PROBLEM TO BE SOLVED: To provide a slide member which can prevent foreign substances on a sliding surface from being discharged to the outside and does not degrade performance, appearance and the like of an integrated device, and to provide a timepiece having the slide member.SOLUTION: A slide member 10 includes: a sliding member 20 with a rotational shaft 22; and a sliding member 30 with a hole 32 into which the rotational shaft 22 is inserted. The sliding member 20 and the sliding member 30 are combined to be relatively slidable. A groove part 21 is formed on a sliding surface 23 of the sliding member 20, and a groove part 31 is formed on a sliding surface 33 of the sliding member 30. The groove part 21 and the groove part 31 overlap with each other at least partially and intermittently in association with sliding of the sliding members 20 and 30, and store such foreign substances as dust entering when the slide component 10 is assembled or abrasion powder generated on the sliding members 23 and 33 in association with sliding of the sliding members 20 and 30.SELECTED DRAWING: Figure 1 【課題】摺動面上にある異物が外部へ排出されるのを防ぎ、組み込まれる装置の性能や美観等を損なうことのない摺動部品及びそれを備えた時計を提供すること。【解決手段】摺動部品１０は、回転軸２２を有する摺動部材２０と、回転軸２２が挿通される穴３２を有する摺動部材３０とを有し、摺動部材２０と摺動部材３０が相対的に摺動可能に組み合わされて構成されている。摺動部材２０の摺動面２３には溝部２１が形成されており、摺動部材３０の摺動面３３には溝部３１が形成されている。そして、溝部２１及び３１は、摺動部材２０，３０の摺動に伴い、その少なくとも一部が断続的に重なるように形成されており、摺動部品１０を組み立てる際に入り込んだ塵埃や、摺動部材２０，３０の摺動に伴って摺動面２３，３３上に生じた磨耗粉などの異物が収納されるようになっている。【選択図】図１
