Specifically, an appropriate rotation phase of the lever shaft 64 with respect to the bracket 52 is determined so that the first operating portion 76 is arranged in an appropriate state, and the lever shaft 64 is fixed to the bracket 52 by the fixing screw 78. The proper state of the first operation unit 76 is a state in which the first operation unit 76 is arranged in a direction that is easy for the rider to operate. Since the lever shaft 64 is fixed to the bracket 52 at an appropriate rotation phase, the operability of the first operation portion 76 is improved.　　[0057] As shown in Fig. 8, the first operating portion 76 is a hinge switch. The first operation portion 76 includes a switch 76A, a hinge shaft 76B, a main body portion 76C, an elastic member 76E, and a fixing member 76F. The switch 76A is, for example, a hinge type electric switch. The switch 76A is attached to the main body portion 76C via the hinge shaft 76B so as to be swingable about the hinge shaft 76B. The hinge shaft 76B is provided in the main body part 76C so as to be rotatable with respect to the main body part 76C, for example. The main body 76C is, for example, fixed to the lever shaft 64 and swings with respect to the bracket 52 together with the lever shaft 64. The main body portion 76C includes a hole portion 76D through which the lever shaft 64 can be inserted. The elastic member 76E is attached to the main body part 76C. The elastic member 76E applies elastic force to the switch 76A to restore the switch 76A to the initial position. An example of the shape of the fixing member 76F is a ring shape. The fixing member 76F is fixed to the main body portion 76C, and for example, a part of the elastic member 76E is sandwiched between the fixing member 76F and the main body portion 76C. By fixing the fixing member 76F to the main body portion 76C, the elastic member 76F is fixed to the main body portion 76C.　　[0058] The lever shaft 64 includes a first end 64A and a second end 64B. The first operating portion 76 is provided on at least one of the first end 64A and the second end 64B of the lever shaft 64. An example of the number of the first operation parts 76 is one. The first operation portion 76 is provided, for example, at the first end portion 64A of the lever shaft 64. In one example, the first end 64A is inserted through the bracket 52 and the hole 76D of the main body 76C, and is connected to the main body 76C. The rotation center axis C of the lever shaft 64 passes through the hole portion 76D of the main body portion 76C, the elastic member 76E, the fixing member 76F, and the switch 76A. The second end 64B of the lever shaft 64 is connected to the bracket 52 and is exposed, for example, on the second side surface 52B of the bracket 52. When the number of first operating parts 76 is two, one of the first operating parts 76 is provided on the first end 64A of the lever shaft 64, and the other first operating part 76 is provided on the second end of the lever shaft 64.端部64B.　　[0059] As shown in FIG. 9, when the brake operating portion 62 is operated by the rider, the brake lever 60 swings about the rotation center axis C of the lever shaft 64. The two-dot chain line shown in FIG. 9 shows the arrangement of the brake lever 60 in a state where the brake operating portion 62 is not operated. Since the lever shaft 64 is fixed to the bracket 52 by the fixing screw 78, even when the brake lever 60 swings, the lever shaft 64 does not swing relative to the bracket 52, and the first operating portion 76 can be maintained to be properly arranged status.　　[0060] (Fifth Embodiment) 　　 The brake operating device 50 of the fifth embodiment will be described with reference to Figs. 10 and 11. The same reference numerals as those in the first embodiment are assigned to the structures common to the first embodiment, and redundant descriptions are omitted.　　[0061] The first operating portion 66 of the fifth embodiment is provided on the front face 60A of the brake lever 60 and used to operate the bicycle assembly 36.
