The contact of the elastic piece 101 is stopped by the contact. For this reason, the contact part 102 of the elastic piece 101 and the upper surface of the elastic piece receiving part 165 will be in the state connected with sufficient contact pressure.
In a state where the fixing piece 111 is bolted to the attached portion 162, the elastic piece 101 is elastically deformed, so that the shield shell 30 is inclined obliquely upward due to the electric wire W being shaken upward or the like. In this case, the amount of bending of the elastic piece 101 is slightly reduced, but the contact portion 102 remains pressed against the elastic piece receiving portion 165, and the shielding performance can be maintained.
A pair of left and right reinforcing ribs 113 are formed on the upper surface of the upper member 110. The reinforcing rib 113 is arranged at a position where the fixed piece 111 and the shell main body 115 are connected. The reinforcing rib 113 is formed in a substantially triangular shape that becomes wider as it approaches the fixed piece 111 from the shell body 115. For this reason, even if the electric wire W is shaken in the vertical direction, the fixed piece 111 is not easily deformed with respect to the shell body 115.
Further, as shown in FIG. 5, a guide groove 114 is formed in the shell main body 115 so as to open forward. The shell fixing portion 26 can enter the guide groove 114. That is, when the housing 20 and the shield shell 30 are assembled in the front-rear direction, the shell fixing portion 26 is guided through the guide groove 114, so that the shield shell 30 and the housing 20 can be easily assembled in a normal posture. become.
