摘要： The present invention discloses a steering wheel enabling suppressing hanging down of an airbag module due to its own weight and stabilizing the position of the airbag module. A steering wheel 1 includes a steering wheel body 2, an airbag module 3, and at least one coil spring 62 that biases the airbag module 3 in a direction separating from the steering wheel body 2. The coil spring 62 is arranged between the steering wheel body 2 and the airbag module 3 in a state with the axis line thereof offset from that of a free state; thereby applying a force F2 on the airbag module 3 in a direction that intersects with the axis line L1 of the coil spring in a free state.

摘要： A quick-disassembly assembly for a steering wheel (10) and a steering column (20), including a steering wheel shaft (1) and a connecting block (2), the steering wheel shaft (1) being disposed in an inner wall of the steering wheel (10), the connecting block (2) being connected to the steering column (20), and a guide slot (21) and a positioning block (22) being provided in the connecting block (2). When the steering wheel shaft (1) slides into the guide slot (21) and is positioned with the positioning block (22), the steering wheel (10) is connected to the steering column (20). When the steering wheel shaft (1) slides out from the guide slot (21), the steering wheel (10) is separated from the steering column (20). The connection between the steering wheel (10) and the steering column (20) is achieved by means of the connecting block (2). During connection, the steering wheel shaft (1) of the steering wheel (10) is slid into the guide slot (21) of the connecting block (2) and is positioned with the positioning block (22). During disassembly, the steering wheel shaft (1) is slid out of the guide slot (21), such that the disassembly of the steering wheel (10) and the steering column (20) may be achieved. The quick-disassembly assembly is simple to operate, and the quick disassembly and assembly of the steering wheel (10) and the steering column (20) can be achieved.
