To provide a belt capable of achieving excellent durability by suppressing bending at a joint.SOLUTION: According to one embodiment, a belt is provided. A belt 10 has a strip-like belt base material 1 having a first end portion 1a and a second end portion 1b. The first end portion 1a and the second end portion 1b are abutted against each other and joined to form a joint portion 1c so that the belt base material 1 forms an annular structure. The first end portion 1a includes a plurality of first protrusions 31a and a plurality of first recesses 31b. The second end portion includes a plurality of second protrusions 32a and a plurality of second recesses 32b. Each of the plurality of first protrusions 31a is fitted with each of the plurality of second recesses 32b. Each of the plurality of second protrusions 32a is fitted with each of the plurality of first recesses 31b. The belt 10 further includes a backing 2 and a first layer 3.SELECTED DRAWING: Figure 1 【課題】接合部での折れ曲がりを抑制することで、優れた耐久性を達成可能なベルトを提供すること。【解決手段】一実施形態によれば、ベルトが提供される。ベルト１０は、帯状を有すると共に第１端部１ａ及び第２端部１ｂを有するベルト基材１を備える。第１端部１ａ及び第２端部１ｂは、ベルト基材１が環状構造をなすように互いに突き合わせて接合して接合部１ｃを構成している。第１端部１ａは、複数の第１凸部３１ａ及び複数の第１凹部３１ｂを備える。第２端部は、複数の第２凸部３２ａ及び複数の第２凹部３２ｂを備える。複数の第１凸部３１ａのそれぞれは、複数の第２凹部３２ｂのそれぞれと嵌合している。複数の第２凸部３２ａのそれぞれは、複数の第１凹部３１ｂのそれぞれと嵌合している。ベルト１０は、裏材２と、第１層３とを更に備える。【選択図】図１
