A flow measuring device includes a housing, a support, and a flow measurement element. The housing defines a passage therein and includes a passage narrowing part, which reduces a cross-sectional area of the passage, in a predetermined part of the passage. The support has a platy shape and is disposed along a flow direction of fluid flowing in the passage. The flow measurement element is located inside the passage narrowing part and is disposed on a surface of the support. The flow measurement element detects a flow rate of fluid flowing in the passage. The passage narrowing part has an inner wall surface that gradually reduces a width of the passage from a center side to both end sides of the passage in a height direction of the passage, which is perpendicular to a direction of the width of the passage.

A battery module is configured so that the first cell string and the second cell string are arranged between the first plate member and the second plate member and the second cell string is arranged closer to the second plate member side than the first cell string is and is arranged closer to the outlet side than the first cell string is. At the inlet side of the housing, the inlet is arranged closer to the first plate member than to the second cell string, at least a part between the inlet side of the second cell string and the second plate member is covered by the inlet-side guide plate, and the cooling air is introduced into the housing through the inlet so as to form a flow of the cooling air along the first plate member and a flow of the cooling air along the inlet-side guide plate.

A motor structure for varying a counter electromotive force is provided. The motor structure includes a rotor that is fixed annularly and concentrically to a radially outside from an exterior circumferential surface of a shaft of an electric motor and has a permanent magnet, and a stator that has coils positioned on the interior side of a motor housing and on the concentrically exterior side with the permanent magnet of the rotor. Further, the coils are positioned spaced apart from each other at predetermined intervals. A drive unit moves the stator in the axial direction of the shaft to vary the interlinkage flux, by varying an area that the magnetic flux of the permanent magnet of the rotor passes through the coils of the stator.

A cantilever-type vehicle-carrying board with one parking space for parking two vehicles, comprising a hollow vehicle frame that can be accommodated in the parking space and has a running mechanism. The vehicle frame is provided with a cantilever-type vehicle-carrying The upper part of the board is the upper parking space, and the hollow of the frame is the lower parking space. The frame includes two arms symmetrically arranged on the left and right sides. It is composed of a horizontal base and a vertical guide groove body perpendicular to each other. A connecting beam; the two sides of the end of the cantilever-type vehicle-carrying board are respectively connected with the left and right two frame arms; the extension length of the horizontal base of the frame-arm is only half of that of the cantilever-type vehicle-carrying board; the vehicle lifting mechanism includes a hydraulic The cylinder plunger is connected to a multi-link device; the other end of the cylinder plunger is connected to the vehicle frame. The invention has the advantages of unique structure, adopting a cantilever-type car-carrying plate and driven up and down by a multi-connection transmission rod mechanism, reducing the passage area required in front of the parking space and improving parking efficiency; it can be used for one parking space in a family garage; It is used in continuous arrangement of multiple parking spaces such as public parking lots or underground garages.
