Coupler for railway model, and railway model vehicle

A coupler for a railway model comprising:

• a first half cylindrical section having a substantially half cylindrical shape;
• a second half cylindrical section, having a substantially half cylindrical shape, facing the first half cylindrical section on a circle substantially concentric with the first half cylindrical section, and having an inner diameter greater than that of the first half cylindrical section;
• a first engagement section provided in a projecting manner on an inner peripheral surface of the second half cylindrical section;
• and
• a second engagement section provided in a recessed manner on an outer peripheral surface of the first half cylindrical section, at a position enabling engagement with the first engagement section on a same type of a coupler to be coupled with, and having a recess width in a circumferential direction greater than a projection width in a circumferential direction of the first engagement section.

A coupler for a railway model comprising:

• a first cylinder having a substantially cylindrical shape;
• and
• a first engagement section provided in a projecting manner on an outer peripheral surface of the first cylindrical section, at a position enabling engagement with a second engagement section provided in a recessed manner on an inner peripheral surface of a second cylindrical section, having a substantially cylindrical shape, of a different type of a coupler for a railway model to be coupled with, wherein:
• an outer diameter of the first cylindrical section is smaller than an inner diameter of the second cylindrical section;
• and
• a projection width in a circumferential direction of the first engagement section is smaller than a recess width in a circumferential direction of the second engagement section.
