[0010] Hereinafter, an embodiment will be described with reference to the drawings.

[0011] First Embodiment (Overall composition) Fig. 1 is a side view of a motorcycle 1 according to the first embodiment. Fig. 2 is a top view of the motorcycle 1 shown in Fig. 1. Note that Fig. 2 omits elements such as an outer cover 30, a casing 70, and an inner cover 51, which will be described later. As shown in Fig. 1, the motorcycle 1 is an example of a saddle-ride vehicle on which a rider straddles. Directions in the following description are based on the direction as seen from the rider of the motorcycle 1, with the fore-and-aft direction corresponding to the vehicle length direction and the left-and-right direction corresponding to the vehicle width direction.

[0012] Motorcycle 1 includes a front wheel 2, a rear wheel 3, a body frame 4, a front suspension 5 connecting the front wheel 2 to a front portion of body frame 4, and a rear suspension (not shown) connecting the rear wheel 3 to a rear portion of body frame 4. In this embodiment, the front wheel 2 is a driven wheel, and the rear wheel 3 is a driving wheel. Front suspension 5 is connected to brackets 6 arranged at intervals in the vertical direction. A steering shaft connected to bracket 6 is supported on a head pipe 4a that is part of body frame 4 so as to be angularly displaceable.

[0013] A steering wheel 7 that the driver grips is provided on the steering shaft. A seat 9 in which the driver sits is disposed behind the steering wheel 7. The seat 9 is supported by the body frame 4.

[0014] An electric motor 10, which serves as a driving source for traveling, and a battery case 20 are arranged between the front wheels 2 and the rear wheels 3. The electric motor 10 and the battery case 20 are each supported by the body frame 4. The electric motor 10 generates a rotational driving force that is transmitted to the rear wheels 3, which are the driving wheels. The electric motor 10 is located below the seat 9. The electric motor 10 is also located forward of the front end 9a of the center part of the seat 9 in the left-right direction (hereinafter referred to as the "seat front end").

[0015] Electric power is supplied to the electric motor 10 from a battery pack 11 (see FIG. 2) that is housed in a battery case 20 (corresponding to a battery support) that forms a housing chamber. An outer lid 30 is connected to the battery case 20, and the battery pack 11 can be attached to and detached from the motorcycle 1 by opening and closing the outer lid 30.

[0016] The battery pack 11 has a substantially rectangular parallelepiped shape. In this embodiment, as shown in Fig. 2, the battery case 20 can accommodate two battery packs 11 of the same shape arranged side by side in the left-right direction.

[0017] (battery case) FIG. 3 is a side cross-sectional view showing an enlarged view of the vicinity of the battery case 20 when the outer lid 30 is in a closed state. FIG. 4 is a side cross-sectional view showing an enlarged view of the vicinity of the battery case 20 when the outer lid 30 is in an open state. The battery case 20 has an accommodation space S that accommodates the battery pack 11. The battery case 20 has an opening P1 (see FIG. 2) that exposes the accommodation space S, and the opening P1 can be opened or closed by the outer lid 30, which is a lid body. The opening P1 is an opening for attaching or detaching the battery pack 11. That is, the opening P1 has a size that allows the battery pack 11 to pass through. The opening P1 also opens upward. That is, the battery pack 11 is inserted into or removed from the battery case 20 by passing through the opening P1.

[0018] As shown in FIG. 3, the storage space S is surrounded by a battery case 20 and an outer lid 30 in front of the seat 9 in the front-to-rear direction. The battery case 20 includes a case main body 21 that opens upward and a frame-shaped base 22. The base 22 is connected to the case main body 21 so as to surround the upper end of the case main body 21. The base 22 includes an opening P1 (hereinafter also referred to as an "upper opening P1") that is closed by the outer lid 30, and a lower opening P2 located below the upper opening P1. The case main body 21 and the base 22 are connected to each other so that the opening of the case main body 21 and the lower opening P2 of the base 22 coincide with each other.

[0019] The storage space S is roughly divided into multiple spaces by the inner lid 51 and the casing 70 arranged in the storage space S. For example, the inner lid 51 is arranged so as to close the opening of the case body 21, i.e., the lower opening P2 of the base 22. The inner lid 51 also divides the storage space S into a first space S1 surrounded by the case body 21 and the inner lid 51, and the remaining space. The first space S1 is a space occupied by the stored battery pack 11.

[0020] A casing 70 is placed on the upper surface of the inner lid 51. The casing 70 is concave and open upward. The casing 70 has a bottom wall 71 parallel to the inner lid 51, a first partition wall 72 rising upward from the front edge of the bottom wall 71, and a second partition wall 73 rising upward from the rear edge of the bottom wall 71. The space surrounded by the inner lid 51, the base 22, and the outer lid 30 in the closed state (i.e., the remaining space described above) is partitioned by the first partition wall 72 and the second partition wall 73 into three spaces: a second space S2, a third space S3, and a fourth space S4.

[0021] The second space S2, the third space S3, and the fourth space S4 are aligned in the front-to-rear direction. The second space S2 is a space sandwiched between the first partition wall 72 and the second partition wall 73 in the front-to-rear direction. The second space S2 is a space inside the casing 70 and functions as a luggage storage space for storing luggage as storage items. The third space S3 is a space in front of the second space S2, and the fourth space S4 is a space behind the second space S2. The third space S3 accommodates the locking mechanism 40 and the engaging member 52 (described below), and the fourth space S4 accommodates the hinge shaft 32 and the retainer 53 (described below). The third space S3 and the fourth space S4 may also be referred to as mechanism element storage spaces that accommodate various elements of various mechanisms. In particular, the fourth space S4, which accommodates the hinge shaft 32, may also be referred to as a shaft storage space.

[0022] The casing 70 has a pair of side walls 74. One of the pair of side walls 74 connects the right ends of the first partition wall 72 and the second partition wall 73, and the other connects the left ends of the first partition wall 72 and the second partition wall 73. A flange 75 extending outward in the vehicle width direction is connected to the upper end of each side wall 74. The flange 75 abuts against a part of the lower surface of the outer lid 30 in the closed state and is pressed from above. This prevents the casing 70 from moving up and down within the storage space S.

[0023] The case body 21 is box-shaped and open upward. The case body 21 includes a rectangular bottom wall 21a that supports the underside of the battery pack 11 and a peripheral wall 21b that rises from the entire periphery of the bottom wall 21a. The battery case 20 is inclined rearward relative to the vertically upward direction. More specifically, the bottom wall 21a is inclined upward toward the front, and the rear portion of the peripheral wall 21b is inclined upward toward the rear. The rear end of the upper opening P1 of the base 22 is located behind the rear end of the opening edge of the case body 21. In this way, the case body 21 is positioned so that the battery pack 11 can be inserted and removed obliquely.

[0024] The case body 21 has a first space S1 (hereinafter, may also be referred to as a "battery space"). The case body 21 has a flange 21c around an opening located at the upper end of the peripheral wall 21b. The flange 21c is fixed to the base 22 by fastening means such as bolts.

[0025] A support-side connector 21d is disposed on the upper surface of the bottom wall 21a. A battery-side connector 11a is disposed on the lower surface of the battery pack 11. The support-side connector 21d and the battery-side connector 11a are configured so that the terminals of the support-side connector 21d and the battery-side connector 11a come into contact with each other and can be electrically connected when the battery pack 11 is guided downward toward the bottom wall 21a by the peripheral wall 21b.

