Electromagnetic actuator
In the present invention, a through hole (33) through which a rod (17) is inserted is formed in an electromagnetic drive unit (MD), the rod (17) comprising an outer wall surface (42) that slides along the through hole (33). A clearance (CB) from the outer wall surface (42) of the rod (17) located in...

| description | In the present invention, a through hole (33) through which a rod (17) is inserted is formed in an electromagnetic drive unit (MD), the rod (17) comprising an outer wall surface (42) that slides along the through hole (33). A clearance (CB) from the outer wall surface (42) of the rod (17) located in a maximum protrusion position to an inner wall surface (34) of the through hole (33) is smaller than a clearance (CA) from the outer wall surface (42) of the rod (17) located in a maximum retracted position to the inner wall surface (34). Through this, the clearance when retracted is relatively large, making it possible to reduce the friction forces between the rod (17) and a support tube portion (32). In addition, the clearance when protruded is relatively small, making it possible to reduce the amount a tip portion (44) of the rod (17) shakes in the radial direction.
