Abstract

Disclosed is a braking device in which all multiple ports (for example, input ports ( 15 c, 15 d ) and output ports ( 15 a, 15 b )) provided on a front surface portion ( 30 ) of a base ( 10 ) of a master cylinder ( 1 ), connector connection ports ( 23 a, 24 a ) of connectors ( 23, 24 ) that electrically conducts an electrical part accommodated in a housing ( 20 ), and a pipe connection port ( 3 c ) to which a hose is connected of a reservoir ( 3 ) are arranged toward front of a vehicle when a starting device (A 1 ) is assembled in the vehicle.

First claim

The invention claimed is:

1. A braking device having a reservoir that stores a brake fluid and a master cylinder that generates brake fluid pressure by an operation with a brake operator, said braking device comprising a base of the master cylinder having multiple ports formed therein including at least one inlet port into which a brake fluid is input and plural outlet ports from which the brake fluid is output, said multiple ports provided proximate one another on a single side of the base of the master cylinder, wherein the outlet ports do not function as inlet ports when the brake fluid is input into the inlet ports, and all of said multiple ports face in the same direction.

2. The braking device according to claim 1 , further comprising a housing that covers an electrical part assembled in the base, said housing provided on the base of the master cylinder, wherein:
the housing has a connector connection port through which the electrical part accommodated in the housing is electrically conducted,
the reservoir has a pipe connection port to which a pipe body is connected, and
the connector connection port and the pipe connection port face in the same direction as the multiple ports.

3. The braking device according to claim 2 , wherein all the multiple ports are arranged offset to one side, with respect to a vertical plane passing through a central axis line of the master cylinder.

4. The braking device according to claim 3 , wherein the connector connection port is arranged offset to the one side, with respect to the vertical plane passing through the central axis line of the master cylinder.

5. The braking device according to claim 2 , wherein the base has a reservoir union port that communicates with the reservoir, and all the multiple ports, the connector connection port and the pipe connection port are arranged offset to the one side with respect to a vertical plane passing through an axis line of the reservoir union port.

6. A braking device having a reservoir that stores a brake fluid and a master cylinder that generates brake fluid pressure by an operation with a brake operator, said braking device comprising:
a base of the master cylinder having multiple ports formed therein including at least one inlet port into which a brake fluid is input and a plurality of outlet ports from which the brake fluid is output, said multiple ports provided proximate one another on a single side of the base of the master cylinder,
and a housing that covers an electrical part assembled in the base, said housing provided on the base of the master cylinder, the housing having a connector connection port through which the electrical part accommodated in the housing is electrically connected,
wherein the outlet ports do not function as inlet ports when the brake fluid is input into the inlet ports, and all of said multiple ports and the connector connection port all face in the same direction.

7. The braking device according to claim 6 , wherein the reservoir has a pipe connection port to which a pipe body is connected, and the pipe connection port faces in the same direction as the multiple ports and the connector connection port.

8. The braking device according to claim 6 , wherein all the multiple ports are arranged offset to one side, with respect to a vertical plane passing through a central axis line of the master cylinder.

9. The braking device according to claim 6 , wherein the connector connection port is arranged offset to the one side, with respect to the vertical plane passing through the central axis line of the master cylinder.

10. The braking device according to claim 6 , wherein the base has a reservoir union port that communicates with the reservoir, and all the multiple ports, the connector connection port and the pipe connection port are arranged offset to the one side with respect to a vertical plane passing through an axis line of the reservoir union port.