[0026] In this way, electrical connection between the support-side connector 21d and the battery-side connector 11a can be achieved by the simple method of guiding the battery pack 11 downward by the peripheral wall 21b. In other words, the terminals of the support-side connector 21d and the battery-side connector 11a can be released from contact with each other simply by the battery pack 11 moving upward inside the battery case 20. However, because the pressing mechanism 50 described below suppresses the up and down movement of the battery pack 11, the power supply from the battery pack 11 to the electric motor 10 is prevented from being cut off.

[0027] A harness cover 25 is attached from below to the bottom wall 21a of the case body 21. The harness cover 25 is concave and attached to the case body 21 by fastening means such as bolts to form a harness space that partially covers the harness 26 extending from the support-side connector 21d through the bottom wall 21a. Components other than the harness, such as a step-down circuit board that reduces the voltage of the power output from the battery pack 11, may be disposed in the harness space. The harness cover 25 is separate from the case body 21, but the harness cover 25 and the case body 21 may also be molded integrally.

[0028] The frame-shaped base 22 includes an upper base frame 23 that constitutes the upper portion of the base 22 and a lower base frame 24 that constitutes the lower portion of the base 22. The lower end of the upper base frame 23 and the upper end of the lower base frame 24 are connected to each other. As shown in FIG. 2 , the upper base frame 23 includes an upper opening P1 that is closed by the outer lid 30, and the lower base frame 24 includes a lower opening P2 located below the upper opening P1. The lower opening P2 is closed by the inner lid 51. The thickness dimension of the outer lid 30 (corresponding to the lid body) is smaller than the thickness dimension of the inner lid 51 (corresponding to the abutting member). In other words, the outer lid 30 is thinner than the inner lid 51. This allows the inner lid 51 to more easily withstand a pressing reaction force and reduces the weight of the outer lid 30.

[0029] The upper base frame 23 is annular and has a generally elliptical outer shape when the motorcycle 1 is viewed from above (see also FIG. 2). The upper base frame 23 and the outer lid 30 that closes the upper opening P1 form a dome shape that opens downward. The lower base frame 24 is annular and has a generally elliptical outer shape when the motorcycle 1 is viewed from above. The lower base frame 24 and the inner lid 51 that closes the lower opening P2 form a concave shape that opens upward.

[0030] The base 22 includes a protruding portion 23a that protrudes diagonally forward and upward from the seat front end 9a. The protruding portion 23a is located near the center of the upper base frame 23 in the left-right direction and is located rearward of the upper opening P1. The protruding portion 23a has a shape in which the center portion in the vehicle width direction bulges rearward. The protruding portion 23a functions as a restricting portion that restricts the front end position of the rider's seating range. The protruding portion 23a serves to support the rider so that they do not deviate forward from the seating range of the seat 9 when the rider is subjected to a forward inertial force during deceleration of the motorcycle 1.

[0031] (Opening and closing mechanism) 5 is an enlarged side cross-sectional view of the vicinity of the upper portion of the battery case 20. The motorcycle 1 is provided with an opening / closing mechanism 31 that opens and closes the outer lid 30. The opening / closing mechanism 31 rotates the outer lid 30 about a hinge shaft 32 between an open position that opens the storage space S upward and a closed position that covers the storage space S from above. As shown in FIG. 5, the opening / closing mechanism 31 includes the hinge shaft 32, a hinge support 33, and an arm 34.

[0032] The hinge shaft 32 is an axis that serves as the center of rotation of the outer lid 30. The hinge shaft 32 extends in the left-right direction. The hinge shaft 32 is located above and forward of the seat front end 9a. The hinge shaft 32 is located in the left-right center so as to pass through the center plane of the motorcycle 1 in the left-right direction. The hinge shaft 32 is also located at a position spaced at least one way below and rearward from the left-right center portion of the outer lid 30 in the closed position, i.e., the closed state. In this embodiment, as shown in FIG. 3 , the rear end 30a of the left-right center portion of the outer lid 30 in the closed state is the lowest end of the left-right center portion of the outer lid 30, and the hinge shaft 32 is located at a position spaced downward from the rear end 30a. The hinge shaft 32 is also located at the same position as the rear end 30a in the front-rear direction.

[0033] The hinge support 33 is fixed to the base 22. The hinge support 33 connects the base 22 and the hinge shaft 32 to each other and supports the hinge shaft 32. The hinge shaft 32 and the hinge support 33 are located above the body frame 4 and below the left-right central portion of the outer lid 30 in the closed state. In other words, the hinge shaft 32 and the hinge support 33 can be located closer to the body frame 4 than the outer lid 30, making it easier to increase the support rigidity of the hinge.

[0034] The arm 34 connects the outer cover 30 and the hinge shaft 32 and rotates together with the outer cover 30 around the hinge shaft 32. The arm 34 is located on the central plane of the motorcycle 1 in the left-right direction, i.e., in the center in the vehicle width direction. As described above, the protruding portion 23a has a shape in which the center in the vehicle width direction bulges rearward. Therefore, by positioning the arm 34 in the center in the vehicle width direction, the hinge shaft 32 can be located close to the body frame 4, making it easier to increase the support rigidity of the hinge.

[0035] The base end 34a of the arm 34, which is the rear end when the outer lid 30 is in the closed position, is connected to the hinge shaft 32, and the tip end 34b, which is the front end of the arm 34 when the outer lid 30 is in the closed position, is connected to the underside of the outer lid 30 in the closed state. The outer lid 30 is connected to the battery case 20, bypassing the pressing mechanism 50 described below. Because the outer lid 30 is angularly displaced around the hinge shaft 32, which is the rear end of the arm 34, as the center of rotation, the outer lid 30 is configured to be positionable at a position spaced above the base 22 in the open state. The arm 34 is shaped so that it does not interfere with the base 22 even when the outer lid 30 is moved between the open position and the closed position. The arm 34 has a bent shape such that, when viewed in the left-right direction, the frontmost end of the arm 34 is located forward of the front end of the protruding portion 23a of the base 22 when the outer lid 30 is in the open position (see FIG. 4).

[0036] The shape of the base 22 and the shape of the arm 34 that prevents interference with the base 22 will be described in more detail. The protruding portion 23a of the base 22 includes a portion 23a1 (hereinafter also referred to as the "exposed portion") that is exposed when viewed from behind or above when the outer lid 30 is in the closed position, and a portion 23a2 (hereinafter also referred to as the "non-exposed portion") that extends forward from the front end of the exposed portion 23a1 and is covered from above by the outer lid 30 in the closed position. The exposed portion 23a1 blocks the gap between the rear end 30a of the outer lid 30 in the closed position and the front end 9a of the seat, and functions as a restricting portion that restricts the front end position of the driver's seating range. The exposed portion 23a1 (specifically, the surface of the exposed portion 23a1 facing forward) and the hinge shaft 32 face each other in the front-to-rear direction. That is, the exposed portion 23a1 overlaps with the hinge shaft 32 in the front-rear direction so as to cover the entire hinge shaft 32 when viewed from behind.

[0037] As shown in FIG. 5 , a seal 27 is attached to the outer lid 30. The seal 27 has a ring shape that extends along the periphery of the outer lid 30. The rear end of the seal 27 comes into close contact with the base 22 when the outer lid 30 is in the closed position, preventing fluid from passing between the outer lid 30 and the base 22. When the outer lid 30 is in the closed position, the seal 27 comes into close contact with the upper surface of the non-exposed portion 23a2. For this reason, the non-exposed portion 23a2 can also be referred to as a seal receiving portion. The portion of the non-exposed portion 23a2 with which the seal 27 comes into close contact is formed in a concave shape. Specifically, the portion of the non-exposed portion 23a2 with which the seal 27 comes into close contact when the outer lid 30 is in the closed position protrudes downward compared to the adjacent portion of the non-exposed portion 23a2 located rearward.

