Claims (11)

  1. A disc brake (10) comprising: a friction pad (24, 25) that is provided at a position next to a disc rotor (11) in a disc axial direction and provided to be able to move in the disc axial direction; and a carrier (21) that has an inner circumferential surface (21b) supporting the friction pad (24, 25) and formed along an outer circumferential edge of the disc rotor (11) and a filter portion (55, 56) provided on the inner circumferential surface (21b) in a manner of facing the outer circumferential edge of the disc rotor (11), and characterized in that the filter portion (55, 56) is constituted of a dust collection portion (191) made up of an elastic body and an attachment plate (192) made up of an elastic body for attaching the dust collection portion (191) to a carrier main body (29) of the carrier (21), and the attachment plate (192) presses the dust collection portion (191) in a manner of coming into surface contact with the inner circumferential surface (21b) of the carrier main body (29).
  2. The disc brake (10) according to claim 1, wherein the attachment plate (192) is provided with an attachment portion (212, 213) for attachment with respect to the carrier main body (29), and the attachment plate (192) includes a position setting plate portion (193) which positionally sets the dust collection portion (191) and is unlikely to be detached from the carrier main body (29) by tip portions of the attachment portion (212, 213) provided on the position setting plate portion (193) extending in a state of obliquely such that the tip portions are separated from each other to the inward side in the disc radial direction and enter the engagement holes (171, 181) formed in the carrier main body (29), and a clip-type plate portion (194) which supports the dust collection portion (191) and is able to be detached from the carrier main body (29).
  3. The disc brake (10) according to claim 2, wherein the position setting plate portion (193) is provided in a direction of a disc center axis with respect to the dust collection portion (191).
  4. The disc brake (10) according to claim 2, wherein the clip-type plate portion (194) is provided next to the dust collection portion (191) in a disc circumferential direction.
  5. The disc brake (10) according to claim 1, wherein the attachment plate (192) is provided with a hole.
  6. The disc brake (10) according to claim 1, wherein the filter portion (55, 56) is provided on a disc exit side of the carrier (21).
  7. The disc brake (10) according to claim 1, wherein the dust collection portion (191) is provided on both sides a disc entrance side and a disc exit side of the carrier (21).
  8. The disc brake (10) according to claim 1, wherein the carrier (21) is provided with a hole at a position of the filter portion (55, 56).
  9. The disc brake (10) according to claim 1, wherein the filter portion (55, 56) is made up of a first filter portion (56) and a second filter portion (55).
  10. The disc brake (10) according to claim 9, wherein the first filter portion (56) is provided on a disc exit side of the carrier (21).
  11. The disc brake (10) according to claim 1, wherein the filter portion (55, 56) is continuously provided from a disc entrance side to a disc exit side of the carrier (21).

Description

[Technical Field] The present invention relates to a disc brake and a carrier. Priority is claimed on Japanese Patent Application No. 2021-067812, filed April 13, 2021. [Background Art] Some disc brakes have a separate-type brake dust collector installed next to a brake caliper (for example, refer to US 2020/0271176 A1). US 2007/000740 A1 is related to a disc brake comprising friction pads provided at a position adjacent a disc rotor in a manner movable in the disc axial direction. The disc brake further has a carrier having an inner circumferential surface supporting the friction pad and formed along an outer circumferential edge of the disc rotor as well as a filter portion provided on the inner circumferential surface in a manner facing the outer circumferential edge of the disc rotor. Similar disc brakes are derivable from DE 10 2016 108 793 A1 and DE 103 36 984 A1. [Summary of Invention] [Technical Problem] There is a demand for efficient collection of brake dust. An object of the present invention is to provide a disc brake and a carrier in which brake dust can be efficiently collected. [Solution to Problem] In order to achieve the foregoing object, a disc brake of the present invention includes the features of claim 1. An aspect according to a carrier of the present disclosure includes an inner circumferential surface that supports a friction pad and is formed along an outer circumferential edge of a disc rotor, and a filter portion that is provided on the inner circumferential surface in a manner of facing the outer circumferential edge of the disc rotor. [Advantageous Effects of Invention] According to the present invention, brake dust can be efficiently collected.
