In addition, back and forth slot part 11C is formed with rake 15 and moving direction restriction end difference 16, so that when the sliding part 7b of pilot pin carries out toward action, can not move and when carrying out the double action action, can not yearn for road guiding groove section 11A from moving to return road guiding groove section 11B toward road guiding groove section 11A from return road guiding groove section 11B.
On the other hand, formed constituting on the protective cover 2b of housing 2, the sliding part 7b of restriction pilot pin moves with spring leaf 20 (abbreviation " reed ") at the banking pin that begins the action when mobile toward the guiding groove section 11A of road in from releasing stop position a.
With regard to this reed 20, its cardinal extremity 20a is configured to make the sidewall 21 of protective cover 2a to prolong, and by being U font and the 20b of spring portion that turns back and form one-sided formula, is approximate right angle and forming as one with the 20c of margining tablet portion with its front end bending with reed 20 bendings.
The 20c of this margining tablet portion be positioned at the both sides of releasing stop position a toward the road, two pin gathering sill 11A, the 11B in return road, dispose in mode only across the opening portion of past road guiding groove section 11A.And if the sliding part 7b of pilot pin is beginning to move in the guiding groove section 11A of road from releasing stop position a, then it can be met the 20c of margining tablet portion and apply moving resistance.
The value of this moving resistance is redefined for than little to the forward operation power of slide block 1 via card A when the push operation, and bigger than the to a certain degree following external force that applies because of common vibration.
Prevent returning in mechanism's push-push connector at the band of this structure, make slide block 1 to releasing the direction action, when the sliding part 7b of pilot pin pushes back out stop position a at return road pin gathering sill 11B internal return, though be not subjected to being used to cross moving direction restriction end difference 16 resistance in addition, but because only when releasing stop position a to the direction of propulsion side shifting, be restricted pin and move the resistance of using spring leaf 20, thereby can resist the external force of the slide block direction of propulsion that causes because of common vibration, thereby can prevent that casual card from advancing action with this reed 20.
On the other hand, in common push operation,, reed 20 flexibly is out of shape from going up to disengaging configuration toward road pin gathering sill 11A, thereby can cause big influence push operation because operating personnel apply bigger operating physical force.
In addition, in the above-described embodiment, though in road guiding groove section 11A and return road guiding groove section 11B, be provided with both shared reciprocal slot part 11C, but in addition, as shown in Figure 6, also can not be provided with toward the common sparing of road guiding groove section 11A and return road guiding groove section 11B, and make whole position be positioned at the position of dividing right and left.
