Wherein the surface member comprises: a first portion; and a second portion disposed so as to form a gap between the first portion and an outer peripheral surface of the strand. The layer has a first thickness between the strand and the surface member in the radial direction of the strand, and a second thickness between the strand and the gap in the radial direction. , And the second thickness is formed to be equal to or less than the first thickness. Since the wire and the surface member are bonded by the adhesive, the surface member is strongly fixed to the outer peripheral surface of the wire. Since the second thickness of the adhesive layer is equal to or less than the first thickness, the adhesive layer does not easily come into contact with the inner peripheral surface of the outer case. Further, more lubricant can be arranged in the gap. Therefore, the resistance when the inner wire for the bicycle moves with respect to the outer case is reduced.

  [2] In the inner wire for a bicycle according to [1], the surface member is spirally wound around the outer peripheral surface of the element wire. For this reason, the surface member is more strongly fixed to the outer peripheral surface of the strand.

  [3] In the inner wire for a bicycle according to the above [1] or [2], a cross section along a radial direction of the surface member is formed to be substantially circular. For this reason, the contact area between the surface member and the outer case is reduced, and the resistance when the inner wire for the bicycle moves relative to the outer case is reduced.

  [4] In the inner wire for a bicycle according to any one of [1] to [3], the size of the gap in a direction along a center axis of the strand is smaller than a minimum diameter of the surface member. Is also small. For this reason, the area of the wire and the surface member bonded by the adhesive layer is increased, and the surface member is more strongly fixed to the outer peripheral surface of the wire.

For this reason, the contact area between the surface member and the outer case is reduced, and the resistance when the inner wire for the bicycle moves relative to the outer case is reduced.

  [6] In the inner wire for a bicycle according to any one of [1] to [5], an outer peripheral surface of the surface member includes an adhesive surface to which the adhesive is applied, and the adhesive surface includes: The outer peripheral surface of the surface member is provided at a portion facing the outer peripheral surface of the element wire. For this reason, the surface member is more strongly fixed to the outer peripheral surface of the strand.

  [7] In the inner wire for a bicycle according to any one of [1] to [6], a size of the gap in a direction along a center axis of the strand is larger than the first thickness. . For this reason, the contact area between the surface member and the outer case is reduced, and the resistance when the inner wire for the bicycle moves relative to the outer case is reduced.

Further, when the surface members are arranged on the element wire, more lubricant can be arranged between the surface members. Therefore, the resistance when the inner wire for the bicycle moves with respect to the outer case is reduced.

In the second step, the surface member 40 to which the adhesive 38 has been applied is arranged on the outer peripheral surface 34 of the strand 32. The strand 32 in the second step is the strand 32 in which the strands 32A to 32C are twisted. The description of the step of twisting the strands 32A to 32C is omitted. In the second step, for example, the surface member 40 is spirally wound around the outer peripheral surface 34 of the strand 32.
