To provide a valve timing control device of an internal combustion engine which enables improvement in work efficiency of assembly of a power supply brush etc. to a brush holder.SOLUTION: A brush holder 29 includes: a guide part 33 folded into a square cylinder shape and having a first side wall part 35, a second side wall part 36, a third side wall part 37, and a fourth side wall part 38; and a lid part 34 provided integrally with one end part of the first side wall part 35. The guide part has a housing hole 33a that houses and holds a power supply brush 40 and a compression coil spring 41 therein from a first opening 33b. Meanwhile, the lid part 34 has: a lid body 34a which covers the first opening 33b; and a connection part 34b which connects the lid body with one end edge of the frist side wall part. The connection part is formed having a width narrower than the lid body so as to reduce rigidity, and serves as a bending point.SELECTED DRAWING: Figure 4 【課題】ブラシホルダに対する給電用ブラシなどの組付作業能率の向上を図り得る内燃機関のバルブタイミング制御装置を提供する。【解決手段】ブラシホルダ２９は、四角筒状に折曲形成されて、第１側壁部３５と、第２側壁部３６と、第３側壁部３７と、第４側壁部３８と、を有するガイド部３３と、第１側壁部３５の一端部に一体に設けられた蓋部３４とを備えている。ガイド部は、第１開口部３３ｂから内部に給電用ブラシ４０と圧縮コイルばね４１を収容保持する収容孔３３ａを有する一方、蓋部３４は、第１開口部３３ｂを覆うと、該蓋本体３４ａと、第１側壁部の一端縁とを連結する連結部３４ｂと、を有している。この連結部は、剛性を低くするために蓋本体よりも狭幅に形成されて、ここを折り曲げ点としている。【選択図】図４
