A coupler includes a first connector and a second connector. The first connector includes a first connector main body and the first connector valve member. The second connector includes a second connector main body and a second connector valve member. A part of the first connector valve member is to be inserted in an insertion portion of the second connector and a seal between an outer circumference of the first connector valve member and an inner circumference of insertion portion of the second connector is formed by a seal on the first connector valve member. An axial length from a leading end of the second connector main body to a leading end of the second connector valve member is larger than an axial length from a leading end of the first connector valve member to the seal.
