A structure to fix a hydraulic line according to the present invention includes: a structure box accommodating an oil pressure controller connected to a hydraulic pump; and a sealing unit which connects multiple hydraulic tubes of the hydraulic line connected from the oil pressure controller to an actuator outside the structure box as sealing the structure box, and is configured to prevent oil leakage of a connection portion of the hydraulic tube. The structure of the present invention can prevent inflow of external foreign substances and oil leakage, by constituting the sealing unit which is configured to connect the multiple hydraulic tubes of the hydraulic line connected from the oil pressure controller to the actuator outside the structure box as sealing the structure box and prevents oil leakage of the connection portion of the hydraulic tube. Particularly, the structure of the present invention can prevent inflow of the external foreign substances into the structure box by facilitating interconnection between an inner hydraulic tube and an outer hydraulic tube without a large passing space as to the hydraulic tube additionally on the cover, by constituting the cover which is inserted with a connector and has a connection hole maintaining airtightness around the connector. Also, an airtight interconnection structure not causing oil leakage at the connection portion can be obtained by simplifying connection assembly, according as an arrangement shape structure of the inner hydraulic tube and the outer hydraulic tube is not complicated, since the inner hydraulic tube and the outer hydraulic tube are connected by the connector. |
