Slider and slide fastener with same

1. A slider comprising:

a slider body comprising an upper vane, a lower vane, and a guide post connecting the upper vane and the lower vane; and

a pull tab connected to the slider body, wherein

the upper vane is provided with a pair of lateral walls projecting from an upper surface of the upper vane in a thickness direction of the slider body in which the upper vane and the lower vane are opposed,

a connection bearing for a connecting pin supported by the pair of lateral walls to be inserted is provided to the pull tab,

the upper vane is provided with a recess dented toward the lower vane in the thickness direction of the slider body with respect to the upper surface, or a hole penetrating from the upper surface through the upper vane, and

the connection bearing is located in the recess or the hole between the pair of lateral walls,

a shaft hole for the connecting pin is provided in each lateral wall, and

at least a part of the shaft hole is located below a portion of the upper surface of the upper vane, wherein the portion of the upper surface of the upper vane is a surface along a top surface of the upper vane close to a posterior opening with respect to the recess or the hole.

2. The slider according to claim 1 , wherein the recess is provided with a recess bottom surface, thicknesses from the recess bottom surface to a guiding groove defined between the upper vane and the lower vane being smaller than a thickness from the upper surface of the upper vane to the guiding groove.

3. The slider according to claim 1 , further comprising:

an elastic lock member configured to elastically bias the pull tab in a rotation direction around the connecting pin toward a lock position at which the pull tab is laid along the upper surface of the upper vane, wherein

the recess comprises a pair of shoulders located on both sides of the slider body in a width direction orthogonal to the thickness direction, and a middle recess located between the pair of shoulders, the middle recess being dented with respect to a recess bottom surface of the pair of shoulders, the recess bottom surface defining a first recess bottom surface and a second recess bottom surface defined by the pair of shoulders and the middle recess, respectively,

the elastic lock member is disposed in the middle recess in a manner to be projectable into and retractable from a guiding groove defined between the upper vane and the lower vane, and

the first recess bottom surface of the pair of shoulders is located at a lower position closer to the lower vane with respect to the upper surface of the upper vane.

4. The slider according to claim 3 , wherein the connection bearing comprises a pair of side bearings disposed above the pair of shoulders and a cam disposed above the middle recess,

the elastic lock member is disposed in a manner capable of elastically biasing the cam toward the lock position,

the connecting pin penetrates through the pair of side bearings and the cam, and

a thickness of the connection bearing at each of the pair of side bearings between the first recess bottom surface of the pair of shoulders and an outer circumferential surface of the connecting pin is smaller than a thickness of the connection bearing at the cam between the second recess bottom surface of the middle recess and the outer circumferential surface of the connecting pin.

5. The slider according to claim 3 , wherein a maximum height of the pair of the lateral walls from the first recess bottom surface at the pair of shoulders in the thickness direction of the slider body is larger than a maximum diameter of the connection bearing.

6. The slider according to claim 3 , wherein the pair of shoulders comprise the first recess bottom surface and a pair of recess side surfaces located on both ends of the first recess bottom surface in a direction orthogonal to the thickness direction of the slider body and to the width direction,

a shaft hole for the connecting pin to be inserted is provided to the each of the pair of lateral walls, and

the first recess bottom surface of each of the pair of shoulders is located close to the lower vane in the thickness direction of the slider body with respect to the shaft hole of the pair of lateral walls.

7. A slider fastener comprising:

the slider according to claim 1 ; and

a pair of fastener stringers connected to the slider.