[0038] In this example, when the outer lid 30 is in the closed position, the arm 34 is formed in a U-shape that protrudes downward. Specifically, the arm 34 extends downward as it moves forward from the base end 34a, reaching a lower end located in the middle in the front-to-rear direction. As it moves further forward from the lower end, it extends upward to a tip end 34b, which is the front end. By forming the arm 34 in this U-shape, interference between the protruding portion 23a (more specifically, the non-exposed portion 23a2) and the arm 34 can be prevented, and the rotation range of the outer lid 30 can be expanded.

[0039] When the outer lid 30 is in the closed state, the tip end 34b of the arm 34 (the connection portion with the outer lid 30) is positioned above the base end 34a (the connection portion with the hinge shaft 32) of the arm 34. By positioning the hinge shaft 32 below the lower end of the outer lid 30, the outer lid 30 can be moved away from the upper opening P1 when the outer lid 30 is fully opened, and interference between the outer lid 30 and the battery pack 11 can be reduced when the battery pack 11 is inserted or removed.

[0040] The second partition wall 73 of the casing 70 is formed with a notch 73a through which the arm 34 is inserted so that the casing 70 does not interfere with the arm 34.

[0041] The opening / closing mechanism 31 also includes a stopper structure that limits the rotation range of the outer lid 30. Specifically, the base end 34a of the arm 34 has a protrusion 35 that protrudes radially from the hinge shaft 32. The protrusion 35 rotates together with the rotation of the outer lid 30 and abuts against a receiving portion 36 fixed to the base 22 when the outer lid 30 is in an open position rotated a predetermined angle from the closed position. The protrusion 35 and the receiving portion (stopper) 36 constitute a stopper structure, thereby limiting the rotation range of the outer lid 30. The position of the protrusion 35 is adjusted so that, when the outer lid 30 is moved to the open position, the arm 34 does not come into contact with the base 22 and the rear end of the outer lid 30 does not come into contact with the protruding portion 23a. By arranging a stopper structure that limits the rotation range of the outer lid 30 around the hinge shaft 32, the fourth space S4, which is the space covered by the protruding portion 23a, can be effectively utilized.

[0042] The motorcycle 1 also includes a lock mechanism 40. The lock mechanism 40 holds the outer lid 30 in the closed position. The lock mechanism 40 includes a socket 41, a lock moving part 42, and a lock fixing part 43. The socket 41 is provided in the front portion of the base 22, more specifically, in the front portion of the upper base frame 23. The lock moving part 42 is movable between a locked position and an unlocked position when the rider inserts a key into the socket 41 and operates it. The lock fixing part 43 engages with the lock moving part 42 in the locked position to prevent the outer lid 30 from moving from the closed position to the open position. The lock moving part 42 is attached to the upper base frame 23, and the lock fixing part 43 is fixed to the outer lid 30. In this way, the lock mechanism 40 can be switched between a locked state in which the outer lid 30 is held in the closed position and an unlocked state in which the state in which the outer lid 30 is held in the closed position is released.

[0043] In this embodiment, the base 22, outer lid 30, opening / closing mechanism 31, and locking mechanism 40 are unitized as a cover unit. Furthermore, the cover unit is fixed to the case body 21, i.e., the base 22 is fastened to the flange 21c of the case body 21, thereby unitizing the cover unit as a battery housing unit. Unitizing the elements related to the attachment and detachment of the battery pack 11 in this manner facilitates the design and assembly of the motorcycle 1 to facilitate the attachment and detachment of the battery pack 11. For example, a design can be easily made in which the upper opening P1 is positioned in the direction in which the battery pack 11 is removed from the case body 21, eliminating the need to change the direction of removal of the battery pack 11 midway to avoid elements of the cover unit, such as the arm 34 (see the two-dot chain line in FIG. 4 ). For example, the positions of the lower opening P2 and the upper opening P1 of the base 22 relative to the opening edge of the case body 21 can be easily adjusted.

[0044] (Pressing mechanism) The motorcycle 1 includes a pressing mechanism 50. The pressing mechanism 50 is disposed in the accommodation space S. The pressing mechanism 50 includes an inner lid 51, an engaging member 52, and a retainer 53.

[0045] The inner lid 51 is an abutting member that can abut against the battery pack 11 when it is housed in the housing space S of the battery case 20. In this embodiment, when the battery pack 11 is housed in the battery case 20, the top of the battery pack 11 protrudes slightly upward from the opening of the case body 21. Therefore, the inner lid 51 has a concave shape that opens downward so as to close the battery space S1 while covering the portion of the battery pack 11 that protrudes from the case body 21. The concave surface of the inner lid 51 facing downward abuts against the top surface of the housed battery pack 11. Hereinafter, the position of the inner lid 51 when it abuts against the battery pack 11 will be referred to as the abutting position or the closed position.

[0046] In this embodiment, the battery case 20 supports two battery packs 11 lined up in the left-right direction from below so that the heights of their upper surfaces are the same, and the upper surfaces of both of the two battery packs 11 abut against one inner lid 51.

[0047] The inner lid 51 is detachable from the battery case 20. FIG. 6 is a top view of the inner lid 51. The inner lid 51 includes a lid main body 51a, an engaged portion 51b, and a support portion 51c. The lid main body 151a closes the opening P2 when the inner lid 151 is in the abutting position. The engaged portion 51b is fixed to the front end of the lid main body 51a. The engaged portion 51b is engageable with an engaging member 52 fixed to the battery case 20. The engaged portion 51b has a rod shape extending in the left-right direction. Hereinafter, the engaged portion 51b may also be referred to as an engaged shaft 51b.

[0048] The engaging member 52 has an engaging structure that allows it to be attached to and detached from the inner lid 51. With the engaged shaft 51b engaged with the engaging member 52, the inner lid 51 is rotatable about the axis C1 of the engaged shaft 51b. Specifically, the engaging member 52 is disposed in front of the lower opening P2 in the base 22 (more specifically, the lower base frame 24). The engaging member 52 is disposed within the third space S3. The engaging member 52 is fixed to the base 22 and has a hook shape. Hereinafter, the engaging member 52 may also be referred to as an engaging hook 52. By hooking the engaged shaft 51b of the inner lid 51 onto the engaging hook 52, the inner lid 51 becomes rotatable about the axis C1 of the engaged shaft 51b. By rotating, the inner lid 51 abuts against the battery pack 11 and closes the battery space S1, or moves away from the battery pack 11 and opens the battery space S1.

[0049] The support portion 51c is fixed to the rear end portion of the lid main body 51a and supports a compression spring 61, which is a component of the retainer 53 and will be described later.

[0050] 5, when the inner lid 51 is in the abutting position, the retainer 53 is disposed behind the lower opening P2 in the base 22 (more specifically, the lower base frame 24). In other words, the retainer 53 is disposed on the side where the upper surface of the battery pack 11 slopes downward. The retainer 53 is disposed on the same side as the hinge shaft 32 with respect to the battery pack 11. In other words, when the casing 70 is disposed in the accommodation space S, the retainer 53 is accommodated in the fourth space S4, similar to the hinge shaft 32 of the opening / closing mechanism 31. For this reason, the hinge shaft 32 and the retainer 53 of the pressing mechanism 50 are located in positions hidden by the second partition wall 73, that is, in positions that are difficult for a user to see simply by opening the outer lid 30.

