A memory card connector has a sliding member and a sliding pin for coupling the insertion and rejection of the memory card. The sliding member can be stayed at the position of insertion or rejection of the memory card. A retaining sheet is formed on the side of the sliding member. The end of the retaining sheet is stamped into a dimple. A retaining portion is formed on the housing of the memory card connector corresponding to the position of the dimple. The dimple can be pushed into the retaining portion when the memory card is rejected to the rejection position.
