The first positioning section 45P also stabilizes the cable connector 7A of the electrical cable 7 relative to the electrical connector port 45.

In the present embodiment, the electrical conductor 66E is provided at least partially within the inner surface 66A. The electrical conductor 66E is located partially within the inner surface 66A. The electrical conductor 66E is located partially outside the inner surface 66A.

The electrical conductor 66E is not provided within the projecting section 66P. However, the electrical conductor 66E can be provided entirely within the inner surface 66A if required and / or desired. The electrical conductor 66E can also be attached to other parts of the port cover 66 if required and / or desired.

[0248] In the present embodiment, the electrical conductor 66E is provided at least partially with the cover body 66B as a single, unified element.

The electrically conductive element 91 consists, for example, of electrically conductive rubber. The electrically conductive element 91 is compressed between the metal element 45B2 and the mounting surface 10A. Thus, the elastic deformation of the electrically conductive element 91 maintains contact between the electrically conductive element 91 and the metal element 45B2, as well as contact between the electrically conductive element 91 and the mounting surface 10A.

[0256] As in Fig. As shown in Figure 33, in the mounting state, where the housing 28 is attached to the rotary device 10 and the port cover 66 at least partially covers the electrical connector port 45, a fourth distance DS4 is defined between the electrically conductive element 90 and the mounting surface 28.

The wireless communicator WC1, the electronic control unit EC1, the force sensor 32, the position detector 38, the electrical power source 42, the power source holder 43, and the electrical connector port 45 are provided on the pedal axle 24B.

[0314] The wireless communicator WC1 is configured to wirelessly transmit rotation information INF4 with respect to the rotary device 410 (e.g., the pedal 24). The force sensor 32 is configured to detect the rotation information INF4. The force sensor 32 is configured to output a measured value indicating the force applied to the rotary device 410 in the direction of rotation D1 (see, e.g., Fig. 29).

[0315] The electronic control unit EC1 is configured to receive the rotation information INF4 determined by the force sensor 32. The electronic control unit EC1 is electrically connected to the force sensor 32 in order to receive the rotation information INF4 determined by the force sensor 32.

[0316] The rotation information INF4 contains the power INF41 applied to the rotating device 410 and a rotational speed INF42 of the rotating device 410. For example, the electronic control EC1 is configured to calculate the power INF41 applied to the rotating device 410 based on the torque applied to the rotating device 410 (e.g., the pedal 24) and the rotational speed INF42 of the rotating device 410. However, the electronic control EC1 can be configured to calculate the power INF41 applied to the rotating device 410 based on other data if needed and / or desired. For example, the electronic control EC1 can be configured to calculate an average of the power INF41 during one revolution of the crank arm 14.The electronic control EC1 can, for example, be set up to calculate the total power during one revolution of the crank assembly 13 by doubling the power INF41 at the single crank arm.

[0317] As in Fig. As can be seen in Figure 31, the electrical device 412 for the rotary device 410 of the muscle-powered vehicle 2 comprises a housing 428. The housing 428 is coupled to the pedal axle 24A (see, for example, Figure 31). Fig. 29). The wireless communicator WC1, the electronic control EC1, the force sensor 32, the position detector 38 and the electrical power source 42 are provided in the housing 428.

[0318] The description of electrical device 12 can be used as a description of electrical device 412 by replacing the reference numerals “INF1”, “INF11”, “INF12”, “10”, “12”, and “28” with “INF4”, “INF41”, “INF42”, “410”, “412”, and “428”. For the sake of brevity, it is not described in detail here.

[0319] In the first to fourth embodiments and their modifications, the external electrical device 8 is a separate device from the additional electrical device 6. However, the external electrical device 8 can be integrated with the additional electrical device 6 as a single device if required and / or desired.

[0320] At least one of the Fig. 11, Fig. 12, Fig. 14 and Fig. The 15 changes shown can be applied to the first to fourth embodiments and their modifications.

[0321] In each of the first embodiments and their modifications, the electrical device 12 is attached to the mounting surface 10A of the rotary device 10. However, the electrical device 12 can be attached to an inner surface of the rotary device 10 (e.g., an inner surface of the crank arm 14 or 18) if necessary and / or desired. In such modifications, the electrical device 12 is located in an interior space of the rotary device 10 (e.g., an interior space of the crank arm 14 or 18). The same applies to the second to fourth embodiments and their modifications.

[0322] In the present application, the term "comprehensive" and its derivatives, as used herein, are to be understood as open terms that specify the presence of the indicated features, elements, components, groups, integers, and / or steps, but do not exclude the presence of other unspecified features, elements, components, groups, integers, and / or steps. This concept also applies to words with similar meanings, such as the terms "have," "comprehensive," and their derivatives.

[0323] The terms “Glied”, “Abschnitt”, “Teil”, “Part”, “Element”, “Körper”, and “Struktur”, when used in the singular, have the dual meaning of a single part or a multitude of parts.

[0324] The ordinal numbers such as "first" and "second," as mentioned in the present application, are merely identifiers and have no further meaning, such as indicating a specific order or similar. Moreover, the term "first element," for example, does not in itself imply the presence of a "second element," and the term "second element" does not in itself imply the presence of a "first element."

[0325] The term “pair of”, as used here, can include the configuration in which the pair of elements has different shapes or structures, in addition to the configuration in which the pair of elements has similar shapes or structures.

[0326] The terms “a”, “one or more” and “at least one” can be used interchangeably here.

[0327] The phrase "at least one of," as used in this disclosure, means "one or more" of a desired selection. For example, the phrase "at least one," as used in this disclosure, means "only a single choice" or "both of two choices" when the number of choices is two. For example, the phrase "at least one," as used in this disclosure, means "only a single choice" or "any combination of two or more choices" when the number of choices is three or more. For example, the phrase "at least one of A and B" includes (1) A alone, (2) B alone, and (3) both A and B. The phrase "at least one of A, B, and C" includes (1) A alone, (2) B alone, (3) C alone, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all A, B, and C.In other words, the phrase “at least one of A and B” in this disclosure does not mean “at least one of A and at least one of B”.

[0328] Finally, terms such as "substantial," "approximately," and "about," as used here, signify a reasonable degree of deviation from the modified concept, such that the final result is not substantially altered. All numerical values ​​described in this application can be interpreted as including the terms "substantial," "approximately," and "about."

[0329] Naturally, in light of the above-mentioned teachings, numerous modifications and variations of the present invention are possible. It should therefore be understood that the invention, within the scope of the accompanying claims, can be exercised differently than specifically described herein.
