PROBLEM TO BE SOLVED: To provide a vehicular brake device in which bleeding can be performed by brake operation.SOLUTION: The vehicular brake device comprises: a liquid pressure chamber formation part having first bottomed cylindrical parts 14b, 14c disposed in a master cylinder 11, linked to a master piston 14 or moving as part of the master piston 14, and having a bottom surface on their front parts respectively, and having second bottomed cylindrical parts 12a, 38a whose front end parts are disposed in the first bottomed cylindrical parts, and whose bottom surfaces are formed on the front end parts; and a reservoir 19 which is coupled to insides of the second bottomed cylindrical parts via a first channel being blocked and communicated according to operation of a brake operation member 71. The second bottomed cylindrical parts have plural penetration paths 12z for communicating inside and outside of the second bottomed cylindrical parts on their peripheral wall parts, and the penetration paths 12z extend in a direction crossing a radial direction of the second bottomed cylindrical parts in an axial orthogonal cross section of the second bottomed cylindrical parts. |
