Title:
燃料圧力センサの接続構造
Document Type and Number:
Japanese Patent JP7337725
Kind Code:
B2
Abstract:
To provide a connection structure for a fuel pressure sensor that can prevents relative rotation between an abutting surface of a fuel rail and a sealing surface of a fuel pressure sensor, so as to suppress a deterioration in a sealing performance. A connection structure (1) for a fuel pressure sensor that connects a fuel pressure sensor (106) for detecting a pressure of a fuel to a fuel rail (103) in which the fuel to be supplied to an internal-combustion engine flows, includes a tubular attachment boss (10) that is formed in the fuel rail (103) and includes a male screw portion (13) and an abutting surface (14), an attachment portion (20) that is provided in a sensor body (106a) of the fuel pressure sensor (106), and includes a contact surface (22a) that abuts to the abutting surface (14) and a bearing surface (22b) provided behind the contact surface (22a), and a nut (30) including a female screw portion (33) that is screwed on the male screw portion (13) and a pressing portion (34) that presses the bearing surface (22b) to the abutting surface (14) by screwing the female screw portion (33) on the male screw portion (13).
