PROBLEM TO BE SOLVED: To solve a problem that conventional carriers can satisfy a demand for improving carrying rates, because each structure of the conventional carriers is a structure for simultaneously and integrally carrying one mushroom culture vessel or laterally one row mushroom vessels in a container, but not a structure for carrying all of the vessels at once. SOLUTION: This mushroom culture vessel carrier for receiving a plurality of cylindrical mushroom culture vessels in a receiver-like container H in a rectangular arrangement state comprising a plurality of longitudinal rows and a plurality of latitudinal rows and then carrying the mushroom culture vessels in the container is characterized by disposing pressure contact members 1 capable of simultaneously pressure-contacting with the peripheral outsides of the mushroom culture vessels in longitudinal rows and in latitudinal rows placed on the outer peripheral rows in the container, disposing support members capable of supporting the pressure contact members, disposing a pressure contact mechanism capable of pressure-contacting or separating the pressure contact members with or from the mushroom culture vessels, disposing the support members in approximately V valley-like spaces existing between adjacent mushroom culture vessels in longitudinal rows and in latitudinal rows placed on the outer peripheral rows in the container, and thereby simultaneously and integrally carrying all of the mushroom culture vessels in the container by the mutual nipping of the pressure contact members.
