A receiving opening (11) is set on one side of a housing (1) formed as a main structure. A W-type contacting surface (12) is formed by contacting surfaces (121,122) on other side of housing opposite the receiving opening. Position holes (123) are set on the contacting surfaces, and position columns (124) are set at both sides inside the housing in the direction of the receiving opening. |
