Description of the Related Art In recent years, in a conventional railway vehicle for passenger transportation, for the purpose of shortening the manufacturing period, reducing costs, etc., a front (operating cabin) is manufactured separately from a vehicle underframe and a passenger compartment. A method has been adopted in which this is mounted on the tip of the vehicle frame and fixed to the vehicle frame. In this method, the passenger compartment 2 is assembled on the vehicle underframe 3 and manufactured, while the forehead (driver cab) 1 is assembled separately from the passenger compartment 2 and the vehicle underframe 3, and this is assembled with the vehicle underframe 3. The forehead structure 6 of the forehead 1 is fixed to the vehicle underframe 3 through a connection bolt 5 through a bolt hole 4 placed on the front part. The connection strength of the frontal structure 6 to the vehicle underframe 3 is designed to withstand a static load, and there is no particular problem in strength. By the way, in the railway vehicle assembled as described above, there is no particular problem in strength and safety in the normal operation, but when a strong impact force is applied to the frontal head 1 rearward as described above, the frontal head 1 Since the coupling strength to the vehicle underframe is designed on the premise of a static load, the connection bolt 5 may be broken when subjected to the above-described impact force. Although such a situation must be avoided, if the connection strength of the connection bolt 5 between the frontal part 1 and the front part of the vehicle underframe 3 is made to be sufficiently resistant to the above-mentioned impact, the connection bolt It is necessary to increase the number of connection bolts 5 or make the connection bolts 5 thicker. However, if the number of connection bolts 5 is increased or the connection bolts 5 are made thicker, an increase in cost due to an increase in the number of work steps and the like is inevitable. Therefore, the front of the vehicle frame 3 and the frontal 1
It is desired to devise a simple connecting structure that can greatly improve the bonding strength without affecting the strength of the frontal structure.

る。[Effects] The frontal head 1 placed in front of the vehicle underframe has a head post 8
Is fixed to the vehicle frame 3 by the engagement between the lower end of the U-shaped notch 10 and the U-shaped notch 10 and the connection between the frontal structure 6 and the vehicle frame 3 by the connection bolts 5. The external force applied to the front end of the frontal head 1 from the front is reduced by the lower end of the end post 8 and the above-mentioned U-shaped notch 10.
Is received by engagement with Therefore, since an impact force due to a collision or the like is not applied to the connection bolt 5,
The connecting bolt 5 is not broken by the impact force. Therefore, it is possible to reduce the possibility that the connection with the vehicle frame 3 is broken at the time of the collision, the frontal head 1 is largely displaced rearward, and the passenger compartment 2 is crushed. Further, it is not necessary for the connecting bolts 5 to share the impact force from the front. Therefore, the connecting bolts 5 need only fix the frontal head 1 to the vehicle frame 3 in the vertical direction, so that the number of connecting bolts is reduced. Can be done.

The projecting portion 8a protrudes downward from the lower end of the bobbin column. The frontal head 1 is placed on the front part 3a of the vehicle underframe 3 in a state where the protruding part 8a of the post 8 is engaged with the U-shaped notch 10,
The frontal structure 6 of the forehead 1 is connected with the connecting bolt 5 as in the prior art.
Is fixed to the front part 3a of the vehicle underframe 3. Since the protruding portion 8a at the lower end of the post 8 is engaged with the U-shaped notch 10, an impact force from the front is received by this engagement. Accordingly, the impact force is not applied to the connecting bolt 5, so that the impact force does not break the connecting bolt 5, and the connecting bolt 5 is harder than the conventional connecting structure.
, The number of connecting bolts can be reduced.

ルト数を少なくすることができる。As described above, according to the present invention, the lower end of the front pillar is engaged with the above-mentioned U-shaped notch provided at the front end of the vehicle underframe. It functions as a connecting member to the underframe, and its connecting strength is extremely strong, so that it has high resistance to impact from the front. Therefore, the possibility that the frontal head is shifted rearward with respect to the entire vehicle frame due to the impact and the passenger compartment is crushed is reduced. In addition, since the lower end of the main pole functions as a connecting member to the front vehicle frame, the load on the connecting bolt is reduced, and therefore the number of connecting bolts can be reduced.
