The brake disc rotor 2 is rotatable relative to the bicycle frame 1 in the direction of rotation D about the axis of rotation RA. Rotation direction D contains positive rotation The direction D1 and the negative rotation direction D2 opposite to the positive rotation direction D1. The positive rotational direction D1 of the brake disc rotor 2 is defined as the direction in which the brake disc rotor 2 rotates when the bicycle moves forward. The negative rotational direction D2 of the brake disc rotor 2 is defined as the direction in which the brake disc rotor 2 rotates when the bicycle moves rearward. In the illustrated embodiment, the disc brake caliper 10 is a front disc brake that is mounted to the front fork 1a of the bicycle frame 1. However, the disc brake caliper 10 can be applied to a rear disc brake. The disc brake caliper 10 is constructed to be actuated by hydraulic fluid supplied from an operating device (not shown). Since the operating device contains structures known in the bicycle field, the operating device will not be described and/or illustrated for the sake of brevity.

In this case, the following terms are "before", "after", "forward", "backward", "left", "right", "horizontal", "up", "down" and any other similar Directional terms refer to those directions that are determined by a rider sitting on a bicycle saddle (not shown) facing, for example, a handlebar (not shown). Therefore, these terms should be interpreted by the user relative to the bicycle in an upright riding position on a horizontal surface when used to describe the disc brake caliper.

The mounting portion M31 of the bicycle frame 1 includes a pair of mounting through holes M33 and M34 provided on the mounting surface M32. Class snail The bolt 30 and the mounting member 32 extend through the mounting through holes M33 and M34.

As seen in Figure 15, the opposing surface 36 is disposed on the first coupling portion 352. The facing surface 36 is constructed to face the mounting portion M31 of the bicycle frame 1 to which the disc brake caliper 310 can be attached. In the illustrated embodiment, the opposing surface 36 contacts the mounting portion M31 in a state where the caliper body 312 is attached to the mounting portion M31.

With the disc brake caliper 310, an attachment structure 38 to which the assembly bolt 30 is attached is provided on the opposite surface 36 which is constructed to face the mounting portion M31 of the bicycle frame 1. Therefore, at least a portion of the assembly bolt (connecting member) 30 and/or the fluid hose 28 is less likely to be seen in a state where the disc brake caliper 310 is mounted to the mounting portion M31 of the bicycle frame 1. This allows the appearance of the disc brake caliper 310 to be simplified.

In addition, since the caliper main body 312 is directly coupled to the mounting portion M31 of the bicycle frame 1 using the arranging assembly bolt 30 without the base member, one of the third mounting hole 12a and the mounting member 32, And the base member 14 (Fig. 4) can be omitted. This allows the structure of the disc brake caliper 310 to be simplified.

Fourth embodiment

A disc brake caliper 410 according to a fourth embodiment will be described below with reference to FIG. The disc brake caliper 410 has substantially the same configuration as the disc brake caliper 10 except for the structure of the caliper body and the base member. Therefore, having substantially the same effect as the elements in the first embodiment or Functional elements are given the same element symbols herein and will not be described and/or illustrated again for the sake of brevity.

As seen in Fig. 16, the base member 14 (Fig. 3) according to the first embodiment is omitted from the disc brake caliper 10. The disc brake caliper 410 includes a caliper body 412. The caliper body 412 includes a facing surface 36 and an attachment structure 38. The caliper body 412 further includes first mounting holes 414a and 414b (hereinafter simply referred to as mounting holes 414a and 414b) provided on the opposing surface 36. The first mounting members 16 (hereinafter simply referred to as mounting members 16) extend through the mounting holes 414a and 414b, respectively. The facing surface 36 is constructed to face the mounting portion M1 of the bicycle frame 1 (Fig. 3). Since the base member 14 according to the first embodiment is omitted from the disc brake caliper 10, the opposite surface 36 is constructed to contact the mounting portion M1 of the bicycle frame 1 (Fig. 3).

With the disc brake caliper 410, an attachment structure 38 to which the assembly bolt 30 is attached is provided on the opposite surface 36 which is constructed to face the mounting portion M1 of the bicycle frame 1. Therefore, at least a portion of the assembly bolt (connecting member) 30 and/or the fluid hose 28 is less likely to be seen in a state where the disc brake caliper 410 is mounted to the mounting portion M1 of the bicycle frame 1. This allows the appearance of the disc brake caliper 410 to be simplified.

In the above embodiments, the term "attached" or "attached" as used herein, encompasses a configuration in which an element is directly attached to another element by attaching it directly to another element, The component is indirectly attached to the configuration of the other component via one or more intermediate members, and An element is integral with another element, that is, one element is essentially a configuration of a part or portion of another element.
