For example, the body 71 and the cover 75 are integrally molded using a synthetic resin. The cover 75 contains a synthetic resin. The body 71 contains a synthetic resin. The cover 75 is formed in a rod shape protruding from an end surface of the main body 71 on the side opposite to the hydraulic pressure chamber 201 (hydraulic pressure chamber 401). For example, the cover 75 is cylindrical. The cross-sectional area of the cover 75 in a cross section orthogonal to the axial direction of the body 71 is larger than the cross-sectional area of the flow path 73 in the cross section. When viewed from the axial direction of the main body 71, the cover 75 and the entire surface of the flow path 73 overlap. The shape of the cover 75 is not limited to a cylindrical shape.
蓋75設置為能至少局部地從本體71脫離。蓋75係以藉由蓋75向與從液壓室201(液壓室401)離開之方向不同之方向被推壓而使流路73之與液壓室201(液壓室401)相反之側之端部開口之方式構成。當蓋75在本體71之徑向(相對於軸向正交之方向)被推壓，則蓋75塑性變形。如圖8所示，蓋75之本體71側之端部從本體71脫離。藉此，流路73之與液壓室201(液壓室401)相反之側之端部開口。The cover 75 is provided to be detachable from the body 71 at least in part. The cover 75 is pushed by the cover 75 in a direction different from the direction away from the hydraulic pressure chamber 201 (hydraulic pressure chamber 401) to open the end of the flow path 73 on the side opposite to the hydraulic pressure chamber 201 (hydraulic pressure chamber 401).

Thereby, the flow path 73 of the plug 7 is opened. Thereafter, the plug 7 is pulled out from the first hydraulic device 2. Since the flow path 73 is opened, the splash of oil when the plug 7 is pulled out is suppressed. Thereafter, one end of the hose 6 is inserted into the hydraulic chamber 201 of the first hydraulic device 2. The membrane 66 is broken by the needle 25, so that the piston chamber 202 of the first hydraulic device 2 and the flow path 611 of the hose 6 are communicated. Thereafter, the threaded sleeve joint 26 is rotated to deform the bushing 27 and bite into the hose body 61. Thereby, the hose 6 is fixed to the first hydraulic device 2.
軟管6與第2液壓裝置4連接時，首先，使第2液壓裝置4之插塞7之蓋75脫離。藉此，插塞7之流路73開口。其後，插塞7從第2液壓裝置4被拔出。由於流路73開口，故拔出插塞7時之油之飛濺得到了抑制。其後，軟管6之另一端被***至第2液壓裝置4之液壓室401。藉由針45弄破膜66，從而使第2液壓裝置4之活塞室402與軟管6之流路611連通。其後，藉由螺紋套管接頭46被旋轉，使襯套47變形並咬入至軟管本體61。藉此，軟管6被固定在第2液壓裝置4。When the hose 6 is connected to the second hydraulic device 4, first, the cap 75 of the plug 7 of the second hydraulic device 4 is detached. Thereby, the flow path 73 of the plug 7 is opened. Thereafter, the plug 7 is removed from the second hydraulic device 4. Since the flow path 73 is opened, the splash of oil when the plug 7 is pulled out is suppressed. Thereafter, the other end of the hose 6 is inserted into the hydraulic chamber 401 of the second hydraulic device 4. The membrane 66 is broken by the needle 45, so that the piston chamber 402 of the second hydraulic device 4 and the flow path 611 of the hose 6 are communicated. Thereafter, the threaded sleeve joint 46 is rotated to deform the bushing 47 and bite into the hose body 61. Thereby, the hose 6 is fixed to the second hydraulic device 4.
