CYLINDER DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/147127
Kind Code:
A1
Abstract:
A cylinder device (A2), which is provided with: a substrate (11) having a cylinder hole (11a) and a reservoir union port (17a); a piston (12) which is inserted into the cylinder hole (11a); a regulation member (19) which regulates the rearward limit of the piston (12); a reservoir (40) having a liquid supply part (41); and a seal member (44) which is for the reservoir and which is externally fitted to the liquid supply part (41). Therein: the substrate (11) comprises a mounting hole (11h) and a first communication hole (17c) which open to the reservoir union port (17a) and the cylinder hole (11a); the regulation member (19) is inserted into the mounting hole (11h); and the liquid supply part (41) has a cut-out section (41d) and a tip section (41e) arranged so as to face the regulation member (19). This structure enables the number of components to be reduced, reduces the size of the substrate (11), and also prevents air from collecting inside the reservoir union port (17a).
