Elevating mechanism and socket for electrical component

An elevating mechanism comprising:

• an elevating part supported by a body part such that the elevating part can be moved up and down;
• and a pressing part supported by the body part and moving down the elevating part,
• wherein the pressing part includes a first cam rotatably supported by the body part, and a second cam supported by the first cam and capable of being rotated and moved in a radial direction of the rotation,
• the elevating part includes a cam locking part provided on a rotational orbit of the second cam,
• a shape of a tip of the second cam is formed such that the tip of the second cam passes over the cam locking part when the elevating part is moved down by making the tip of the second cam abut against the elevating part and rotate, and the tip of the second cam is locked by the cam locking part so as to prevent the rotation when an attempt is made to perform the rotation in the opposite direction, and
• the rotation in the opposite direction is enabled by moving the second cam in the radial direction of the rotation with respect to the first cam, so as to release a locked state between the second cam and the cam locking part.