[0051] The retainer 53 holds the inner lid 51, which is in contact with the battery pack 11, in a state in which it is pressed toward the battery pack 11. That is, the retainer 53 has a pressing function that presses the inner lid 51 downward when the inner lid 51 is in the contact position. The retainer 53 also has a locking function that locks the inner lid 51 to the battery case 20 when the inner lid 51 is in the contact position.

[0052] The retainer 53 includes a compression spring 61, a first spring seat 62, a second spring seat 63, an operating member 64, and a locked portion 68. Of the components of the retainer 53, the compression spring 61, the first spring seat 62, the second spring seat 63, and the operating member 64 are supported by the support portion 51c of the inner lid 51 and can move integrally with the inner lid 51. The compression spring 61 is a coil spring. The first spring seat 62 and the second spring seat 63 are annular. The operating member 64 is a member that is operated by the user.

[0053] Of the components of the retainer 53, the locked portion 68 is provided on the battery case 20. Specifically, the locked portion 68 is disposed on the lower base frame 24, behind the opening P2 of the lower base frame 24. The locked portion 68 is located at a position overlapping with the upper opening P1 when the motorcycle 1 is viewed from above (see FIG. 2). In other words, the retainer 53 including the locked portion 68 is located at a position overlapping with the upper opening P1 when the motorcycle 1 is viewed from above. Therefore, the retainer 53 is located in a position that is easily accessible to the user.

[0054] The locked portion 68 is locked by a locking portion 66b (described later) of the operating member 64. In this embodiment, the locked portion 68 is a hole extending in a predetermined direction. For example, the locked portion 68 is shaped like an elongated hole or a keyhole. Hereinafter, the locked portion 68 may also be referred to as a locked hole 68. In this example, the locked hole 68 extends in the left-right direction, but it may also extend in the front-rear direction, for example.

[0055] As shown in Fig. 5, the first spring seat 62 receives a first end 61a of the compression spring 61, and the second spring seat 63 receives a second end 61b of the compression spring 61. As shown in Fig. 5, when the inner lid 51 is in the abutting position, the first end 61a is the lower end of the compression spring 61, and the second end 61b is the upper end of the compression spring 61. In other words, when the inner lid 51 is in the abutting position, the first spring seat 62 is located below the compression spring 61, and the second spring seat 63 is located above the compression spring 61.

[0056] The first spring seat 62 is fixed to the inner lid 51. Specifically, the support portion 51c of the inner lid 51 includes a cylindrical tube portion 101 that is open upward and has a bottom, and the first spring seat 62 is disposed on a bottom 102 of the tube portion 101. The compression spring 61 is accommodated in the tube portion 101 of the support portion 51c so that the first spring seat 62 receives a first end 61a of the compression spring 61. That is, the inner lid 51 has an accommodation portion (the tube portion 101 in this example) that accommodates the compression spring 61. The first spring seat 62 may be formed as a part of the inner lid 51. A through hole 103, through which a cam support 66 (described later) is inserted, is formed in the bottom 102 of the tube portion 101 of the support portion 51c, in which the first spring seat 62 is disposed.

[0057] The second spring seat 63 is connected to the inner lid 51 so as to be movable relative to the inner lid 51. In this embodiment, the second spring seat 63 is connected to the inner lid 51 via an operating member 64.

[0058] The operating member 64 includes a cam lever 65 and a cam support 66. The cam lever 65 is disposed on the opposite side of the second spring seat 63 from the compression spring 61. The second spring seat 63 is sandwiched between the cam lever 65 and the compression spring 61. The cam lever 65 is supported by the cam support 66 via a support shaft 67 extending in the left-right direction so as to be rotatable about an axis C2 of the support shaft 67.

[0059] The cam lever 65 includes a lever portion 65a that is the portion that the user touches with their hand, and a pressing portion 65b that is displaced when the lever portion 65a is operated. The cam lever 65 has a shape that extends radially from the support shaft 67 to make it easy for the user to operate, and this extended portion is the lever portion 65a. The lever portion 65a corresponds to the operator. The pressing portion 65b is a curved portion whose distance from the support shaft 67 changes in accordance with the rotation angle of the cam lever 65 when viewed in the direction of the axis C2 of the support shaft 67.

[0060] The pressing portion 65b presses the second spring seat 63 toward the compression spring 61. By rotating the cam lever 65 about the axis C2, the pressing portion 65b can be displaced between a pressing position where it presses the inner lid 51 against the battery pack 11 and a pressure release position where it releases the pressing force when it is in the pressing position. The state of the retainer 83 when the pressing portion 65b is in the pressing position is referred to as a pressing state, and the state of the retainer 83 when the pressing portion 65b is in the pressure release position is referred to as a pressure release state. In this embodiment, the pressing portion 65b in the pressure release position does not generate a pressing force that presses the inner lid 51 against the battery pack 11. However, the pressing portion 65b in the pressure release position may generate a pressing force that is lower than the pressing force generated when the pressing portion 65b is in the pressing position.

[0061] The cam support 66 is connected to the inner lid 51 and supports the cam lever 65 via a support shaft 67. The cam support 66 has a rod-shaped portion 66a extending along the axis C3 of the cylindrical portion 101. The support shaft 67 is supported on one end of the rod-shaped portion 66a. The rod-shaped portion 66a is inserted radially inward of the second spring seat 63, the compression spring 61, and the first spring seat 62. The rod-shaped portion 66a also passes through a through-hole 103 in the bottom 102 of the cylindrical portion 101 of the support portion 51c.

[0062] The cam support 66 has a locking portion 66b, which is a protrusion that protrudes from the other end of the rod-shaped portion 66a in a direction perpendicular to the axis C3. The locking portion 66b is located at a position that protrudes from the through-hole 103 of the rod-shaped portion 66a on the side opposite to the compression spring 61. In other words, the locking portion 66b is located below the bottom 102 of the cylindrical portion 101.

[0063] When the locking portion 66b is rotated about the axis C3 and is in a predetermined unlocked position, the locking portion 66b can be inserted through the locking hole 68. In this embodiment, the unlocked position is a position where the extension direction of the locking hole 68 and the protruding direction of the locking portion 66b match. In this example, the locking hole 68 extends in the left-right direction, so when the protruding direction of the locking portion 66b matches the left-right direction, the locking portion 66b can be inserted through the locking hole 68. When the locking portion 66b is rotated about the axis C3 and is in a locked position, which is a position other than the unlocked position, the locking portion 66b cannot be inserted through the locking hole 68. That is, by operating the operating member 64 to pass the engaging portion 66b through the engaging hole 68, the engaging portion 66b is rotated around the axis C3 so that the engaging portion 66b cannot pass through the engaging hole 68, and the inner lid 51 is engaged so that it does not move away from the engaging hole 68.

[0064] Furthermore, a guide portion 66c is provided on the portion of the rod-shaped portion 66a that protrudes downward from the through-hole 103. The guide portion 66c is flange-shaped and comes into contact with the periphery of the locked hole 68 when locking or unlocking is performed by the locking portion 66b, thereby guiding the rotation of the operating member 64 about the axis C3. For example, the dimension between the guide portion 66c and the locking portion 66b roughly matches the dimension of the locked hole 68 in the penetration direction.

