Device with assembly mechanism and electric pump

Abstract

A device with an assembly mechanism may be provided. The device with the assembly mechanism may include: a first member; a second member; and a fastener fastening the first member and the second member to each other. The fastener may include a fastening portion being fastened to each of the first member and second member by injection welding; and the assembly mechanism that is integrally formed with the fastening portion, and is configured to assemble the device to an external device.

1 . A device with an assembly mechanism, comprising:
 a first member;   a second member; and   a fastener fastening the first member and the second member to each other,   wherein the fastener comprises;
 a fastening portion being fastened to each of the first member and second member by injection welding; and 
 the assembly mechanism that is integrally formed with the fastening portion, and is configured to assemble the device to an external device. 
   
     
     
         2 . The device with the assembly mechanism as in  claim 1 , wherein
 the first member comprises a first opposing portion,   the second member comprises a second opposing portion opposing the first opposing portion, and   the fastener further comprises a first contacting portion contacting the first opposing portion at a side of the first opposing portion opposite from the second opposing portion.   
     
     
         3 . The device with the assembly mechanism as in  claim 2 , wherein
 the first member further comprises a first holding portion disposed at a side of the first contacting portion opposite from the first opposing portion, and   the first contacting portion is interposed between the first opposing portion and the first holding portion.   
     
     
         4 . The device with the assembly mechanism as in  claim 2 , wherein
 the fastener further comprises a second contacting portion contacting the second opposing portion at a side of the second opposing portion opposite from the first opposing portion.   
     
     
         5 . The device with the assembly mechanism as in  claim 4 , wherein
 the second member further comprises a second holding portion disposed at a side of the second contacting portion opposite from the second opposing portion, and   the second contacting portion is interposed between the second opposing portion and the second holding portion.   
     
     
         6 . The device with the assembly mechanism as in  claim 1 , wherein the fastener and at least one of the first member and the second member engage with each other to restrict the fastener from moving in a direction perpendicular to a direction in which the first member and the second member are arranged. 
     
     
         7 . An electric pump comprising:
 an upper housing;   a lower housing;   a flange fastening the upper housing and the lower housing to each other,   wherein the flange comprises:   a fastening portion being fastened to each of the upper housing and the lower housing by injection welding; and   an assembly mechanism that is integrally formed with the fastening portion, the assembly mechanism including a fastening hole, and   a fastener member to be fastened to an external device is inserted through the fastening hole.
