  The attachment portion 34 includes a connector portion 341 that fits with the cleaning portion side connector portion 201 of the main body portion 20. When the attachment portion 34 is attached to the main body portion 20, its longitudinal direction is the extending direction (in other words, the main body portion 20. It is fixed in a state along the longitudinal direction.

  The application unit 40 is a member for applying lubricating oil on the hanger rail 3. The application unit 40 includes an impregnation unit 42, an attachment unit 44, a communication pin 46 that allows the impregnation unit 42 and the attachment unit 44 to communicate with each other, and the attachment unit 44. And a fixing portion 47 for stopping the rotation operation.

  The impregnation part 42 is a part having a J shape along the outer shape (substantially convex shape) of the upper part of the hanger rail 3. Moreover, the impregnation part 42 has a flexible member impregnated with a sufficient amount of lubricating oil. The impregnation part 42 has a flexible member having a sufficiently high oil-absorbing property, and can be configured using, for example, a non-woven member such as felt. Here, when the fixing portion 47 is loosened, the impregnation portion 42 can be rotated about the communication pin 46 as a rotation axis. And the angle with respect to the longitudinal direction of the attachment part 44 (longitudinal direction of the main-body part 20) can be freely adjusted about the impregnation part 42 by rotating the impregnation part 42. FIG. Then, when the fixing portion 47 is tightened at a desired position, the impregnation portion 42 cannot be rotated about the communication pin 46 as a rotation shaft. As a result, the impregnation portion 42 is moved in the longitudinal direction of the attachment portion 44 (of the main body portion 20). The angle with respect to the longitudinal direction) can be fixed.

  The attachment portion 44 includes a connector portion 442 that fits with the application portion side connector portion 202 of the main body portion 20, and when attached to the main body portion 20, its longitudinal direction is the extending direction (in other words, the main body portion 20. It is fixed in a state along the longitudinal direction.