[0065] The guide portion 66c has a size or shape that prevents it from being inserted into either the through-hole 103 or the locked hole 68. Therefore, when the operating member 64 is lifted upward, the inner lid 51 is supported by the guide portion 66c and is also lifted. The operating member 64 is connected to the inner lid 51 so as to be displaceable relative to the inner lid 51. For example, the operating member 64 is connected to the support portion 51c of the inner lid 51 so as to be rotatable around the axis C3 of the cam support 66. Furthermore, the operating member 64 is connected to the support portion 51c of the inner lid 51 so as to be displaceable relative to the inner lid 51 in the direction of the axis C3 of the cam support 66.

[0066] In this pressing mechanism 50, by operating the cam lever 65, it is possible to both lock the inner lid 51 to the battery case 20 and press the inner lid 51 downward. With the inner lid 51 in the abutting position, more specifically, with the locking portion 66b passing through the locking hole 68, the cam lever 65 is operated to rotate the locking portion 66b about the axis C3. When the locking portion 66b is displaced from the unlocked position to the locked position, the locking portion 66b can no longer be inserted through the locking hole 68, and the locking hole 68 is locked by the locking portion 66b. As a result, the position of the support shaft 67 is fixed.

[0067] Thereafter, by rotating the cam lever 65 about the axis C2 of the support shaft 67, the pressing portion 65b is displaced from the pressing release position to the pressing position with respect to the axis C2. As a result, the second spring seat 63 approaches the first spring seat 62. This compresses the compression spring 61, and the biasing force of the compression spring 61 is generated or increased on the inner lid 51 in a direction away from the support shaft 67 of the cam support 66, i.e., downward. In this manner, the retainer 53 is configured to hold the second spring seat 63 in a state in which the second spring seat 63 is displaced with respect to the first spring seat 62 so that the compression spring 61 biases the inner lid 51 toward the battery pack 11.

[0068] In this embodiment, the inner lid 51 or the battery pack 11 that is not pressed by the pressing mechanism 50 is configured not to completely close the lower opening P2. That is, when the inner lid 51 is not pressed by the pressing mechanism 50, a slight gap is formed between a part of the periphery of the lid main body 51a and the base 22. This gap disappears when the inner lid 51 is pressed by the pressing mechanism 50. When the inner lid 51 is not pressed by the pressing mechanism 50, the inner lid 51 does not need to abut against the battery pack 11, but may abut against the battery pack 11 when pressed.

[0069] (Battery pack removal procedure) The procedure for removing the battery pack 11 from the motorcycle 1 (more specifically, the battery case 20) will be described below. First, the lock on the outer lid 30 by the lock mechanism 40 is released by operating the key, and then the outer lid 30 is rotated from the closed position to the open position as shown in FIG.

[0070] Next, the casing 70 is removed from the accommodation space S to the outside through the upper opening P1.

[0071] Next, as shown in FIG. 7, the cam lever 65 is rotated about the axis C2 to reduce the pressing force of the compression spring 61. Thereafter, the cam lever 65 is rotated about the axis C3 to align the locking portion 66b with an orientation that allows it to be inserted into the locking hole 68. Thereafter, as shown in FIG. 8, the cam lever 65 is lifted upward to rotate the inner lid 51 about the axis C1 of the engaged shaft 51b. Next, the inner lid 51 is moved so that the engaged shaft 51b is released from the engaging hook 52, and then the inner lid 51 is removed from the storage space S to the outside through the upper opening P1. Thereafter, the battery pack 11 inside the case body 21 is pulled upward and removed from the storage space S to the outside through the upper opening P1.

[0072] This completes the removal of the battery pack 11 from the motorcycle 1. The operation of storing the battery pack 11 in the motorcycle 1 can be performed by reversing the procedure of the operation of removing the battery pack 11.

[0073] (Action and effect) As described above, according to the motorcycle 1 of this embodiment, the inner lid 51 abutting against the battery pack 11 is held in a state of being pressed against the battery pack 11. This prevents the battery pack 11 from moving inside the battery case 20. Furthermore, because the outer lid 30 is connected to the battery case 20 bypassing the pressing mechanism 50, it is not subjected to the pressing reaction force of the battery pack 11, improving design freedom. For example, the outer lid 30 can be specialized for a structure that prevents rainwater and the like from entering the battery case 20, without considering the pressing reaction force for fixing the battery pack 11. This allows for a simple configuration of the lid body, and prevents the battery pack 11 from moving.

[0074] Furthermore, in this embodiment, since the pressing mechanism 50 is disposed within the storage space S, it is protected by the battery case 20, which prevents foreign matter (e.g., sand, pebbles, rainwater, etc.) from adhering to the pressing mechanism 50, thereby preventing damage to the pressing mechanism 50.

[0075] In addition, in this embodiment, the inner lid 51 is configured to be detachable from the battery case 20, so that interference with the inner lid 51 can be prevented when attaching or detaching the battery pack 11 to or from the battery case 20, making the attachment and detachment work easier.

[0076] In this embodiment, the second partition wall 73 can prevent the contents contained in the casing 70 from coming into contact with the retainer 53.

[0077] Furthermore, in this embodiment, one pressing mechanism 50 can both lock the inner lid 51 in contact with the battery pack 11 to the battery case 20 and press the battery pack 11 downward.

[0078] Furthermore, in this embodiment, the operating member 64 can be used to both lock the inner lid 51 to the battery case 20 and press the battery pack 11 downward. Furthermore, in this embodiment, the locking portion 66b and the pressing portion 65a can be displaced by operating the cam lever 65, thereby improving operability compared to when locking and pressing operations are performed using multiple different operating elements. With the above configuration, a biasing force that biases the inner lid 51 downward can be generated by an intuitively easy-to-understand operation for the user, namely, tilting and raising the cam lever 65.

[0079] In this embodiment, the engaging member 52 engages with the inner lid 51 on the opposite side of the pressing mechanism 50 across the battery pack 11. Therefore, the number of pressing mechanisms 50 can be reduced compared to when pressing mechanisms 50 are provided on both sides of the battery pack 11.

[0080] Second Embodiment Next, a motorcycle according to a second embodiment will be described with reference to Figures 9 to 11. In the second embodiment, components similar to those in the first embodiment are designated by the same reference numerals, and their description will be omitted. Figure 9 is an enlarged perspective view of the vicinity of the retainer 83 in the pressing state of the pressing mechanism 80 in the second embodiment. Figure 10 is a side cross-sectional view of the retainer 83. Figure 11 is a view illustrating the state in which the inner lid 51 of the pressing mechanism 80 is slightly open.

[0081] The present embodiment differs from the first embodiment in the structure of the retainer in the pressing mechanism. More specifically, while the retainer 53 in the pressing mechanism 50 of the first embodiment is of a cam lever type, the retainer 83 in the pressing mechanism 80 of the present embodiment is of a cylindrical cam type. Like the retainer 53 in the first embodiment, the retainer 83 is disposed behind the lower opening P2 in the base 22 (more specifically, the lower base frame 24) when the inner lid 51 is in the closed position. Like the retainer 53, the retainer 83 has both a pressing function for pressing the inner lid 51 and a locking function for locking the inner lid 51 to the battery case 20.

[0082] The retainer 83 includes a compression spring 61, a first spring seat 62, a second spring seat 63, an operating member 84, and a locked portion 88. The configurations of the compression spring 61, the first spring seat 62, the second spring seat 63, and the support portion 51c of the inner lid 51 that supports them are the same as those in the above embodiment, and therefore description thereof will be omitted.