圖9係搬送時之實施形態之刹車系統之模式圖。圖10係連接於液壓裝置之前之實施形態之軟管之立體圖。如圖9所示，搬送軟管6時，軟管6例如以與第2液壓裝置4連接之狀態下被放入箱100。箱100具備支持構件101。軟管6如圖9所示以軟管本體61不纏繞於支持構件101之全周之方式垂吊於支持構件101。藉此，軟管6不易有所謂之纏繞傾向。FIG. 9 is a schematic diagram of a braking system according to an embodiment during transportation. FIG. 10 is a perspective view of the hose in the embodiment before being connected to the hydraulic device. As shown in FIG. 9, when the hose 6 is transported, the hose 6 is put into the tank 100 with the second hydraulic device 4 connected, for example. The box 100 includes a supporting member 101. As shown in FIG. 9, the hose 6 is hung from the support member 101 so that the hose body 61 is not wound around the entire circumference of the support member 101. This makes it difficult for the hose 6 to have a so-called winding tendency.
如圖10所示，在與第1液壓裝置2及第2液壓裝置4連接之前，軟管6具備封蓋68、及繩69。封蓋68保護軟管6之端部。將軟管6安裝於腳踏車之車架時，有時將軟管6穿過車架之內部。於該情形時，為了使軟管6穿過而預先設置於車架之構件與安裝於封蓋68之孔681之繩69連接。並且，拉拽繩69，使封蓋68進入車架之內部。於本實施形態中，封蓋68之表面被實施了低摩擦塗佈。藉此，車架內部之軟管6之移動變得順暢。As shown in FIG. 10, before being connected to the first hydraulic device 2 and the second hydraulic device 4, the hose 6 includes a cap 68 and a rope 69. The cover 68 protects the end of the hose 6. When attaching the hose 6 to the frame of the bicycle, the hose 6 may be passed through the inside of the frame. In this case, a member provided in the frame in advance to allow the hose 6 to pass therethrough is connected to the rope 69 attached to the hole 681 of the cover 68. Then, the rope 69 is pulled so that the cover 68 enters the inside of the frame. In this embodiment, the surface of the cover 68 is coated with low friction. Thereby, the movement of the hose 6 inside the frame becomes smooth.
(變化例)
圖11係變化例之插塞之周邊之放大圖。如圖11所示，變化例之插塞7A具備與上述之蓋75不同之蓋75A。再者，對於與上述之實施形態相同的構成，附有相同符號並省略說明。(Modification)
FIG. 11 is an enlarged view of the periphery of the plug according to the modification. As shown in FIG. 11, the plug 7A of the modified example includes a cover 75A different from the cover 75 described above. In addition, the same configurations as those of the above-mentioned embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

For example, the body 71 and the cover 75A are integrally molded using a synthetic resin. The cover 75A contains a synthetic resin. The end face of the cover 75A and the main body 71 opposite to the hydraulic pressure chamber 201 (hydraulic pressure chamber 401) is integrated. That is, the cover 75A does not protrude from the end surface of the body 71, but is formed as a part of the disc-shaped end surface of the body 71.
蓋75A設置為能至少局部地從本體71脫離。蓋75A係以藉由蓋75A向與從液壓室201(液壓室401)離開之方向不同之方向被推壓而使流路73之與液壓室201(液壓室401)相反之側之端部開口之方式構成。當蓋75A向朝液壓室201(液壓室401)之方向被推壓，則蓋75A塑性變形。具體而言，蓋75A塑性變形，進入流路73之內部。藉此，流路73之與液壓室201(液壓室401)相反之側之端部開口。例如，為了使蓋75A變形會使用前端尖突之工具等。The cover 75A is provided to be able to be detached from the body 71 at least partially. The cover 75A is pushed by the cover 75A in a direction different from the direction away from the hydraulic pressure chamber 201 (hydraulic pressure chamber 401) to open the end of the flow path 73 on the side opposite to the hydraulic pressure chamber 201 (hydraulic pressure chamber 401) Way of composition. When the cover 75A is pushed toward the hydraulic pressure chamber 201 (hydraulic pressure chamber 401), the cover 75A is plastically deformed. Specifically, the cover 75A is plastically deformed and enters the inside of the flow path 73. Thereby, the end of the flow path 73 on the side opposite to the hydraulic pressure chamber 201 (hydraulic pressure chamber 401) is opened. For example, in order to deform the cover 75A, a tip or the like is used.
