D smaller than the diameter of the shaft 20, an outer diameter E larger than an inner diameter F of the insertion hole of the cylindrical support portion 30 and smaller than an outer diameter H of the cylindrical support portion 30 is The cylindrical support part 30 is configured so that the cylindrical support part 30 is supported by the shaft 20 by the restoring force when the shaft 20 is inserted through the C-shaped ring 32 while being disposed inside the cylindrical support part 30. Can be more reliably supported by the shaft 20. Therefore, it is possible to effectively prevent the cylindrical support portion 30 from falling off the shaft 20 during use.

  Further, by providing the C-shaped ring 32 in the vicinity of the insertion-side end portion S, the entire length of the roller device 1 can be easily increased only by changing the insertion length (depth) of the cylindrical support portion 30 with respect to the shaft 20. It can be set as the roller tool 1 which can be changed into.

  In the present embodiment, the C-shaped ring 32 is included in the cylindrical support portion 30. However, the present invention is not necessarily limited to such a configuration. In other words, when the cylindrical insertion portion 30 is inserted into the shaft 20, the cylindrical support portion is configured so that the cylindrical insertion portion 30 can be supported by the shaft 20 via the restoring force of the C-shaped ring 32. The arrangement configuration of the C-shaped ring 32 with respect to 30 may be any configuration.

  Moreover, in this embodiment, although the roll body 40 was made to adhere to the outer periphery of the cylindrical support part 30 via an adhesive, it is not necessarily limited to such a configuration. For example, it is good also as a structure which attaches the roll body 40 to the cylindrical support part 30 so that attachment or detachment is possible. By setting it as such a structure, it can be set as the roller tool 1 which can replace | exchange the roll body 40 and the cylindrical support part 30 separately.

  In the present embodiment, the shaft 20 is fixedly attached to the grip portion 10, but is not necessarily limited to such a configuration. For example, the gripping unit 10 may be provided with an electric mechanism, and the shaft 20 may be attached to the gripping unit 10 in a state where the shaft 20 can be automatically rotated. With such a configuration, even in a situation where the place where the roller tool 1 is used is narrow and the roller body 1 cannot be moved by moving the roller tool 1 left and right, the roll body 40 can be freely rotated to work. Can be performed. Therefore, it can be set as the roller tool 1 excellent in workability | operativity. In addition, when rotating the shaft 20 automatically, it is necessary to make the fitting convex part 21 and the recessed part 33 for fitting fit.

  Since the roller device of the present invention is useful during operations such as cleaning and application of paint, it is useful in the field of cleaning tools and painting tools, and has great industrial applicability.