[0083] The operating member 84 is connected to the inner lid 51 so as to be displaceable relative to the inner lid 51. For example, the operating member 84 is connected to the support portion 51c of the inner lid 51 so as to be rotatable around the axis C3. Furthermore, the operating member 84 is connected to the support portion 51c of the inner lid 51 so as to be displaceable in the direction of the axis C3 relative to the inner lid 51.

[0084] The operating member 84 includes a rotary handle 85 that is operated by the user with his / her hand, and a rotary shaft 86. The rotary handle 85 corresponds to an operator. The rotary handle 85 is disposed on the opposite side of the second spring seat 63 from the compression spring 61. The rotary handle 85 is a handle for rotating the cylindrical portion 101 around the axis C3. In this embodiment, the rotary handle 85 has a shape that is point-symmetrical with respect to the axis C3.

[0085] The rotary handle 85 is fixed to one end of a rotary shaft 86. The rotary shaft 86 passes through the second spring seat 63, the compression spring 61, and the radially inner side of the first spring seat 62. The rotary shaft 86 also passes through a through-hole 103 in the bottom 102 of the cylindrical portion 101 of the support part 51c.

[0086] The rotating shaft 86 has a pressing portion 86a and a locking portion 86b. The pressing portion 86a is located on the opposite side of the second spring seat 63 from the compression spring 61. The pressing portion 86a presses the second spring seat 63 toward the compression spring 61. The second spring seat 63 is sandwiched between the pressing portion 86a and the compression spring 61.

[0087] The locking portion 86b is a pin-shaped protrusion that protrudes in a direction perpendicular to the axis C3. Hereinafter, the locking portion 86b may be referred to as a locking pin 86b. The locking pin 86b is located on the opposite side of the through-hole 103 from the compression spring 61.

[0088] The locking pin 86b has a size or shape that prevents it from being inserted into the through-hole 103. Therefore, when the operation member 84 is lifted upward, the inner lid 51 is also lifted by being supported by the locking pin 86b.

[0089] The locked portion 88 includes a hollow cylindrical cam 89 fixed to the battery case 20. The cylindrical cam 89 is sized to be able to engage with the locking pin 86b. In other words, the inner diameter of the cylindrical cam 89 is shorter than the length from the axis C3 to the radially outer end of the locking pin 86b.

[0090] The cylindrical cam 89 has an engagement hole 89a that can engage with the locking pin 86b. The upper end of the engagement hole 89a is located at the upper edge of the cylindrical cam 89, and the locking pin 86b can move in and out of the engagement hole 89a in the vertical direction from the upper end of the engagement hole 89a. The engagement hole 89a has a spiral shape that guides the locking pin 86b downward when the operating member 84 rotates about an axis C3 that extends in the biasing direction of the compression spring 61. In addition, the lower end of the engagement hole 89a has a shape that holds the locking pin 86b. For example, the lower end of the engagement hole 89a may have a shape that extends along a plane perpendicular to the central axis of the cylindrical cam 89.

[0091] In this pressing mechanism 80, by rotating the rotary handle 85 about the axis C3 when the inner lid 51 is in the abutting position, it is possible to simultaneously lock the inner lid 51 to the battery case 20 and hold the inner lid 51 in a downward pressed state. When the inner lid 51 is in the abutting position, more specifically, by rotating the rotary handle 85 while pressing it downward, the locking pin 86b is inserted into the engagement hole 89a and guided downward in a spiral until it reaches the lower end of the engagement hole 89a. In this way, the biasing force of the compression spring 61 is generated or increased in a direction pressing the inner lid 51 downward. With the locking pin 86b held in the lower end of the engagement hole 89a, the inner lid 51 can be locked to the battery case 20 in a downward pressed state.

[0092] The following describes the procedure for removing the battery pack 11 from the motorcycle 1 (more specifically, the battery case 20) equipped with the pressing mechanism 80. Rotating the outer lid 30 from the closed position to the open position and removing the casing 70 from the storage space S to the outside through the upper opening P1 are the same as the procedure for removing the battery pack 11 described in the above embodiment.

[0093] After moving the outer lid 30 to the open position and removing the casing 70, the rotating handle 85 of the retainer 83, which is in the pressed state shown in FIG. 9, is rotated about the axis C3, causing the locking pin 86b to spiral upward from the lower end of the engagement hole 89a (i.e., the locking position). Since the pressing portion 86a gradually rises along with the locking pin 86b, the biasing force of the compression spring 61 gradually decreases. After rotating the rotating handle 85 to a rotation position (i.e., the unlocked position) where the locking pin 86b can be released from the engagement hole 89a, the rotating handle 85 is then lifted upward. As a result, as shown in FIG. 11, the locking pin 86b leaves the engagement hole 89a from the upper end of the cylindrical cam 89, and the inner lid 51 rotates about the axis C1 of the engaged shaft 51b. The subsequent steps overlap with those described in the first embodiment, and therefore will not be described again.

[0094] <Third embodiment> Next, a motorcycle according to a third embodiment will be described with reference to Figures 12 to 15. In the third embodiment, components similar to those in the first and second embodiments are designated by the same reference numerals, and descriptions thereof will be omitted. Figure 12 is an enlarged side cross-sectional view of the vicinity of the upper part of battery case 120 of a motorcycle according to the third embodiment.

[0095] The pressing mechanism 150 of the present embodiment includes an inner lid 151, an engaging member 152, and a retainer 183. Basically, the roles of the inner lid 151, the engaging member 152, and the retainer 183 in the pressing mechanism 150 are the same as the roles of the inner lid 51, the engaging member 52, and the retainers 53, 83 in the pressing mechanisms 50, 80 of the first and second embodiments, respectively. However, the positions and structures of the inner lid 151, the engaging member 152, and the retainer 183 in the pressing mechanism 150 are slightly different from those of the inner lid 51, the engaging member 52, and the retainers 53, 83 in the pressing mechanisms 150 of the first and second embodiments, respectively.

[0096] For example, in the pressing mechanism 150 of this embodiment, the positions of the engaging member 152 and the retainer 183 are opposite to those of the engaging member 52 and the retainers 53, 83 in the pressing mechanism 80 of the first and second embodiments. As shown in Fig. 12, the engaging member 152 is disposed behind the lower opening P2 in the base 22 (more specifically, the lower base frame 24). Furthermore, the retainer 183 is disposed in front of the lower opening P2 in the base 22 (more specifically, the lower base frame 24) when the inner lid 151 is in the abutting position.

[0097] Fig. 13 is a top view of the inner lid 151 in the third embodiment. Fig. 14 is a perspective view for explaining the configuration of the pressing mechanism 150 in the third embodiment. In Fig. 14, the left half of the inner lid 151 is omitted so that the structure of the retainer 183 can be easily seen.

[0098] In this embodiment as well, the inner lid 151 is detachable from the battery case 120. As shown in Fig. 13, the inner lid 151 includes a lid main body 151a, an engaged portion 151b, and a support portion 151c. The lid main body 151a closes the opening P2 when the inner lid 151 is in an abutting position where it abuts against the battery pack 11.

[0099] In this embodiment, a partition wall 172 and a pair of side walls 174 are provided on the top surface of the lid main body 151a. The partition wall 172 rises upward from near the rear edge of the lid main body 151a. The pair of side walls 174 extend forward from both left and right ends of the partition wall 172. The space sandwiched between the pair of side walls 174 in the operating direction functions as a luggage storage space for storing luggage as storage items. The partition wall 172 prevents storage items placed on the top surface of the lid main body 151a from moving behind the lid main body 151a, i.e., into the space where the engaging member 152 is located (see FIG. 12). As such, in this embodiment, the inner lid 151 itself functions as a casing on which storage items are placed, eliminating the need for a separate casing 70 to be placed on the inner lid 151 as in the first and second embodiments.

[0100] The engaged portion 151b is fixed to the rear end of the lid main body 151a. The engaged portion 151b is engageable with an engaging member 152 fixed to the battery case 20. The engaged portion 151b has a rod shape extending in the left-right direction. Hereinafter, the engaged portion 151b may also be referred to as an engaged shaft 151b.

[0101] 14, the engaging member 152 has an engaging structure that allows it to be attached to and detached from the inner lid 151. The inner lid 151 is rotatable about the axis C1 of the engaged shaft 151b when the engaged shaft 151b is engaged with the engaging member 152. The engaging member 152 has a hook shape, similar to the engaging member 52. Note that the hook shape of the engaging member 152 is a hook shape that opens toward the lower opening P2, but it may also be a hook shape that opens on the side opposite to the side where the lower opening P2 is located.

[0102] 14, the support portion 151c is fixed to the side of the lid main body 151a opposite to the engaged portion 151b, i.e., to the front end portion of the lid main body 151a. The support portion 151c supports a compression spring 61 (described later) and other components of the retainer 53. When the inner lid 151 is in the abutting position, the retainer 183 is disposed in front of the lower opening P2 in the base 22 (more specifically, the lower base frame 24).

[0103] The retainer 183 holds the inner lid 151, which is in contact with the battery pack 11, in a state in which it is pressed toward the battery pack 11. That is, the retainer 183 has a pressing function that presses the inner lid 151 downward when the inner lid 151 is in the contact position. The retainer 183 also has a locking function that locks the inner lid 151 to the battery case 120 when the inner lid 151 is in the contact position.

[0104] The retainer 183 includes a compression spring 61, a first spring seat 62, a second spring seat 63, an operating member 184, and a locked portion 188. The configurations of the compression spring 61, the first spring seat 62, the second spring seat 63 in the retainer 183, and the support portion 151c of the inner lid 151 that supports them are the same as those in the first and second embodiments, and therefore description thereof will be omitted.

[0105] The retainer 183 in this embodiment is of a cylindrical cam type, similar to the retainer 83 in the second embodiment. The operating member 184 includes a rotary handle 185 that is operated by a user with his or her hand, and a rotary shaft 86. Whereas the rotary handle 85 of the operating member 84 in the second embodiment has a shape that is point-symmetrical about the axis C3, the operating member 184 in this embodiment has a shape that extends in only one direction from the axis C3. Except for the shape of the rotary handle 185, the operating member 184 in the retainer 183 and the operating member 84 in the second embodiment have substantially the same configuration, and therefore a description of the rotary shaft 86 of the operating member 184 will be omitted.

[0106] Similar to the second embodiment, the locked portion 188 includes a cylindrical cam 89. The locked portion 188 of the retainer 183 has the same configuration as the locked portion 88 of the second embodiment, and therefore a description of the locked portion 188 will be omitted.

[0107] In this embodiment, as in the second embodiment, by rotating the rotary handle 185 about the axis C3 when the inner lid 151 is in the abutting position, it is possible to simultaneously lock the inner lid 151 to the battery case 120 and hold the inner lid 151 in a downwardly pressed state. When the inner lid 151 is in the abutting position, more specifically, by rotating the rotary handle 185 while pressing it downward, the locking pin 86b is inserted into the engagement hole 89a and guided downward in a spiral manner until it reaches the lower end of the engagement hole 89a (i.e., the locking position). At this time, as shown in FIG. 13 , in this embodiment, the rotary handle 185 is extended leftward from the axis C3. The locking pin 86b is held in the lower end of the engagement hole 89a, allowing the inner lid 151 to be locked to the battery case 120 in a downwardly pressed state.

[0108] In this embodiment, as shown in Fig. 12, a protruding member 90 is disposed on the back surface of the outer lid 30, i.e., from the outer lid 30 in the closed position, and protruding downward. In this example, the protruding member 90 is a rod-shaped body attached to the outer lid 30, but the shape of the protruding member is not particularly limited. The protruding position and length in the protruding direction from the outer lid are adjusted so that when the outer lid 30 is closed, the protruding member 90 interferes with the retainer 183 in the released state but does not interfere with the retainer 183 in the pressed state. This will be described with reference to Fig. 15.

[0109] Figure 15 is an enlarged side cross-sectional view showing the vicinity of the retainer 183 in the pressed state in the third embodiment. Figure 15 also shows the lower end of the protruding member 90 when the outer lid 30 is in the closed position. In this embodiment, the protruding member 90 is attached to the outer lid 30 so that the protruding member 90 is positioned on the axis C3 of the rotation shaft 86 of the operating member 184 when the outer lid 30 is closed. There is a slight gap G between the retainer 183 in the pressed state and the protruding member 90 protruding from the outer lid 30 in the closed state, so the retainer 183 in the pressed state and the protruding member 90 do not interfere with each other.

[0110] 15, the rotation handle 185 of the retainer 183 in the released state is shown by a two-dot chain line. The position of the operating member 184 of the retainer 183 in the released state is higher than the position of the operating member 184 of the retainer 183 in the pressed state, and the operating member 184 of the retainer 183 in the released state interferes with the protruding member 90. Therefore, even if the outer lid 30 is rotated from the open position while the retainer 183 is in the released state, the interference between the operating member 184 and the protruding member 90 prevents the outer lid 30 from closing while the retainer 183 is in the released state.

[0111] As shown in FIG. 15, in this embodiment, the protruding member 90 is provided on the outer lid 30 so as to interfere with the rotation axis 86 of the retainer 183 in the released state, but the protruding member 90 may also be provided on the outer lid 30 so as to interfere with other elements of the retainer 183 in the released state, such as the rotation handle 185.

[0112] In this embodiment, the lock mechanism 140 that holds the outer lid 30 in the closed position also differs from the lock mechanism 40 described in the first embodiment. Specifically, the lock mechanism 140 of this embodiment includes a receptacle 141, a lock moving part 142, and a lock fixed part 143, similar to the lock mechanism 40 of the first embodiment. However, the receptacle 141 and the lock moving part 142 are provided on the outer lid 30, not on the base 22. Furthermore, the lock fixed part 43 is provided on the base 22, more specifically, on the upper base frame 23, not on the outer lid 30. In this way, by providing the lock moving part 142, which is a movable part, on the outer lid 30 side, the portion of the upper base frame 23 forward of the outer lid 30 can be made smaller, and as a result, the upper opening P1 can be designed to be larger. This makes it easier to design the upper opening P1 to allow the battery pack 11 and the inner lid 151 to pass through easily.

[0113] <Fourth embodiment> Next, a motorcycle according to a fourth embodiment will be described with reference to Figures 16 and 17. In the fourth embodiment, components similar to those in the first to third embodiments are designated by the same reference numerals, and descriptions thereof will be omitted. Figure 16 is a side cross-sectional view showing an enlarged view of the vicinity of the upper part of the battery case of a motorcycle according to the fourth embodiment. Figure 17 is a perspective view showing an enlarged view of a portion of the interior of the accommodation space in the fourth embodiment.

[0114] 16, in this embodiment, a partition plate 91 protrudes downward as a protruding member from the outer lid 30 in the closed position. The protruding position and length of the partition plate 91 from the outer lid 30 in the protruding direction are adjusted so that when the outer lid 30 is closed, the partition plate 91 interferes with the retainer 183 in the released state but does not interfere with the retainer 183 in the pressed state.

[0115] Specifically, as shown in Fig. 17, when the retainer 183 is in the pressed state, the rotary handle 185 extends leftward from the axis C3 (see also Fig. 13). In other words, when the retainer 183 is in the pressed state, the lid main body 151a and the rotary handle 185 do not overlap when the inner lid 151 is viewed from above.

[0116] Meanwhile, the partition plate 91 is provided on the outer lid 30 so as to be located directly above the front end of the lid body 151a, that is, the end of the lid body 151a on the side where the support portion 51c is located, when the outer lid 30 is closed. Therefore, when the outer lid 30 is closed with the retainer 183 in the pressed state, the partition plate 91 does not interfere with the rotary handle 185.

[0117] 16 and 17, the rotating handle 185 of the retainer 183 in the released state is shown by a two-dot chain line. When the retainer 183 is in the released state, the rotating handle 185 extends from the axis C3 toward the lid main body 151a (see also the two-dot chain line in FIG. 13). That is, when the retainer 183 is in the released state, the lid main body 151a and the rotating handle 185 overlap when the inner lid 151 is viewed from above. Therefore, when the outer lid 30 is closed with the retainer 183 in the released state, the partition plate 91 interferes with the rotating handle 185.

[0118] Therefore, even if the outer lid 30 is rotated from the open position while the retainer 183 is in the released state, interference between the operating member 184 and the partition plate 91 as a protrusion prevents the outer lid 30 from closing while the retainer 183 is in the released state.

[0119] Furthermore, in this embodiment, when the outer lid 30 is closed with the retainer 183 in the pressed state, the partition plate 91 separates the storage space S into a space in which the retainer 183 is disposed and an luggage storage space above the lid main body 151a. Therefore, the partition plate 91 prevents items placed on the top surface of the lid main body 151a from moving forward of the lid main body 151a, i.e., into the space in which the retainer 183 is disposed.

[0120] <Other embodiments> The present disclosure is not limited to the above-described embodiments, and the configurations thereof can be changed, added, or deleted.

[0121] For example, in the above embodiment, the saddle-riding vehicle is an electric vehicle using an electric motor as a propulsion source, but it may also be a vehicle equipped with an engine as a propulsion source. The battery pack may be a battery pack that is not a propulsion source but is capable of supplying power to an electric motor that assists engine drive. The saddle-riding vehicle may also be an electrically assisted bicycle that uses an electric motor to assist human power.

[0122] The configuration, posture, etc. of the battery case are not limited to those described in the above embodiment. In the above embodiment, the battery case is configured such that the case body and the base are connected to each other, but the battery case may be configured such that the case body and the base are integrated. For example, in the above embodiment, the base 22 may be only the upper base frame 23, and the lower base frame 24 may be part of the case body 21. In this case, the engaging member 52 and the locked portion 68 may be fixed to the case body 21 rather than the base 22.

[0123] In the above embodiment, the base includes the protruding portion, but the base and the protruding portion may be separate bodies.

[0124] The pressing mechanism may be an air spring instead of a compression spring. Alternatively, if the inner lid is elastic, the pressing mechanism may be a mechanism that presses with a fastener such as a bolt. In other words, if the inner lid is elastic, the abutting member itself may have the pressing function.

[0125] The inner lid may have a cushioning material at the contact point with the battery pack. Also, in the above embodiment, the contact member is the inner lid, but the contact member does not have to be a lid that covers the battery pack from above. For example, it may be something that contacts the battery pack without closing the opening P2. For example, the contact member may be a rod-shaped member or a mesh-shaped member. The inner lid does not have to be detachable from the battery case.

[0126] The operator of the pressing mechanism is the part that the user touches with their hand when operating the pressing mechanism. The shape and configuration of the operator are not limited to those described in the above embodiment and modified examples. For example, the operator may be a lever, a handle, a knob, a button, or the like.

[0127] Although the casing serving as a luggage case includes the partition wall, the luggage case and the partition wall may be separate bodies. A saddle-ride vehicle does not have to be provided with a luggage case.

[0128] In the above embodiment, the battery pack 11 stored in the first space S1 and the luggage stored in the second space S2 are described as examples of items stored in and removed from the storage space S. However, the stored items are not limited to these. For example, the stored items do not have to include a battery pack. The case forming the storage space does not have to be a battery case, and may be, for example, a case shaped to store only luggage. For example, the battery pack does not have to be detachable from the vehicle body. Furthermore, the saddle-riding vehicle may be a vehicle that can be driven without a battery pack. The saddle-riding vehicle may be a vehicle that uses a driving source other than an electric motor, such as an internal combustion engine, as its driving source. For example, the stored items may be accessories worn by the driver while driving, such as a helmet or gloves. Furthermore, the stored items may be a toolbox, an instruction manual, or a vehicle part that is intended to be attached to or detached from the vehicle body.

[0129] [Disclosure items] Each of the following sections is a disclosure of a preferred embodiment.

[0130] [Item 1] a battery case having an accommodation space for accommodating a battery pack and an opening for attaching and detaching the battery pack, the opening opening the accommodation space; a pressing mechanism including: a contact member that can come into contact with the battery pack when the battery pack is accommodated in the accommodation space of the battery case; and a retainer that holds the contact member that comes into contact with the battery pack in a state in which the contact member is pressed toward the battery pack; a cover body that is connected to the battery case bypassing the pressing mechanism and that opens and closes the opening of the battery case.

[0131] According to the above items, the abutting member abutting against the battery pack is held in a state of being pressed against the battery pack. This prevents the battery pack from moving inside the battery case. Furthermore, because the lid is connected to the battery case bypassing the pressing mechanism, it is not subjected to the pressing reaction force of the battery pack, improving design freedom. For example, the lid can be specialized in a structure that prevents rainwater and the like from entering the battery case without considering the pressing reaction force for fixing the battery pack. This allows for a simple configuration of the lid and prevents the battery pack from moving.

[0132] [Item 2] Item 2. The saddle riding vehicle according to item 1, wherein the pressing mechanism is disposed within the accommodation space. According to the above items, the pressing mechanism is protected by the battery case, and foreign matter (for example, sand, pebbles, rainwater, etc.) can be prevented from adhering to the pressing mechanism, thereby preventing damage to the pressing mechanism.

[0139] [Item 9] The operating member is a camshaft disposed on the opposite side of the compression spring with respect to the second spring seat; 9. The saddle-ride vehicle according to claim 8, further comprising: a cam lever that abuts against the second spring seat and rotates about the cam shaft to change the position of the second spring seat relative to the first spring seat. According to the above items, a biasing force that biases the contact member downward can be generated by an intuitive operation that is easy for a user to understand, that is, by tilting or raising the cam lever.

[0140] [Item 10] the engaged portion includes a hollow cylindrical cam having an engagement hole and fixed to the battery case, the locking portion is an engagement pin that can be engaged with the engagement hole, the engagement hole has a spiral shape that guides the engagement pin downward when the operating member rotates around a rotation axis that extends in the biasing direction of the compression spring, 9.
